When the AC is tripping your electricity, it’s important to pay attention and quickly diagnose the problem.

As an experienced HVAC professional, I know all the common issues that can cause your AC system to trip the breaker.

I’ll share my knowledge and help you get your air conditioner running again quickly.

Key Takeaways

An AC breaker can trip if it is overloaded with many appliances, if there is a short circuit in the unit, or if the breaker is not sized properly.
Dirty and faulty components in an AC can often cause a breaker to trip frequently. It is also possible for a malfunctioning breaker to be the culprit.
Electrical faults are very dangerous and you should not attempt to fix them yourself. Hence, always consult with an HVAC professional.

13 Common Reasons Why Your AC Trips The Circuit Breaker (Solutions Included)

AC electrical faults cause 86% of dangerous air conditioner fires[ 1 ], and circuit breakers help you stop that from happening - but only if you know why it’s happening and what to do next.

1. The Sizing Of The Breaker Is Improper

Circuit breakers are rated by amp s , determining the amount of current that can flow through without tripping the breaker.

The average home circuit breaker is 15-20 amps for the branch circuit , which is plenty for most home AC units, but larger air conditioning systems using too many amps can cause the circuit breaker to trip[ 2 ].

You can either:

Move your air conditioning unit to a different place/room with a larger AC circuit breaker,
Hire a professional to upgrade the breaker and accompanying wiring.

TL;DR: If rated amps of a circuit breaker are lower than the rated amps of the AC, it will always trip.

2. You Are Overloading The Circuit

Each circuit breaker can only handle a certain amount of amps.

If you have other devices running through the same circuit breaker as your air conditioning system, it can o verload the AC circuit breaker and shut off your power.

Reroute other electrical devices so your AC unit can run through the breaker independently. You may need a professional to help.

TL;DR: A dedicated circuit is recommended for an AC. If too many appliances are connected to the AC circuit, it can get overloaded resulting in breaker tripping.

3. There Is A Short Circuit With The Electronic Components

ACs have internal electrical components that run continuously for hours.

Over time, the wires within the air conditioner can become damaged, leading to a ‘short’ (or short circuit).[ 3 ]

A 'short' means too much electricity is flowing through the wires and can cause overheating and fires.

The air conditioner circuit breaker will trip to shut off power and protect your home from danger.

You need to contact a professional to find the source of the short circuit and make appropriate repairs.

TL;DR: A short circuit is a very dangerous condition as it is a sign of damaged electrical components. Seek professional help if you suspect this is the case.

4. A Dirty Air Filter Heating Up Your AC

The air filter in your AC unit will get dirty over time as air flows through the machine (more so with an outdoor unit than an inside unit).

If the air filters become too dirty, they can reduce airflow and cause your air conditioner to overheat, as the electric motors must work harder.

Your air conditioner will try to draw more power to compensate for the poor airflow, tripping the breaker.

Change or clean the dirty air filter to stop your AC system from tripping the breaker.

You should be able to replace the air filter and perform regular maintenance yourself.

Important Note:

It is crucial to point out that you should avoid DIY maintenance if you have the slightest hint of doubt that things may go wrong. To avoid harming yourself or damaging your unit, always consider hiring professional help.

5. Dirty Condenser Coils Can Also Heat Up Your AC

Your condenser coils absorb the heat from the air, but they can become blocked by dust or debris (particularly if you have a dirty outside unit).

The dirty coils can strain your air conditioning system, causing it to work harder and draw more electricity.

They may lead to it tripping the breaker.

Cleaning dust and debris off the dirty condenser coils should stop the AC tripping.

You should also have an AC technician check and perform annual maintenance on your condenser.

TL;DR: Dirty filter and dirty condenser coils can heat up the internal components. Higher heat results in higher current draw resulting in your breaker tripping. Perform regular cleaning of these components.

6. Problem With Coil Fan Motor

Air conditioners use a coil fan (or AC blower) to move hot air over the condenser coil and disperse heat, leaving you with cold air.

Your coil fan can become damaged over time , and a broken coil fan can cause the AC to draw too much power, leading to the breaker tripping.

Hire a professional to perform AC repair work on the coil fan motor. It may need to be replaced to stop the breaker tripping.

TL;DR: A broken coil fan motor can draw more than its rated current, which in turn can trip the breaker.

7. Your Compressor Has Gone Bad

Your compressor houses the refrigerant that cools the air, but a faulty compressor won't cool the air.

Faults become more common as a compressor ages but can happen because of accidental damage.

A bad compressor can cause two issues:

Hard starting. Your faulty compressor won't start up properly and draws more power to try and compensate, causing it to trip its own breaker.
Grounded compressor. The wires connected to the compressor come loose, leading to a short circuit and a tripped breaker.

A technician can install a hard start kit to try and get the compressor started.

However, a faulty compressor can mean costly repairs, and it's often best to replace the entire system rather than try to fix it.

Air Conditioner Compressor Outside a Room

TL;DR: If the compressor is hard starting or if it is grounded, then it will draw far more than its rated current.

8. Cables And Wires Wear And Tear

Your AC has wires running inside the whole unit connecting electrical components.

Over time, the wires and wire insulation can become loose or damaged.

Loose wires touching the ground, floor, or other components can cause further damage to the device and your home.

The circuit breaker trips as a safety measure to avoid an electrical short and prevent damage.

Some electrical wires can be an easy fix, but electrics can be dangerous.

Have an HVAC technician check the electrical panel of the unit, find the damage, and perform the AC repair using NFPA 70E Standard Electrical Safety guidelines.[ 4 ]

A loose wire or a grounded wire is a dangerous safety hazard. You should avoid touching or going near the unit if you spot a loose connection.

9. Too Little Refrigerant

Refrigerant is the working fluid in an AC unit that cools the air.

The AC compressor has a closed system for the refrigerant, but over time, refrigerant lines can become damaged.

This damage can lead to refrigerant leaking out.

The AC compressor coils will have to work harder to cool the air if there's less refrigerant.

The unit draws more electricity to compensate, which trips the breaker.

Hire a professional to top up the refrigerant and seal the leak.

However, it may be cheaper to replace cheaper portable ACs than perform the repairs if it's out of warranty.

Refrigerant is a dangerous substance and can only be handled by professionals.[ 5 ]

TL;DR: Lower refrigerant means that the AC has to work harder in order to cool. This in turn means using up more amps to compensate. More amps = breaker tripping.

10. Frozen Evaporator Coil

Dirt, debris, and grime can build up on the evaporator coil, preventing heat from flowing and causing the coils to freeze.

The air conditioner will try to draw more energy to compensate for the frozen coils , but as it draws more amps, it can cause the breaker to trip.

You can fix this yourself by turning the power off and thawing out the compressor using a hair dryer.

Once dry, clean the evaporator coils to prevent them from malfunctioning and freezing over again.

If your air conditioner keeps tripping after this, contact a professional to determine the root cause.

11. It’s Too Hot Outside

Your air conditioner has to work harder in hot conditions to maintain the temperature, which can cause it to draw more electricity and strain the wiring.

It can also cause the breaker to trip to prevent overheating or fire hazards.

Clean the AC to keep the unit cool by improving airflow, and only use the air conditioner when needed.

If it keeps tripping the breaker, you may need to buy a new AC.

TL;DR: If the internal components are heating up due to very hot weather outside then this can lead to the breaker tripping to avoid fire hazards.

12. Failing Air Conditioning Capacitors

Your AC capacitor provides the initial jolt of electricity so it can start.

Capacitors wear out over time, and if you notice your AC has trouble starting or keeps tripping, the capacitor may be failing.

Contact an HVAC professional to fix or replace the bad capacitor.

13. You Have A Defective Circuit Breaker

A circuit breaker can become defective through natural wear and tear, exposure to extreme temperatures, or by electrical faults tripping the breaker too frequently.

A defective breaker can trip your electricals every time you use your AC.

First, make sure the breaker is actually defective.

Circuit breakers trip electrics and protect your home, a nd you should only replace them as a last resort.

If you don't resolve the issue, the new breaker will continue to trip.

Check the other common causes on the list or consult an HVAC technician to determine the issue. A professional will need to replace the circuit breaker.

TL;DR: If all else is fine, then the likely culprit is a defective breaker. Most homes have a spare breaker which you can switch your AC to. If not, then a breaker replacement will be necessary.

When To Call Professionals For Maintenance Or Repair

I recommend calling a professional to help with most air conditioning electrical problems because it can be dangerous.

Always consult a professional if you experience any of the following:

1 There is a burning smell from the breaker or AC: A burning smell indicates that your electrical wiring or AC breaker is overheating. It's a dangerous fire hazard, and you should shut off the air conditioner and contact an HVAC technician immediately.
2 There are crackling or electrical sounds from the breaker or AC: Strange noises from your inside unit usually indicate an electrical issue, loose wiring, or short-circuiting - often in the compressor motor. It is dangerous to fix yourself, and you need to contact an AC Tech professional to undertake air conditioning repair work.
3 You cannot point out where the issue lies: Your AC breaker trips the electrical supply for a reason, usually to protect you from serious danger. If your unit is tripping the AC breaker and you can't find the issue, you need to call an HVAC technician as soon as possible to diagnose the problem.

TL;DR: Electric works should always be carried out by professionals. However, some very alarming signs such as burning smell and crackling electrical sounds call for an immediate inspection. Shut off your home's main electric breaker if you experience these signs.

Why Does My AC Trip After 5 Minutes?

If your AC trips after 5 minutes, it's usually because an overloaded circuit or faulty component is drawing in too much current and tripping the circuit breaker. You should consult an electrician or HVAC professional who can help with AC repair so it doesn’t trip the breaker.

What Happens If You Trip a Breaker Too Many Times?

If your breaker trips too often, the internal trip mechanism can wear out, preventing it from working and leaving your home at risk of electrical fires. You should replace the AC's breaker if it's tripping frequently.

Should You Reset The Circuit Breaker If It Continues to Trip?

No, the circuit breaking tripping indicates an underlying electrical problem, and you should diagnose and resolve the problem before resetting it.

So, Did You Find Your Fix?

If your AC trips the breaker, it means there's a potentially hazardous electrical fault.

Cleaning and regular tune-ups of your air conditioner will help to prevent it from happening, but you will need to consult a professional if it keeps tripping your breaker .

Hopefully, this guide has helped to explain the common causes, and you now know why your AC keeps tripping the power.

AC Breaker Keeps Tripping Breaker: 9 Common Culprits & Fixes

“My AC keeps tripping the breaker. What’s wrong? How do I stop my AC from tripping the breaker?”

AC tripping the breaker is annoying. Even more troublesome, repeatedly trying to run an air conditioner that keeps tripping the breaker can result in permanent damage to the AC unit. So, easy on the breaker reset button ; you should diagnose and fix the problem first.

Here is what might be happening with your air conditioner:

Air conditioner trips the breaker immediately . When you turn the AC unit, the breaker will flip immediately or only after a few seconds.
AC trips breaker after 5 minutes or so. The AC starts OK, but after a few minutes, the breaker will trip. This, for example, is typical for the AC compressor tripping breaker (outside AC unit tripping breaker).
AC trips breaker after a few hours . An air conditioner will work fine for several hours before it trips the breaker.

To help everybody out, we are going to look at how to check why the AC unit keeps tripping the breaker. We are going to check for 9 key culprits that cause the AC circuit breaker to keep tripping.

There are only two roots for why your AC keeps tripping:

You have a faulty breaker . This involves issues with circuit breaker, AC wiring, and electrical short circuits.

sketch of air conditioner for fixing ac breaker that keeps tripping

As every HVAC professional does, you should check these culprits one by one, eliminating the causes as you go. Once you have correctly detected what is causing the AC breaker to keep tripping and fix the problem, your AC unit should work smoothly again.

Note: For every culprit, we are going to tell you if it causes the AC breaker to trip immediately, after a few minutes, or after a few hours, and explain why.

Here are the most common culprits (listed one by one) for any air conditioner type – be it central air, mini split, portable, or window air conditioner – to keep tripping the breaker. We are going to start with breaker-related issues (#1 to #3) and continue with AC unit-related issues (#4 to #9) :

Table of Contents

#1 Circuit Breaker Is Bad, Loose, Or Undersized (Causing AC To Trip Breaker Immediately)

If you are lucky, the AC breaker keeps tripping due to a bad breaker. This is one of the easiest problems to solve; problems with the AC unit itself are harder and costlier to fix.

It’s not uncommon to see a bad circuit breaker. Both new and old breakers can go bad due to wear-and-tear or acute amp surge that fries the breaker. Over time, even well-installed circuit breakers can come loose and cause all sorts of issues, including tripping unexpectedly.

In limited cases, we also see that homeowners have installed a circuit breaker that is just too small. Example: A 3-ton AC unit on 220V has a max. wattage of about 3,600 watts and requires a 25A or 30A breaker. You can check what size AC breaker you need here accounting for NEC 80% ampacity rule .

Dead giveaways of a bad breaker are:

Breaker smells like something is burning.
Breaker is hot to the touch.
Breaker keeps tripping all the time.

Solution: First, you need to check if you have a bad breaker. Secondly, check if the breaker is loose; try to nudge it from left to right to set it back in the required position. Of course, you will also have to check the above article if indeed your breaker is big enough to handle all the amps that you need to run your AC unit.

If you have a bad breaker, you just simply replace it. Get a new one – circuit breakers are quite inexpensive – and be sure to check that it has the same ampacity as the old one. Everybody can DIY breaker replacement; you can consult this guide on how to replace a circuit breaker if you need some help.

Once you have a working breaker again, your AC should stop tripping it.

#2 Wrong AC Wiring (New Air Conditioners Trip Breaker Immediately)

Another possibility, especially for new air conditioners, is wrong wiring. If you have a newly wired thermostat or you have just replaced an old thermostat, chances are that not all wires are connected to the right sockets.

For air conditioners, you will have to connect:

Blue or yellow wire is meant for cooling. These wires are connected to the Y terminal in a standard thermostat.
Red fire for power, connected to R.
Common wire (usually black) connected to C.

wrong thermostat wiring leading to ac breaker tripping

For more advice on how to wire a thermostat, you can consult the thermostat wiring guide here .

Wrong wiring will lead to the outside AC unit tripping breaker immediately (central aircon or mini splits). This is a standard AC compressor tripping issue; the compressor creates a surge of amps that can hit an undersized breaker if it’s wrongly wired.

Solution: Check that all the wires are in the right sockets. In limited cases, you will have to can an electrician to fix this, but most people can use the guide cited above to adequately wire a thermostat themselves.

#3 Electrical Short Circuit (Unsheathed Wires Touching)

Any short circuit can cause a spike in electrical current (amps) that will trip the breaker. In fact, one of the reasons why we use circuit breakers in the first place is to protect our circuits against short circuits.

In the case of wiring air conditioners, the short circuit happens when two exposed wired (unsheathed because the coating has been degrading for years) touch.

Example: Let’s say that the blue and red wire touch. This doesn’t happen if they are properly insulated. However, over time, insulation can decay. When this happens, the electrical current from two wires will travel along a single wire (the one with the least electric resistance, according to Ohm’s law). This will cause a spike in amps that can knock out the breaker.

Admittedly, it’s very difficult to tell if you are experiencing a short circuit. You do have to go to check all the wires to see if the insulation is damaged. This short circuit problem also causes the AC to trip break immediately, after 5 minutes, or even after 10 hours of running the AC unit. It is not time-specific which makes the detection even harder.

Solution: If you suspect that your AC unit tripping the breaker due to a short circuit, you can check the wires yourself or call an electrician. Once you find faulty wires that are causing the short circuit, you have to reapply the coating, or, in more cases, just replace the wire.

All of this, of course, is easier said than done.

Once you have eliminated the thermostat-related problems, you can start checking if there is something wrong with your air conditioner unit, resulting in the breaker tripping repeatedly:

#4 Dirty Condenser Coils (Causing Outside Air Conditioner Circuit Breaker To Trip)

A lot of AC tripping breaker problems are caused by the air conditioner overheating. One of the most common examples of this is the air conditioner circuit breakers outside to trip.

The outdoor condenser coils are exposed to the environment. That means that anything from dirt, leaves, dust, and grass, can find its way into the AC outdoor unit (you may even find a dead rat in there) . If this dirt accumulates on the fairly exposed condenser coils, you will have problems with the outdoor AC unit tripping breaker.

These condenser coils are basically superb heat exchangers . They expel all the heat that is generated in the refrigeration cycle. If these condenser coils are coated with dirt, for example, their ability to conduct heat is impeded. Obviously, if the coils can’t give away enough heat, the whole outdoor unit will get overheated.

And overheating leads to the AC tripping the breaker.

In this case, the AC breaker won’t turn trip immediately. It won’t even trip in 5 minutes or so. Dirty condenser coils are one of the most common reasons why the AC trips breaker after a few hours. The AC will overheat in time and that can take anywhere from some 10 minutes to several hours.

Solution: Clean the outdoor condenser coils. Open the outdoor unit and check if there is dirt coating on the coils. If there is, clean out the debris and spray them with detergent or coil cleaners. You can read how to clean the condenser coils on the Carrier website here .

After the outdoor coils are cleaned, they can adequately exchange heat again. That means that all the heat that has to be expelled via the coils will be released into the atmosphere again. As a result of the AC unit not overheating, you will no longer have a problem with AC breaker tripping.

#5 Dirty Air Filters (Restricted Airflow Results In Overheating And Trips Breaker)

Dirty air filters are another common culprit for an AC unit to trip breaker after a few hours.

We all know that every AC should have adequate airflow. If the filters are dirty, they restrict the airflow. This can cause a series of unwanted issues and will eventually lead to AC overheating. And, as we know, if the AC is overheating, it will inevitably trip a circuit breaker.

Everybody pretty much knows what to do with dirty air filters, right?

Solution: Clean or replace the air filters. This will again enable the AC unit to operate at sufficient airflow. The AC unit will not overheat. The AC breaker will not trip. It’s a pretty simple fix.

#6 Compressor Fails To Start (Or Hard-Starting Compressor)

Out of all the things that may go wrong, the compressor-related issues are the worst. When you have a faulty compressor, you will in almost all cases have to replace it. This replacement can be so costly that homeowners with older units usually just replace the whole air conditioning system.

Now, if you have a faulty compressor (the reason might also be a fault capacitor), you can expect two things to happen:

Compressor doesn’t start at all. Regardless of this, the AC compressor can still trip the breaker. You will notice that in this case, the AC compressor trips the breaker immediately.
Compressor starts slowly (usually takes a few seconds) . This is an indication of a faulty compressor and might lead to the AC compressor tripping the breaker after a few minutes.

The compressor – the main part of the AC – is responsible for compressing the refrigerant gas. If it doesn’t do its job, the AC unit might start overheating and blowing warm (instead of cold) air.

When the compressor doesn’t start at all, there is usually a spike in amps along the compressor wire to the breaker. This will trip the breaker immediately.

If you have a hard-starting compressor, the breaker won’t trip immediately. Nonetheless, such a compressor repeatedly can repeatedly send amp spikes towards the breaker in order to keep running. Eventually – usually in a few minutes or so – one of these amp spikes will overwhelm the circuit breaker and the breaker will flip.

Solution: This is a hard pill to swallow but you will probably have to replace the AC compressor. This is a complex replacement process you can’t do yourself; you will require an HVAC professional to do it for you.

You can, of course, take this ‘opportunity’ to replace the AC unit altogether. If your AC unit is past its prime (15+ years old), replacing the whole air conditioner makes sense in many cases.

#7 Compressor Is Grounded (Wires Touching The Sides)

Another problem a compressor might have – much less troublesome – is some wire displacements. Namely, the electrical wires that power the compressor are unsheathed and touching the compressor casing. It’s always best to check if everything is OK with the compressor wires.

Of course, if the wires touch the metal casing, all that electricity will go to the ground (we talk about the compressor being grounded). Inevitably, this will cause a spike in amps that will knock out the breaker.

Now, this may happen when you turn on the AC, after a few minutes, or even after several hours. The vibrations in the compressor pretty much displace one wire so much that it touches the casing, and that may happen immediately or even after some hours.

Solution: Check if all the wires that go in and out of the compressor still have their insulation coating on them. Also, check if the wires are neatly packed and away from the casing. If you find an exposed wire close to the casing, it’s very likely this is the wire that keeps tripping the AC breaker.

Use a plastic or nylon line to fix the wire in place, away from the casing. You can even replace that wire if you see that the insulation coating is severely damaged. After you do that, your breaker should stop tripping.

#8 Low Refrigerant Levels (Lines Leaking Freon)

All air conditioners work based on the refrigerant cycle. For this cycle to work properly, the lines have to be full of freon (refrigerant gas like R22, R410A, and so on). If you have a leak in the refrigerant lines, there will be less refrigerant within the lines which will lead to AC overheating and potentially tripping the breaker.

Example: If your window AC keeps tripping the breaker, the refrigerant leak could be the culprit.

Solution: You have to check if the refrigerant levels are indeed low by measuring the refrigerant pressure. If freon is indeed leaking out, you will first have to seal the leak and then recharge the AC unit.

In most cases, you will need professional help for this.

If you want to know how a professional refills the freon, you can consult this article about how to recharge a window air conditioner .

#9 Faulty Fan Motor (Leading To Overheating And Breaker Tripping)

In limited cases, we also see that a faulty fan motor is responsible for the outdoor AC unit tripping a breaker after a few hours.

The outdoor fan produces airflow that expels the heat into the environment (cooling the condenser coils). That fan is powered by the motor. If the motor doesn’t produce adequate power output, the fan doesn’t produce adequate airflow, and the outdoor AC cooling process is impeded.

bad fan motor causing air conditioner to trip breaker

This can lead to AC overheating and tripping the AC breaker. This happens when the AC is overheated enough; it takes a few hours (not on start-up or after a few minutes).

Solution: Check if the outdoor fan is spinning. If not, the problem might be a faulty fan motor. You will probably need to replace it. Before you do that, do check out all the reasons why outdoor AC is not spinning here . Namely, a faulty fan motor is not the only reason why the condenser fan is not spinning.

After you fix this and the fan is spinning again, there won’t be overheating, and the outdoor AC unit will stop tripping the breaker.

How To Call If You Need Professional Help?

As we have seen, both the diagnosis of why the AC keeps tripping the breaker as well as the fixes are not a piece of the case.

From checking the breaker to checking if something is wrong with your AC unit, there is quite a lot of knowledge (and experience) that guys fixing AC units should have.

This article was a general overview of the causes for AC to keep tripping the breaker. If, however, you realize you will a professional help, you can turn to your local HVAC companies.

We hope this helps somebody figure out why the AC keeps tripping the breaker and how to go about fixing it by themselves or with professional help.

“My AC Works But It Keeps Tripping the Breaker”

Does your air conditioner cool for a while but then trip your circuit breaker and shut off?

Typically, your AC breaker trips when there’s a short circuit, the AC is overworking or a part is bad or malfunctioning.

If you continue to run your AC, you could permanently damage the air conditioner. Get a professional AC repair tech out as soon as you can.

Now let’s look at the specific causes of an AC tripping the breaker.

Specific AC problems that can trip your breaker

Dirty air filter.

If you leave your air filter in so long that it is completely clogged with dirt, it can suffocate your AC, causing it to work much harder than it should, overheat, and trip the breaker.

Dirty condenser coils

These coils, located in the outside AC unit, are designed to release the heat from your home to the outside. But if they’re covered in dirt, they can’t do that. (It’s like you trying to cool off while wearing a wool sweater).

Bad capacitor

A capacitor is responsible for starting and keeping your air conditioner running. If it goes bad, it can pull too much electricity and trip your breaker.

Old or weak compressor

The compressor is in your air conditioner’s outdoor unit. A weak compressor has trouble starting. When it does try to start, it may try to pull too much electricity, which will trip your breaker.

If this is the problem, an air conditioning professional might recommend installing a hard start kit.

Loose electrical connections

Wires expand and contract as the weather changes, which can cause loose electrical connections inside of your air conditioner and result in a short circuit.

Another mechanical problem

There are numerous small mechanical problems that could also be causing your AC to trip your breaker.

AC Breaker Keeps Tripping? Here’s What You Need to Know for a Quick Fix

We know this can be a bothersome problem, but we’re here to help you get it sorted out quickly and easily. An AC breaker that trips often is usually caused by an issue with your circuit wiring or by a malfunctioning appliance.

If your AC circuit breaker keeps tripping, there are several potential reasons.

Identifying the source of the issue before attempting any repairs is essential. Once you’ve identified the source of the problem, we’ll explain how to take care of it in just a few simple steps. If your AC breaker keeps tripping and you’re looking for a quick and easy fix, this article is for you!

What Is an AC Breaker?

An AC Breaker is a crucial safety feature in your home’s electrical systems that helps protect against overloads and short circuits. It works by breaking the circuit and cutting off electricity when it senses an overloaded or short-circuited wire.

You can find these devices in your main electrical panel, as well as individual outlets and switch boxes throughout your home – making sure that you and your family are always safe from harm.

The AC breaker consists of two parts: a circuit breaker switch and a trip indicator. The circuit breaker switch is responsible for cutting off power when it detects an overload or short circuit – this prevents further damage to your wiring and appliances.

The trip indicator shows whether the breaker has been tripped, allowing you to reset it if necessary.

Why Do AC Breakers Trip?

If your AC keeps tripping the breaker, the most common causes are either too much current being drawn from one circuit or a short circuit caused by faulty wiring or a damaged appliance.

If any of these conditions are present, it can cause the breaker to trip and shut off the power to that area of your home.

Other potential causes include a failed motor or compressor in your air conditioner or even dust accumulation on the breakers themselves.

What To Do When Your AC Breaker Trips

Is your AC tripping the breaker? It can be an annoying and inconvenient issue to deal with. But don’t panic – there are a few simple steps you can take to try and fix the problem.

Check your air conditioner’s filter. A clogged filter can cause the breaker to trip by overloading the circuit. Replace or clean it if needed.

Look for any signs of damage on the wiring leading up to the AC unit. If the wiring looks frayed or damaged in any way, call a licensed electrician for help as soon as possible.

If none of these solutions work, it might be time to upgrade your electrical panel or have an electrician install a higher-capacity breaker specifically designed for your air conditioning system. By taking these steps now, you can avoid costly repair bills down the road and get back to feeling comfortable in no time!

Common Causes of AC Breakers Tripping

There are many possible reasons why your AC unit keeps tripping the breaker. Below, we’ll take a look at some of the most common.

A Dirty Air Filter

One of the most common causes of an AC breaker tripping is a dirty air filter. When an air filter becomes clogged with debris, it can cause your system to work harder than it needs to and eventually trip the breaker.

You’ll want to ensure you regularly check and replace your air filters to keep them clean and functioning properly.

Dirty Condenser Coils

Another potential culprit for a tripped AC breaker is dirty condenser coils . These coils are responsible for releasing heat from the system, so if they become covered in dirt or other debris, they won’t function as efficiently and could potentially cause your breaker to trip.

Make sure you routinely inspect and clean your condenser coils for optimal performance. If your AC trips the breaker after 5 minutes of working, this is a possible cause.

Broken Coil Fan

A broken coil fan could also be causing your AC’s breaker to trip. The fan helps circulate cool air throughout the room, but when it stops working properly, this disruption can put a strain on the system and cause it to trip the breaker as a safety measure.

If you suspect that your coil fan may be malfunctioning, contact an HVAC technician right away so they can diagnose the issue and repair any damages quickly.

Problematic Compressor Start-up

One of the more common causes of an AC breaker tripping is a problematic compressor start-up . If your compressor is having trouble starting up, it can draw too much current and cause the breaker to trip. This problem is usually caused by faulty wiring or parts, such as a capacitor or motor winding.

Loose Wiring or Faulty Parts

Loose wiring or faulty parts are also frequent culprits behind AC breakers tripping. Loose connections can create dangerous arcs that will cause the breaker to trip.

Additionally, if some internal part in your AC unit has become damaged and isn’t working properly, it could also lead to an overload that trips the breaker.

Too Little Refrigerant

Another common reason for AC breakers tripping is too little refrigerant in the system. This can happen when there’s a leak in the system somewhere, which causes the refrigerant levels to drop below the required amount for your AC unit to work properly.

When this happens, your unit will have difficulty cooling down and not be able to handle large loads efficiently—causing it to trip its own breaker as a safety measure.

The Compressor Is Grounded

If your AC’s compressor is grounded, then it could be the cause of your breaker tripping. This can happen if a wire becomes loose or disconnected or if the wiring around the compressor has been damaged due to corrosion or wear and tear.

To check for this issue, you should inspect the wiring and connections around the compressor. If all looks okay, you’ll need to call in a professional to take a closer look.

The Evaporator Coil Is Frozen

Another common cause of an AC breaker tripping is a frozen evaporator coil . This occurs when air isn’t flowing properly through the unit, and as such, causes an overload on the system, which trips the breaker switch.

To fix this issue, you’ll need to clear any blockages from your AC vents so that airflow can be restored. You may also need to replace any broken parts inside your unit for optimal performance and safety.

The Circuit Breaker Is Faulty

If your AC circuit breaker keeps tripping, it’s possible that your circuit breaker itself is faulty and needs replacing in order for it to operate correctly again. A qualified electrician will be able to diagnose whether this is an issue by testing the circuit breaker for any signs of wear or damage.

A qualified technician can accurately diagnose why your AC circuit breaker keeps tripping.

If you do find yourself needing a new one, ensure to get one with an appropriate amperage rating that matches up with your home’s electrical system requirements!

While the steps listed above are excellent ways to identify why your AC breaker keeps tripping, we wouldn’t recommend working with electricity without some form of training. The problems are often relatively minor, but the risks involved when working with electricity simply aren’t worth it to save a few bucks.

The bottom line is that if your AC breaker keeps tripping, the best thing to do is to call a qualified AC technician for help. An experienced technician can diagnose why your AC breaker keeps tripping and then take steps to ensure it doesn’t happen again.

While it may seem like a hassle, having your AC breaker checked out by an expert can help you avoid costly repairs down the road. Safety should always come first when dealing with electricity – so don’t take any chances!

Why Is My AC Tripping the Circuit Breaker?

October 04, 2021

Air conditioners are vital to Floridians, so it's no surprise that homeowners would be stressed if their AC suddenly started turning off.

If this is happening to you now, it’s likely a tripped circuit breaker. When your AC trips the circuit breaker after running for only a few minutes, your breaker cuts the power to the AC system.

Why is your AC tripping the circuit breaker? Many issues can be at play, but the primary 3 reasons include:

An overloaded circuit
A grounded compressor
A faulty breaker

We’ll review how to reset your circuit breaker to see if that restores your AC’s power. If it doesn’t, we’ll dive into the potential problems related to a tripped circuit breaker and how to troubleshoot them.

Reset your circuit breaker

Reset your circuit breaker to see if it stops tripping

Before we look at what could be causing the frequent tripping, let's first try resetting the circuit breaker. You can do so by:

Let the unit cool down for about 5 minutes. The Department of Energy recommends letting the unit rest before resetting any breakers.
Turn off your thermostat.
Locate your gray main circuit panel by checking your closets, garage, or basement. Make sure there's no water on the ground in the room with the panel. If there is, do NOT stand in the water while resetting the breaker.
Find the AC switch. The breakers are typically labeled. If not, look for the switch that is either in a middle position or OFF. Some manufacturers have a visible color indicator that shows that a breaker has tripped.
Push the switch OFF unless it's already OFF. If already OFF, skip to Step #6.
Push the switch ON. You should feel a satisfying click into place.
Wait for 30 seconds.
Turn your AC back on to test.

If your AC immediately trips again, do NOT reset the breaker again until the cause is corrected. Multiple overcurrents, or surges of electricity, can damage your AC and even start a fire.

Read on to learn about the potential issues causing your AC to trip the circuit breaker.

Three main reasons behind your AC tripping the circuit breaker:

1. an overloaded circuit.

Circuit breakers shut off the flow of electricity whenever the number of amps (a unit of electrical current) exceeds its amp rating. For example, if the circuit breaker has a rating of 15 amps, it'll trip whenever 20 amps flow through the circuit.

So, whenever your AC is using too much energy, it's pulling in more amps than usual, causing a surge and your circuit breaker to trip.

Your air conditioner can use too much energy if:

The air filter is dirty:

An Advanced Air technician can help you replace your filter

Air conditioners need air to be flowing into the system to cool your home enough to meet your set temperature.

When air filters get clogged with debris and dirt, they block airflow from entering the system. Your AC now has to compensate by working harder and using more electricity to cool your home. The circuit breaker isn’t used to this amount of energy consumption and trips to protect your AC.

The condenser is dirty:

Our technicians can help clean your condenser

Your AC's outdoor unit is called the condenser. It plays an essential role in keeping your home cool by dumping the heat your indoor unit absorbs from your home's air outside.

When the condenser is dirty or blocked by bushes, your outdoor unit can no longer effectively transfer the heat outside, and your AC has to use more energy and take longer to cool your home. This increase in needed power trips the circuit breaker.

The condenser fan doesn't work correctly:

As we mentioned above, the condenser is your outdoor AC unit. The condenser's fan helps dissipate heat back outside. If you stand next to the condenser and can't hear the fan rumbling, it's likely broken.

When the fan’s motor is broken or worn out, the electricity from your AC system to the motor has nowhere to go and is flowing freely. Your AC will automatically detect this issue and trip your circuit breaker to prevent the wires from frying and damaging your system or home.

The refrigerant is leaking:

What is refrigerant? It's a cold substance in your AC that helps the indoor unit absorb heat from the air. Leaking refrigerant means your AC can't cool your home as effectively due to reduced heat absorption abilities, forcing it to use more power and tripping the breaker due to overload.

How do you know you have a refrigerant leak? You can tell when:

You see ice forming on the condenser
You hear hissing or bubbling noises coming from your inside AC unit
You have higher than normal monthly energy bills

Advanced Air technicians can diagnose the problem behind your circuit tripping

If you suspect your breaker keeps tripping because of any of these reasons, try changing out your air filter monthly and booking an appointment with an AC technician to clean the condenser. Also, make sure to check your condenser's fan and inspect the refrigerant lines.

2. A shorted compressor

Typically, electricity flows in a loop called a circuit. When a compressor "shorts," it's because a malfunction interrupts the loop, allowing too much electricity to flow through the circuit. The circuit breaker then trips to shut off electricity to prevent the overload from potentially causing a fire.

Most malfunctions are because of a winding, where electrical currents pass through inside the compressor, breaking and not being able to handle its load anymore. The additional electricity ignites the oil in the compressor, causing a sudden current surge that burns out the compressor and forces the circuit breaker to trip.

Unfortunately, a burned-out compressor most likely needs to be replaced because a functional compressor is vital as it pumps refrigerant throughout your system.

Replacing the compressor can be expensive if you don't have a valid warranty. If you have a valid warranty, financing options can help. Or, you might want to look into replacing your system entirely. You can use our handy AC installation cost calculator to see if a replacement would be more cost-effective than replacing your compressor.

3. A faulty breaker

A damaged circuit breaker

Your circuit breaker may keep tripping because of an issue with the breaker itself.

To determine if the breaker is damaged, find your home's main circuit panel and look for indicators that you have a faulty breaker, such as:

The breaker is hot when you touch it
You can smell a burning odor near the breaker
You see loose connecting wires
You see burn marks on the breaker
You see obvious worn-out parts

If you notice any of the above indicators, you're dealing with a faulty breaker that needs professional replacement. Call a technician immediately.

My AC Breaker Keeps Tripping: Common Culprits and How to Fix It

If your AC breaker keeps tripping, it can be a frustrating and confusing problem. If your air conditioner is tripping the breaker, there can be a range of issues behind it, such as a dirty air filter, dirty condenser coils, fan damage in the outdoor unit, a faulty compressor, damaged or loose electrical wiring, or a bad circuit breaker.

You might not know what’s wrong with your AC circuit breaker or how to fix it. Don’t worry – we’re here to help! The Cincinnati air conditioning repair experts at Thomas & Galbraith Heating, Cooling & Plumbing team will explain what an AC circuit breaker is and why the breaker trips. We’ll also share how to troubleshoot certain issues that may be tripping the breaker and when to call an HVAC professional to fix AC units.

What Is the Air Conditioner’s Circuit Breaker?

A circuit breaker is an electrical switch that automatically turns off when the current flowing through it becomes too strong. This prevents damage to the circuit by preventing it from overheating. Circuit breakers can be found in homes, businesses, and industrial facilities.

They are typically located in the main electrical panel, which is typically located in the basement or garage. Circuit breakers come in a variety of sizes and amperages, and they can be either single-pole or double-pole. Single-pole circuit breakers are typically used for small appliances such as toasters and hair dryers, while double-pole circuit breakers are typically used for larger appliances such as ovens and air conditioners .

When choosing a circuit breaker, it is important to select one that is rated for the amperage of the circuit it will be protecting. For example, a 20-amp circuit should be protected by a 20-amp breaker.

Circuit breakers can trip for a variety of reasons, including overloads, shorts, and ground faults. If a circuit breaker trips frequently, it may be an indication that the circuit is overloaded and needs to be replaced with a larger one. Short circuits occur when there is an accidental connection between the hot wire and the neutral wire.

Ground faults occur when there is an accidental connection between the hot wire and the ground wire. Both of these conditions can cause overheating and damage to the circuit breaker, so it is important to have them repaired as soon as possible.

Why Your Air Conditioner Circuit Breaker May Trip

A circuit breaker is designed to trip and cut off the power when it senses an overload on the circuit. This is a safety feature that protects the wiring from overheating and starting a fire.

However, if the circuit breaker is faulty, it may trip even when there is no overload. This can be frustrating, especially if it happens on a hot day when you are trying to use your air conditioner. Here are some of the common reasons your air conditioner may be tripping the circuit breaker.

Dirty Filter in the AC System

A common cause of the air conditioner circuit breaker tripping is dirty air filters. The air filter helps to remove dirt, dust, and other airborne particles from the air as it circulates through the system. Over time, the filter can become clogged with debris, making it harder for air to flow freely. As a result, the air conditioner has to work harder to cool the home, causing a rise in electricity usage. This increase in electricity usage can cause the circuit breaker to trip, disrupting the flow of power to the system.

If your air conditioner’s circuit breaker is tripping, the first thing you should check is the filter and install a new AC filter if needed. To do this, simply locate the filter (it’s usually behind a grate on the front of the unit), remove it, and put in a new one. Once you’ve done this, turn the AC back on and see if the problem has been resolved. If the circuit breaker still trips, you may have a bigger issue that will require a professional to take a look at.

To avoid this problem, it is important to regularly clean or replace the air filter. By doing so, you can help keep your air conditioner running smoothly and prevent unnecessary circuit breakages.

Dirty Condenser Coils Tripping the Circuit Breaker

One of the most common reasons for an air conditioner circuit breaker to trip is dirty condenser coils. As the coils become clogged with dirt and dust, they become less effective at transferring heat. This causes the coils to overheat, which eventually trips the breaker. In addition, dirt and debris can also block airflow through the coils, causing the compressor to overheat.

If you notice that your air conditioner’s circuit breaker is tripping more frequently, it’s a good idea to have the coils cleaned by a professional. The condenser coils are often cleaned as part of a professional maintenance tune-up for your air conditioning unit, so make sure to schedule these each year to prevent circuit breaker problems caused by the condensing coil in the outside AC unit. With regular maintenance, you can help keep your air conditioner running efficiently and avoid costly repairs down the road.

Fan Problems in the Outdoor Unit

A broken coil fan in the outdoor unit can cause the air conditioner circuit breaker to trip for a few reasons. First, the fan is responsible for circulating air over the coils. Without the fan, the coils can’t do their job properly, and the air conditioner will overheat. Second, a broken fan can cause the coils to freeze up, which will also cause the air conditioner to overheat. Finally, a broken fan can cause the compressor to overheat, which is another reason why the air conditioner will trip the circuit breaker.

Sometimes, the fan blades may be causing the issue. Check the blades to make sure they are not damaged or obstructed. If there is debris blocking the condenser fan, turn off the power source to the air conditioner first, then carefully remove the material.

If the fan blades are damaged, or the problem seems to be due to the fan motor or other component, it’s time to call an AC tech for repairs. A broken coil fan in the outdoor unit is a serious problem that can cause the air conditioner to trip the circuit breaker. If you suspect that your fan is broken, it’s important to call a qualified technician for help.

Air Conditioner Tripping Due to Compressor Failure

Another one of the of the most common reasons why an air conditioner trips the circuit is because of a faulty compressor. The compressor is responsible for circulating refrigerant throughout the AC unit, and if it isn’t working properly, it can cause the unit to overheat. In some cases, the compressor may even start to leak refrigerant, which can be dangerous. If you notice that your air conditioner is tripping the circuit more frequently or if it’s starting to make strange noises, it’s important to have a professional take a look at it. Otherwise, you could end up damaging your AC unit beyond repair.

If you have an old AC unit, it may not be able to handle the increased load and will trip the circuit. In older models, the contactor closes with a spring-loaded plunger. The dust and dirt can cause the contact points to become corroded over time, which makes it harder for the contactor to close. This can cause arcing and eventually burning out the contactor. A failed or damaged capacitor will need to be replaced in order to get your air conditioner unit working properly again. Replacing a worn-out or damaged contactor is an inexpensive repair that can prolong the life of your air conditioner unit.

It may be necessary to install a hard start kit for your air conditioning compressor. A hard start kit helps to amperage the low voltage so the compressor can start with less strain. The capacitor provides a boost of energy so that the compressor can overcome any resistance and get started.

Bad Circuit Breaker or Loose Wiring to the Air Conditioning System

One of the most common reasons an air conditioner trips is because of a bad breaker. The breaker is what controls the flow of electricity to the air conditioner, and if it is not working properly, it can cause the air conditioner to trip. A bad breaker can be caused by a variety of things, including a loose wire or a problem with the breaker itself.

If you think your air conditioner has tripped because of a bad breaker, the first thing you should do is check the breaker to see if it is loose or damaged. If the breaker is loose, you will need to tighten it. If the breaker is damaged, you will need to replace it. You can usually find replacement breakers at your local hardware store.

If the wires are not properly connected, they can overheat and cause the circuit to trip. In some cases, the wires may also short-circuit, causing an electrical fire. If you suspect that your air conditioner’s wiring is to blame for its circuit problems, it’s important to have a professional electrician take a look at it as soon as possible. Otherwise, you could be putting your home at risk of serious damage.

Why Does My Air Conditioner Keep Tripping the Circuit Breaker?

There’s nothing more frustrating than coming inside to beat the scorching summer heat, only for your air conditioner to abruptly shut off – again and again. You reset the tripped circuit breaker hoping for relief, but it keeps tripping minutes later, leaving you melting in the sweltering temps. This cooling crisis doesn’t just ruin your comfort, it can seriously damage your HVAC system if the underlying problem isn’t resolved quickly.

Before you find yourself stuck sweating it out, understanding why air conditioners repeatedly trip breakers is key. This guide dives into the most common offenders behind this maddening issue. From electrical faults and blocked airflow to frozen components and undersized units maxed out under extreme loads – several potential culprits could be forcing your AC into that breaker-tripping loop.

We’ll walk through diagnostic steps to identify what’s happening, plus preventative tips to avoid cooling interruptions during the peak heat months. Don’t suffer through an indoor sauna – get that air conditioner reliably running again by tackling the core issue head-on. Reclaim that refreshing chill your home deserves.

Understanding Circuit Breakers

To get why your AC keeps cutting power, you first need to know how circuit breakers operate. These small switch devices automatically break a circuit when the electrical current gets too high – shutting things off before overloads can spark bigger issues.

Take a peek at your home’s electrical panel. You’ll see rows of breakers there, each one controlling power flow to a different room, outlet, or hardwired appliance like your air conditioner. Every breaker has an amp rating showing the maximum current that a particular circuit can handle safely before the switch flips and kills juice as a precaution.

Air conditioners are bigger power hogs, so they need hefty dedicated circuits with higher amp ratings – typically 30 amps or more depending on AC size. When too many amps try forcing their way through, it causes that breaker to trip and shut off the unit.

The usual culprit? The AC is simply drawing more electrical current than that circuit can provide, resulting in an overload scenario. But breakers also trip due to short circuits, ground faults, arcing problems, and other electrical gremlins that enable excessive current flows.

While losing power may seem like a hassle, that tripped breaker is actually doing you a favor by cutting things off before potential fire risks or equipment damage occurs. If you keep experiencing nuisance trips though, it means there’s an underlying issue that needs professional diagnosis and repairs ASAP.

Common Reasons Why ACs Trip Circuit Breakers

Sure, your AC’s circuit breaker serves an important safety role by cutting power before electrical overloads can spark real dangers. But when that breaker keeps tripping over and over, it points to an underlying issue you can’t just keep brushing off. From airflow restrictions and refrigerant problems to faulty components and inadequate circuits – several common culprits could be repeatedly forcing your cooling system into that overload territory.

Overloaded Circuit

This one’s the most obvious – your AC unit is simply demanding more electrical current than that circuit can consistently provide. Trying to force too many amps through undersized or aging wiring creates a classic overload scenario that triggers breaker trips as a preventative measure. Undersized conductors, loose connections reducing current capacity, and running too many high-draw appliances on the same circuit can all contribute.

Dirty Air Filters

It’s amazing how much strain accumulating dust and gunk can place on your AC system over time. When air filters become clogged, it restricts airflow through the indoor unit – obstructing that critical heat transfer process from happening efficiently. With less cool air circulation, components like the blower fan motor end up working overtime, drawing excessive electrical current that can quickly overload circuits.

Refrigerant Leaks

refrigerant is the lifeblood enabling your whole air conditioning cycle to transport thermal energy out of your home’s interior. When leaks develop, refrigerant levels drop – making the whole system work a lot harder to achieve the same cooling output. Those diminishing returns translate into increased electrical consumption and higher current draws that can overload breakers. Recharging and sealing leaks resolve the excess amperage issue.

Blocked Condenser Coils

Over in the outdoor condenser unit, those coils play a vital role in rejecting absorbed thermal energy outdoors. But when dust, grass clippings, shrubbery, or other debris accumulates around those coils, it obstructs airflow – dramatically reducing heat dissipation efficiency. Just like on the indoor side, those blocked coils force your AC system to work harder, drawing more amps until circuits become overwhelmed.

Faulty Capacitors

On the electrical side, capacitors act like temporary power reserves – providing torque to get hardworking compressor and condenser fan motors spinning those heavy-duty components when first starting up. When capacitors degrade or fail, those motors struggle to turn over properly which creates massive current spikes capable of overwhelming circuits instantly. Replacing worn out capacitors eliminates another potential breaker trip trigger.

Short Circuits

One of the scarier electrical gremlins that can force breakers into bodyguard mode? Short circuits – when hot wires accidentally make contact with neutral conductors or grounding sources. This abnormal low-resistance connection allows intense current surges to overwhelm circuits in a split second before breakers can react. Damaged wiring insulation, loose terminals, and exposed conductors enable these direct short-circuit paths to form.

Motor Issues

Those energy-guzzling compressor and fan motors are the real workhorses powering your AC through those critical cooling cycles. But when motor bearings wear down or windings short out, it creates internal friction that demands excess current to maintain operation. Add in decades of insulation breakdown and you’ve got a recipe for AC motor faults capable of easily overloading circuits until that breaker pulls the plug.

Loose Electrical Connections

Speaking of loose terminals, these create another current overconsumption headache by generating excessive heat at connection points. As conductors oxidize over time and connections loosen up, more resistance increases current demands. Those hot spots elevate fire risks too if left unresolved. Periodically tightening terminals and cleaning connections eliminates one more potential breaker trip trigger.

Grounded Compressor

Here’s an odd one – if your AC’s compressor motor accidentally gets grounded to its housing, it can enable stray current to flow through that unintended ground path. Not only does this increase current draw on circuits, but it also energizes exterior metal components creating a shocking safety hazard! Severed or damaged insulation between motor windings and the compressor shell usually allows these grounding faults.

Thermostat Problems

That humble wall-mounted thermostat may seem like an unlikely suspect for breaker trip episodes. But if that thermal sensor mistakenly reads inaccurate temperatures, it can continuously signal your system to run when it shouldn’t – overworking parts until circuits become overwhelmed. Thermostats can also electrically short out or develop software glitches similarly enabling those constant cooling mode commands.

Clogged Air Ducts

Don’t just consider filter buildup – the ductwork circulating all that cooled air can get obstructed too. Over years of dust accumulation, dents from household renovations, or critter invasions, those air ducts can become significantly blocked. Restricted airflow has the same impact as clogged filters – forcing blowers and condensers to labor harder drawing excess current until breakers throw in the towel.

Undersized Circuit Breaker

Alternatively, sometimes the breaker itself winds up underrated for an AC’s actual electrical demands. Homes expand over decades with extra rooms or appliances added to circuits not originally designed for those loads. If you’ve got an older home with too small a breaker protecting that now-oversized cooling system, nuisance trips become inevitable until an electrician resizes it appropriately.

Electrical Overload from Other Appliances

Remember, that circuit breaker doesn’t just protect your AC – it handles current loads from every outlet, light fixture, and device operating on that same branch circuit. Running too many high-wattage appliances like space heaters, ovens, and dryers simultaneously in addition to your cooling system can max out even properly sized breakers.

Old or Worn-Out AC Unit

At a certain point, even the best-maintained air conditioners simply reach the end of their expected service life. As compressors deteriorate, insulation breaks down, and parts like capacitors degrade over a decade or more, their energy inefficiency continually rises. An aging AC gradually draws more amps every season until even properly rated breakers give out regularly.

Fan Problems

Don’t overlook those crucial blower and condenser fans! When their motors start failing, blades get obstructed, or fan speeds reduce from slippage or control issues, it demolishes overall system airflow and heat dissipation. Just like clogged filters, the diminished airflow increases amperage demands across multiple components until the excessive current consumption hits a breaking point.

From electrical hazards and mechanical breakdowns to airflow restrictions and refrigerant problems – a variety of AC system failures can create current consumption levels high enough to persistently trip circuit breakers. Identifying the root cause requires close inspection, as every unnecessary breaker trip increases fire risks while wearing down components faster. Don’t ignore those persistent power interruptions!

Diagnosing the Problem

Sure, that tripped circuit breaker may just be an annoyance forcing you to go reset it over and over. But brushing off those persistent power interruptions as a mere inconvenience could be putting you and your home at serious risk. Underlying issues like electrical hazards, mechanical failures, and airflow obstructions frequently hide behind repetitive breaker trips.

Rather than just kicking that AC back on and hoping for the best, you need to play detective and get to the root of what’s causing those dangerous overload conditions in the first place. Left unchecked, excessive current consumption drastically increases fire risks and accelerated component wear. Solving the head-scratcher is the only way to reliably restore safe system operation.

Start With the Simple Stuff

Like any good investigation, begin by eliminating the easy potential culprits first before moving onto more complex scenarios. Thermostat glitches providing faulty run signals or incorrect programming represent a good starting point to check.

Next, closely inspect all accessible components and air pathways searching for obvious obstructions or damage. Clogged filters, coils caked in dirt/debris, or bent fan blades could be strangling airflow and forcing that AC into overdrive. Check electrical connections too – tightening any loose terminals or cleaning oxidized surfaces may already reduce resistance cutting current demands down.

Monitor for Recurring Issues

Assuming no glaring issues jump out, you’ll need to keep a vigilant eye out for patterns spotlighting when those breaker trips tend to occur. Is it only happening during peak afternoon heat when cooling demands max out? Or after the system runs for extended periods? Consistent times could indicate heat-related failures or overworked components.

Inspecting that outdoor condenser unit while paying close attention to potential hot spots along the refrigerant line set can also yield clues about capacity issues or airflow restrictions externally. And don’t underestimate the power of sound – any abnormal whirs, rattles, or buzzes from blower motors, compressors or other mechanicals could preempt potential breakdowns too.

When to Call a Professional

For the avid DIYer comfortable with basic AC maintenance like filter changes and cleaning coils, those preliminary diagnostic steps provide a solid starting point for pinpointing breaker trip culprits. There are limits though to what homeowners can safely check themselves without proper training or equipment.

If your hunting turns up any suspected issues with the electrical system, capacitors, refrigerant lines or compressor, it’s time to call in a certified HVAC professional. These technicians carry the expertise and specialized tools like multimeters to accurately troubleshoot those complex potential problems lurking behind circuit breaker failures.

The same applies if your preliminary inspections simply turn up zero conclusive evidence – an experienced set of eyes can frequently identify obscure issues you may easily miss. With the number of potential hazards from fire risks to fatal shocks, trusting the real diagnostic heavy lifting to licensed pros ensures your family’s safety and proper system fixes.

An ounce of prevention through diligent maintenance and monitoring pays major dividends in avoiding those disruptive breaker trips to begin with. But when they do occur repeatedly, thorough diligent diagnosis represents the only way to accurately find effective resolutions – rather than just Band-Aid temporary patches creating bigger future headaches. Don’t let underlying problems fester!

Preventive Measures

An ounce of prevention is worth a pound of cure – and that saying definitely applies when avoiding nuisance AC circuit breaker trips. While troubleshooting overload conditions is step one, implementing some preventative best practices provides the best defense against future power interruptions.

Even a well-maintained cooling system cycles electrical loads hundreds of times per season. That constant operation coupled with extreme outdoor temps pushes components to their limits. It’s only a matter of “when” not “if” excessive current demands or electrical faults occur without proper preemptive care. Catching small issues early prevents bigger hassles down the road.

Routine Professional Tune-Ups

Having your system professionally serviced annually should be preventative measure #1. These tune-ups by certified HVAC techs allow for thorough inspections, testing, cleaning, and recalibrations to identify and resolve any budding failures before triggering breaker overloads. The meticulous process covers filter replacements, coil cleanings, refrigerant checks, electrical tests, thermostat calibrations, and more. While an investment, it’s marginal compared to total system replacement costs.

Airflow Vigilance

Maximizing airflow is crucial. Check filters monthly, swapping them when dirty. Use vacuums and rags to clear dust and debris around indoor/outdoor coil fins and blowers. Consider coil cleaner products for stubborn gunk. Keep vents and ductwork clear of obstructions like furniture, toys, or pet accessories too.

Monitor Energy Usage

Watch for rising utility bills signaling developing electrical issues increasing current demands. Consider an energy monitoring tool tracking real-time power draw data to catch spiking wattage demands early before breakers get overwhelmed.

Being proactive about maintenance and monitoring AC energy use enables preemptive repairs before persistent inefficiency causes disruptions. Don’t burn money reacting to emergencies!

Telltale Signs of a Bad Breaker

The first response to a tripped AC breaker is always an attempt to reset it. Inspect your breaker before and as you reset it to check for telltale signs of damage or fault.

Look for the following bad breaker symptoms:

Unusually hot to touch
A burning smell inside the box or panel
Visible signs of damage
It won’t stay in the ‘on’ position

A faulty breaker will trip again, sooner or later, and not necessarily due to an AC problem. When in doubt, contact an electrician and get the breaker inspected, then replaced if necessary.

Don’t attempt anything by yourself if you are not trained or experienced in dealing with circuit breakers.

In most scenarios, the causal problem is a failure or malfunction of one or more significant components of the air conditioner.

However, something as simple as a dirty and clogged air filter can trigger the trip in some cases. Ideally, you should conduct a comprehensive inspection of your air conditioner.

2. Clean the Air Conditioner

Two common reasons why an AC trips the breaker are clogged air filters and dirty coils.

Dirty air filters, condenser coils, and evaporator coils reduce the efficiency of an air conditioner and increase the load. Thus, an air conditioner draws more power than usual. Also, a dirty system leads to overheating of the appliance components.

Any power surge that is beyond the permitted threshold per the circuit breaker will trip it. Clean the air filters. Besides, an unclean air conditioner may intermittently shut down and restart, a process known as short cycling ( source ).

Replace the air filters if necessary. You may need a technician to clean the condenser and evaporator coils.

3. Ensure Essential Maintenance

A standard air conditioner has numerous electrical and mechanical components. All these electrical and moving parts must function flawlessly for optimum performance.

Poor, delayed, or lack of maintenance leads to problems in the following AC components:

Electrical connections, including wiring
Mechanical moving parts, including blower motor and fan blade
Coils and the condensate drain line
Safety devices
Refrigerant/coolant

Source: Amana: Preventive Maintenance

Some contemporary air conditioners have smart thermostats. Thus, the software needs firmware updates, too, for expected thermostat performance.

Thorough maintenance should include a complete cleaning, duct inspection, testing all safety systems in the air conditioner and related wiring, and servicing both outdoor and indoor units.

An air conditioner tripping the breaker frequently could be due to:

Loose wiring
Shorts and grounding issues
Failing electrical components
Fan/blower motor problems
Low or leaking refrigerant
Frozen evaporator coil
Malfunctioning compressor

You can detect and even preempt these common problems through timely maintenance. Many of these issues are averted with preventive maintenance that most service providers usually ensure.

Failing or malfunctioning AC components don’t necessarily need extensive repairs or replacement. Many glitches can be fixed by maintenance and service technicians.

4. Replace Old Air Filters

Cleaning dirty and clogged air filters may not solve the tripping problem if they are too old or worn out. All air filters have a lifespan. 1 inch (25.4 mm) filters usually last well for up to 3 months.

However, many technicians recommend a replacement every 45 days. 4 inches (101.6 mm) filters can last longer. Yet, standard recommendations are to replace them in around 3 to 6 months. Media filters can last up to 1 year. Fiberglass filters don’t perform well beyond 30 days ( source ).

Check the air filter type and size in your air conditioner and abide by the brand’s recommendation.

Old air filters may still work, but they will reduce the efficiency of the air conditioner. Hence, the outdoor air conditioner and the indoor air-handling unit will consume more power and bear a greater load for cooling and circulation at the same or usual thermostat setting.

The increased load and energy consumption may cause a power surge. The air conditioner circuit breaker will flip to neutral if the surge is beyond the trip unit.

5. Fix Compressor Hard-Starts

All air conditioners require a necessary starting wattage to begin functioning.

The starting wattage is usually 2 to 3 times the running watts. A 10,000 BTU central air conditioner can function optimally at a running wattage of 1,500. However, the system needs 4,500 starting watts at the outset ( source ).

An air conditioner compressor has a hard start in the absence of the required starting watts. A few factors can affect the availability of the low starting wattage.

You may have a voltage problem in your power supply.
The capacitor in the compressor may fail or malfunction.
The air conditioner may have failing or damaged motors.
Shorts and grounding issues may also cause a hard start.

A compressor makes unusual noises during a hard start. You may hear a click or stuttering. Many compressors fail to start properly and shut down soon after you turn it on. A hard start is generally the problem in such cases.

If your air conditioner trips the breaker the moment you turn it on, you can almost conclude the problem is a compressor hard start. Other than the components inside and low voltage, the compressor itself could be failing ( source ). You need a technician to conduct a thorough inspection.

An expert will study the problem and tell you whether you can get the hard start problem fixed or the only solution is replacing the compressor.

You may consider hard start kits to increase the voltage.
Consider repairing the wiring and motor problems or replacing the malfunctioning parts.
Replacing an entire compressor is expensive but unavoidable in some cases.

Don’t attempt any of these without a technician unless you are familiar with such repairs and replacements.

6. Resolve Shorts

An air conditioner can have a short circuit. A short will almost always trip a circuit breaker unless the latter is damaged or broken.

The only purpose of a breaker is to protect you, everyone, and everything at your home from a power surge and short circuit, thus preventing an electrical hazard and fire.

Source: National Renewable Energy Laboratory

The common causes of a short circuit involving an air conditioner are:

Faulty or poor wiring in a circuit
Faulty wiring of the air conditioner
Loose electrical connections
Manufacturing defects in the air conditioner
Failing wires and electrical or mechanical components
Grounding issues or broken ground-fault circuit interrupter

Wires can wear out due to overuse. Air-conditioners operating for long hours may lead to wires losing their insulation, leading to electrical leakage. If any conductive element comes in contact with the leaking electricity, you will have a short circuit, and the breaker will trip.

Find out and address the specific problem in the air conditioner, wiring, circuit, electrical and mechanical components, grounding, and ground-fault circuit interrupter (GFCI) to know the causal factor. Contact a technician if you cannot detect the actual problem.

7. Address Grounding

Air conditioners are large appliances consuming much more power than other domestic electrical goods. The entire electrical setup in your home and all appliances require appropriating grounding. However, air conditioners and such large machines are more vulnerable to any faults in the grounding apparatus.

You must consult a technician to inspect any grounding issue or a short caused by a grounded compressor. The latter happens when any part of the winding wire or coil inside the compressor is damaged, broken, torn, or loose.

This detached electrical winding can hit the compressor sides or walls from the inside. Thus, the outdoor air conditioner unit will develop a short.

The broken winding can come in contact with and ignite the compressor oil. The air conditioner will suffer burnout, and a sudden surge in electricity will trip the breaker ( source ).

Grounded compressors are a severe problem.

Contact a technician immediately. Address every grounding issue with the same urgency, whether related to ground-fault circuit-interrupter breaker, outlet receptacle, or anything else.

Source: Occupational Safety and Health Administration

8. Repair Specific AC Problems

A comprehensive cleaning and thorough preventive maintenance should identify prevalent and potential problems in your air conditioner. Attend any and every significant issue to avert tripping the breaker.

Here are some standard solutions you have to consider per the problem:

Tighten loose electrical connections.
Fix wiring issues, both within and beyond the air conditioner.
Lubricate moving parts and service the blower or fan, the motors, and the blades.
Clean the coils and ensure they are in flawless condition.
Repair or replace malfunctioning safety devices.
Replace failing capacitors. Consider an additional capacitor for the hard start problem.
Refill the refrigerant or coolant to the recommended level. Fix any leakage.
Repair prevalent issues in the evaporator, condenser, and compressor.
Replace evaporator, condenser, or compressor, if necessary.
Repair or replace the thermostat if it is dying or dead.

Always contemplate preventive repairs whenever you consider fixing any of these problems. Allowing a glitch to linger often leads to a severe problem, more expensive to repair or replace.

9. Remedy Issues in the AHU

The outdoor air conditioner is more complex, thus vulnerable to many problems, than the indoor air handling unit, which is the circulating system. However, the indoor air handling unit also has a few major components, and a significant failure can trip the breaker.

Subject to the type and specifications, an AHU may have a mixing chamber, air filter rack, damper, sound attenuator, and the essential supply & exhaust ventilators or outlets. Elaborate ductwork, especially in a large property, requires a powerful air handling unit.

Like air conditioners, the air handling unit may cause a power surge. Clogged and dirty ducts, failing chambers or filters, malfunctioning ventilators, and both mechanical and electrical components in the AHU can trip the breaker.

Inspect the AHU and all associated components. Detect the problem causing the breaker to trip and choose a solution accordingly. Contact a technician if you are unable to identify the precise issue with your AHU.

10. Upgrade Old Wirings and Circuits

Outdated wirings and aging circuits are common in older properties. Assess if you need to upgrade the electrical setup, especially for large appliances like air conditioners.

Contemporary air conditioners are more efficient than older models, so are modern circuit breakers. Using a compatible breaker per the required amperage ensures a safe trip unit.

However, it may not be sufficient if you have old, poor, or worn-out wires in the circuit.

Older wires are more vulnerable to shorts and grounding issues, particularly for large appliances. Modern wires offer much less resistance, and their insulation quality is also improved.

11. Replace an Old AC

The last option is, of course, to buy a new air conditioner. Several significant problems in old air conditioners can cost a small fortune.

An AC unit tripping a breaker frequently is more than an annoying issue. Replacing the compressor or too many components and retrofitting are expensive propositions. Besides, a very old air conditioner is a fire hazard.

Short circuits in old air conditioners can trip the breaker and may cause a fire. A grounding fault can be hazardous.

Prioritize solving such grave issues while also considering if a substantially old and deteriorating air conditioner is safe for use.

Final Thoughts

Numerous variables are at play when an air conditioner trips the breaker and does so again after your reset. You may or may not know nor detect the causal problem. Always consider contacting an expert before you try anything without being entirely familiar or sure.

Why does AC Circuit Breaker Keeps Tripping and How to Fix It

why-does-ac-cirtuit-breaker-keeps-tripping-alphamechanicals-blog-post

Is your ac unit constantly tripping the circuit breaker ? Do you find it in constant need of repair? In this article, we break down the cause and effect behind problems with an AC unit’s circuit breaker, and solutions you can use to fix the problem.

What can cause an AC tripping circuit breaker?

Are you wondering “Why is my air conditioner tripping the breaker?” A circuit breaker can fail or trip for a variety of reasons. A few of the main culprits could be:

The breaker could be unreliable

While rare, a once-sturdy and reliable switch can weaken over time and trip, or even stop working entirely. This is easily solved by buying a new one and replacing the switch , either yourself or at the hands of a professional technician.

The compressor and/or fan can draw too many amps

This problem can have a variety of causes:

For example, if a motor gets stuck and doesn’t react properly to applied voltage, it will pull more amps. This can cause heat to generate in the wiring and cause the ac unit tripping breaker. While not tripping it automatically, it can trip when the thermostat signals the AC to turn on.

This pattern often happens with the compressor when the cool season starts . The compressor pumps refrigerant through the lines, and when this component fails or works irregularly, it can cause problems with the circuit breaker as well.

If the capacitor is in working order, adding a hard-start capacitor to the circuit can give it the boost it needs to spin the motor and get things going. Beware, however; this is an indication of a failing unit. Consider budgeting for a new compressor or ac unit, as it may fail at an unexpected time.

Short circuiting

A breaker can also trip because of an electrical short . This is caused when hot wire touches a path it’s not supposed to, such as a neutral wire. When the system is on and the power is active, the system can overload and the breaker can trip. The breaker will instantly trip when voltage is applied.

Touching wires

The breaker will also trip if a wire from the motor touches the inner walls of the compresso r. The windings within the motor help spin the motor sheath, and these windings should be covered to shield the wiring. However, this is still a cause, primarily on older systems that have been active for 10-20 years or longer. The electricity grounds into the floor, and the ac unit keeps tripping breaker.

Incorrect refrigerant pressure

Refrigerant pressure at the wrong level can trip the AC breaker and cause other trouble. High levels of refrigerant pressure causes the compressor to strain to work properly, causing a breaker trip eventually. This problem is rarer than other ones, but can look like a bad compressor.

How to solve problems when AC keeps tripping breaker

When the breaker is unreliable.

This problem is easily solved by buying a new breaker and replacing the switch, either yourself or at the hands of a professional.

Look for identifying signs of short circuiting: visible burns on wiring, burning smells, or flickering lights. Confirm potential shorts with a multimeter.

When wiring is out of place

If a breaker is tripping because exposed wires are touching the inner walls of the compressor, covering the exposed wires will shield the current.

When refrigerant pressure is incorrect

Removing a pound of refrigerant should indicate a pressure issue, and your gauges should vary a bit. If this happens AND the temperature splits hovers between 18-22 degrees, you can remove refrigerant until the compressor amps drop below the RLA, and the temp split remains within range. If removing the refrigerant isn’t working, you might want to replace all the old refrigerant with virgin refrigerant and a factory charge. If you’ve done this and checked all other components on the system, and the compressor still pulls high amps, you have a bad compressor.

These are just some of the reasons your home’s circuit breaker would trip the breaker in the main electrical panel. If it trips immediately when turning it back on, it is likely a wiring problem. If it trips after a certain time period, there is an issue with a component in the AC system.

Let a professional do the fixing. We don’t advise that anyone take on these problems by themselves, and as a matter of fact, you might not even be able to purchase the parts you need for a DIY fix. Contact a profession to diagnose and fix the problem for the best possible outcome.

Looking for a quality AC repair in Sacramento Area?

How can maintenance prevent my AC tripping breaker?

Active maintenance on your AC unit will prevent wear and tear on the unit, and extend both its lifespan and quality. Think of an AC unit as a car engine; changing the oil or filling the tires can help prevent much larger issues later on. In the same way, monitoring your HVAC system can help prevent large-scale over time. To solve the question of “Why does my air conditioner breaker keep tripping,” we outline below how you can actively clean and maintain your AC unit.

To begin, read the manufacturer manual

If you don’t have a paper manual, you may be able to find it online. Make notes of maintenance periods and dates for your ac unit and all other components of your HVAC system; chillers, boilers, motors, etc. These manuals provide a standard for your HVAC upkeep, and work to keep your house in proper order.

To clean off the external unit: (Condenser and Compressor)

Power off the main unit.

When cleaning the ac unit, you want to ensure no power is traveling through it. You can either remove the breaker/block or move the switch to the off position. If this isn’t possible, you can also switch off power to the AC condenser at your main electrical panel.

Clear debris in and around the unit

Most debris will get stuck in the condenser fins, and this area needs to carefully be cleaned away. You can use a rough paint brush to deal with easy-to-remove debris, and follow up with your vacuum and brush attachment. Remove debris and plant growth that is within 2 feet of the unit.

Clean and straighten the AC fins

Fins can collect debris that is not easily removed with a brush. Instead, an old knife can scrape out debris that is stuck between the fins, and reshape any damaged or bent fins.

Clean the condenser fan

This is another area where debris needs to be cleaned regularly. This component can be wiped with a damp cloth and left to dry in the sun.

Cleaning the fins inside out

The best way to clean the fins is by spraying them with a garden host. This removes caked-on dirt that other methods wouldn’t dislodge. Take care to not get water on the fan motor, and if the motor doesn’t have sealed bearings, check the fan lubrication as well. A few drops of electric motor oil should work nicely.

To clean the internal unit: (Evaporator and Blower)

Clean the evaporator coil.

The evaporator coil door can be found inside the blower/furnace unit and accumulates lots of debris. Use a soft brush to remove dust, then spray with a no-rinse coil cleaner to remove other gunk and improve efficiency.

Clean the evaporator drain

The evaporator drain can get clogged due to algae and mold buildup, and needs to be unplugged. A clogged drain can cause flooding and stop the unit from functioning until the water is drained. Clogs can also cause odor to build up and leak from the unit. A wet/dry vacuum cleaner can remove debris from the evaporator drain.

Change the blower filter

This step changes depending on where you live. In dusty environments (such as here in Sacramento), filter changes are necessary more often, typically right before the starting of the “heating” and “cooling” seasons. The filter is typically found at the end of the fresh air return duct.

Completing all these steps should ensure your HVAC and AC unit stay clean and regulate temperature more effectively. When all parts are dry and in place, you can turn on the power and test that the unit works correctly. This maintenance will prevent issues where the air conditioner trips circuit breaker.

Why Does My Air Conditioner Breaker Keep Tripping? Here’s Your Fix!

By Author Michael Joseph

Posted on Last updated: July 24, 2022

Your AC breaker is a safety feature that automatically turns off the system whenever a power overload is detected. If your air conditioner breaker keeps tripping, it’s because the system is taking in more amps than it’s rated for, which could happen for several reasons.

This happens to prevent damage to your equipment from overloaded circuits. So make sure that you don’t ignore the issue if it’s one that you’re having.

Most importantly, don’t continue to reset your AC breaker . Your main goal should be figuring out what the problem is so that you can solve it or hire a technician. We put together this article to help you do that, so keep reading to learn more.

Start with these steps

It bears repeating: You don’t want to just continue flipping back the breaker switch if it keeps tripping. Instead, follow these steps to start isolating the issue so that you can solve it safely:

Turn off your air conditioner at the thermostat.
Flip the AC circuit breaker switch into the “ON” position.
Wait for about 15 minutes with the air conditioner off.
Turn the air conditioner to the “COOL” setting.

Here’s what might happen next

After you complete the four steps shown above, there are three different things that might happen. We’ll cover each of those below.

1. It operates normally without tripping the breaker

If this happens, great! It’s a sign that your air conditioner is back to working normally. It means that your issue was likely tied to a momentary power surge or some other chance occurrence that won’t happen again.

These types of issues are generally not something you need to look further into unless they happen consistently. It’s often caused by a problem that’s external to your household.

2. It works for a while and then trips the breaker again

This could also happen, which can be frustrating. But the good news is that you may be able to solve the problem yourself. You can try replacing your AC air filter to see if that works.

Your air conditioner relies on a clean air filter to get the airflow that it needs to function properly. When the filter is dirty, the system has to work harder, and that can lead to overheating that trips the breaker.

Replacing your filter is super straightforward. You can refer to your owner’s manual to get step-by-step instructions that are specific to your system.

3. The breaker trips immediately

It’s also possible that the breaker will trip right away after you turn your AC back on. Unfortunately, this isn’t something that you’re likely going to be able to fix on your own. Instead, it’s time to call out an AC repair company to come and take a look at your unit.

You can also keep reading to learn more about the mechanical reasons why this keeps happening.

Here’s why your air conditioner breaker keeps tripping (from best-case to worst-case scenario)

The circuit breaker is faulty.

This is the best-case scenario because it means that you need to fix the breaker, not your AC unit. It means that your issue will probably be less expensive to solve.

There are a few reasons why this could happen. One is that you may have a circuit breaker box that doesn’t give your home enough power. For example, a 4.5-ton air conditioner typically needs a 35A breaker to work correctly.

It may also be as simple as a loose wire. These can happen due to natural contractions and expansions that occur when the temperature changes over time.

Here are some of the top signs that you’ve got a bad breaker:

There’s a burning smell near the breaker box. This can happen when wires and their insulation get overheated.
Your breakers are hot to the touch. This is self-explanatory. The same heat that leads to your wires burning can also cause the breakers themselves to get warm.
You can see visible damage on the circuit breaker.

The solution to a bad breaker is to replace it with a new one . You can confirm that this is necessary by seeing if a breaker is loose when you manipulate it.

The good news is that these are pretty inexpensive and not the most challenging thing to replace. But if you’re not comfortable with electrical work, then an electrician should be able to handle it for you at a reasonable price.

You have dirty condenser coils

It’s also possible that your air conditioner circuit breaker keeps tripping because you’ve got dirty condenser coils. This part’s job is to release heat from the inside of your home outside. It’s typically on your outer unit, which means it’s constantly exposed to the outside elements (wind, snow, etc.).

Condenser coils may get covered with various types of grime and debris periodically. When this happens, they aren’t able to release the heat that they need to. This causes your AC to work harder and can lead to overheating that trips the safety breaker.

You should be able to see this visibly, as most modern units discharge warm air out of the top.

Fixing this problem may be as simple as cleaning the condenser coils . You can open up your outdoor system and look for any dirt. When you see some, spray it with a cleaner and wipe it with a rag.

Luckily, you don’t need a complicated cleaning solution for this task. You can just mix together some warm water with your favorite cleaning product, and that should be enough.

Your fan motor is malfunctioning

The overheating problem that you’re experiencing may also be tied to your air conditioner’s fan motor.

This problem is similar to what can happen with your condenser coils. The same outside elements could reduce the efficiency of your fan, which causes the AC unit to have to work harder.

That creates a situation in which your air conditioner is drawing more electricity than it would normally need to compensate for the lack of efficiency. If this happens consistently, the capacitor can overload. And your air conditioner will trip your breaker as a result.

You can check for this issue by looking to see if your outdoor fan is spinning . If it is, then your problem may lie elsewhere. But if it’s not, you might have a broken fan motor that needs to be replaced. It will cost about $250 to $700 to replace on average.

That being said, make sure to look into the various reasons why a fan may not be spinning . Because it can be indicative of several different problems.

Your evaporator coils have frozen

It’s also possible that your evaporator coils have frozen, and that’s causing your AC circuit breaker to trip continuously. This can happen when too many debris accumulates in your system and airflow is reduced.

This is a pretty straightforward issue to spot. Simply take a look at your evaporator coils and see if there’s any ice on them. You may also want to check for puddles of water nearby in case they’ve recently thawed.

The solution is to give your evaporator coils 24 hours to thaw out . While that’s going on, you can clean the coils to make sure this doesn’t happen again.

You may also want to give your entire air conditioner a thorough cleaning and swap out the air filter. The cleaner your system is, the more airflow that it gets. And that will decrease your chances of experiencing frozen coils again the next time you use your air conditioner.

You’ve got low refrigerant levels

Air conditioners use refrigerant to cool down the air that they process. This liquid is designed to be a closed loop that doesn’t need topping up under normal circumstances.

However, sometimes you can get punctures in your refrigerant lines, which lead to lower refrigerant levels over time. This will cause your system to pull in too much power and may lead to tripped breakers.

The only solution to this problem is to call an HVAC professional . Refrigerant is a toxic liquid that isn’t safe to deal with unless you know the proper way to do so. To avoid putting yourself or your family at risk, it’s best to let a professional take over from here.

The compressor isn’t starting

Finally, the problems you’ve been experiencing could also stem from the compressor itself. It may have trouble starting, which could cause it to draw in too much power and trip the breaker immediately.

Normal AC units should turn on within about a second of the time that you flip the switch. If your air conditioner takes longer than that to get going, it’s a big sign that you’ve got a compressor issue.

The unfortunate news is that compressor repairs and replacement cost about $1,250 on average . That means it may make more sense to just replace your system with a new one at this point—especially if you’ve had the current AC for a long time already.

Either way, your next step is to call an HVAC professional so they can diagnose the problem and advise you on your options.

AC Float Switch – What It Does and Why You Need One

An AC float switch is a crucial component in your air conditioning system that helps protect your home from water damage and ensures the efficient operation of your HVAC unit. Here’s a summary of what an AC float switch does and why you need one:

1. Function of an AC Float Switch: An AC float switch is a safety device installed in the drip pan beneath the indoor unit of your air conditioner. Its primary function is to monitor the water level in the drip pan.

2. Detects Water Accumulation: The float switch contains a buoyant switch mechanism that rises with the water level in the drip pan. When an excessive amount of water accumulates, typically due to a clogged drain line or other drainage issues, the float switch is triggered.

3. Activates Shutdown: When the float switch is triggered, it sends a signal to your HVAC system, causing it to shut down. This immediate shutdown prevents the AC unit from continuing to produce condensate and potentially causing water damage to your home.

4. Prevents Water Leakage: The presence of an AC float switch helps prevent water leakage from the air conditioner, which can damage ceilings, walls, and flooring, and lead to costly repairs.

5. Alerts for Maintenance: When the float switch is activated, it serves as an indicator that there is a problem with your AC system, such as a clogged drain line. This prompts homeowners to address the issue promptly, preventing further damage and ensuring the system’s efficiency.

6. Why You Need One: AC float switches are essential for several reasons:

Protection from Water Damage: An AC float switch acts as a safeguard against water damage to your home, which can be costly and disruptive.
System Efficiency: By alerting you to drainage issues, the float switch ensures that your AC system operates efficiently, reducing energy consumption and extending its lifespan.
Peace of Mind: Knowing that your AC system has a safety mechanism in place to prevent water damage provides peace of mind, especially during humid weather or when you’re away from home.

Relationship between AC Evaporator Coil, Drip Pan, Drain Line and Float Switch

An air conditioner system is made up of 4 main components:

Evaporator coil
Condenser coil
Expansion valve

All the 4 components are connected together using copper tubes and a refrigerant/coolant (commonly known as Freon) circulated between them. The evaporator coil is the one located inside the house and that is where cooling actually happens.

Condenser coil and compressor are located outside the house. The refrigerant absorbs heat from the indoor air and releases it to the outside inside the condenser coil.

What most people forget is that an air conditioner’s job is to not only to cool the indoor air. It also dehumidifies it.

The refrigerant enters the evaporator coil as a cold liquid. A fan pulls warm and humid air from the house and forces it across the coil.

When the warm air comes into contact with the cold coil, the refrigerant absorbs heat from the air and that is how cooling happens. Cooled air is then sent back to the house through the supply air ducts.

When the water vapor in the air (humidity) is subject to the cold coil temperatures, it condenses (becomes a liquid). That liquid has to go somewhere otherwise it will drip on the floor/ceiling and cause extensive water damage.

For that reason, there is a pan placed under the evaporator coil known as a condensate drain line or AC drip pan. The drip pan collects the condensate from the coil but it should not stay in it for long.

A condensate drain line is connected to the drain pan to continually drain the condensate to the outside. When everything is perfect, this system works very well.

Where is My AC Float Switch Located?

The location of your AC float switch will depend on what kind of AC unit you have. There 2 types of HVAC units:

Vertical units
Horizontal units

In vertical units, the evaporator coil is located on top of the furnace or air handler. Warm air enters the unit at the bottom and cold air leaves from the top.

In horizontal HVAC units, air moves sideways. Warm air enters from one side while cold air leaves from the other end. These installations are found in attics or crawlspaces where there isn’t enough space for vertical installations.

Thanks to gravity, the condensate in vertical units can only flow downwards. As such, vertical units have only one condensate drain located below the evaporator coil.

Things are however a little different for horizontal units. The condensate has the potential to flow sideways, outside the area covered by the drip pan.

For that reason, horizontal units have a primary drip pan (located under the evaporator coil) and a secondary drip pan located underneath the entire unit. The secondary drip pan acts like a backup for the primary pan.

If you have a vertical unit, the float switch will be located somewhere on the condensate drain line. On the other hand, if you have a horizontal unit, the AC float switch will be located on the secondary drain pan.

How an AC Float Switch Works

An AC float switch comprises of a very simple mechanism. There is a small piece of plastic (the float) at the end of the switch which can slide up and down easily.

This float is also connected to 2 wires. The 2 wires are connected to the AC electronic system and specifically the thermostat.

When the float is at the bottom of the assembly, the 2 wires have a good contact, meaning that current is flowing through the system and hence the AC works normally.

The reason why the float stays at the bottom of the assembly is because there is nothing to move it up. As such, the contact between the 2 wires remain intact.

However, when the AC drain line is clogged, the condensate cannot be drained hence water level in the pan starts to rise. As the water rises, the float keeps sliding upwards relative to water level in the pan.

When the water level in the drip pan reaches the critical or set point, the float breaks contact between the 2 wires’ terminals. When that happens, the electric circuit path will have been broken and the AC will turn off.

As you can imagine, when the AC is turned off, warm and humid air will not be pulled from the house meaning that no more condensate will be produced. The drip pan will therefore not overflow, protecting your house from water damage.

How Do You Reset an AC Float Switch?

If your AC float switch has tripped, you will only need to drain the water in the condensate drain pan to reset it. That will however not fix the problem because as soon as the pan is full again, the switch will trip.

In fact, if your AC float switch keeps on tripping, it is a sign that the drain line is clogged. To prevent it from tripping again and again, you will need to first unclog the drain line.

Note : Some secondary AC drip pans have a drain line while some don’t. If your secondary drain pan has a drain line, you will need to inspect it as well as the primary drain line.

To quickly drain a condensate drain pan full of water , use a shop vac to suck out the water. When that is done, you will also need to unclog the drain line.

To unclog the AC condensate drain line, connect the shop vac’s house to the drain line end outside the house and run it for about a minute. You can use a rag or tape to create a better seal between the vac’s hose and the drain line.

How to Prevent AC Float Switch from Tripping

To prevent your air conditioner float constant tripping, you have to ensure that the condensate drain line does not clog. Because of the humid nature of the evaporator coil, the condensate drain line is a perfect breeding ground for mold, mildew, algae and other such organisms.

Over time, these organism will multiply and completely clog the drain line. Failing to change the AC filter or using the wrong size of filter can also cause the drain line to clog.

Ideally, an AC filter should be change after 90 days but inspected monthly. You should also use the correct size to prevent dirt particles from passing and clogging the drain line.

Here however is how you prevent mold from growing and clogging your drain line:

Remove the AC drain line cap
Pour about ¼ cup of vinegar down the drain line
Wait for about 15 minutes then flush the line with boiling water.
Put the cap back on.

Apart from cleaning the drain line with vinegar, you can also regularly (after about 3 months) connect a shop vac to the AC drain line and pull out and gunk that can have the potential to cause a clog.

Float Switch vs Wet Switch

Unfortunately, float switches are not foolproof. Sometimes they do not work as designed. And that is why your HVAC technician may recommend something known as a wet switch.

As I mentioned, float switches uses a float to trigger a switch and turn off the AC. On the other hand, wet switches use water to complete a circuit between 2 metal probes.

In terms of effectiveness, wet switches are more effect that float switches. They will promptly turn off the AC when as much as a drop of water gets to them. On the other hand, there will need to be a high water level in the pan for the float switch to turn off the system.

Wet switches are more expensive than float switch but is really nothing compared to the cost of fixing water damage related problems.

And that is everything in as far as Air conditioner float switches are concerned. I hope that this post was helpful.

Why Does My Central Air Conditioner Keep Tripping the Breaker?

The last thing you want on a sweltering summer day is to have your air conditioner keep turning off because the circuit breaker keeps tripping. Your home’s circuit breaker is a safety measure that protects against damage from overloaded circuits, which could cause a fire. Your AC constantly tripping your circuit breaker means that it’s pulling in too many amps than the breaker was designed for.

This is a problem that you definitely need to address before it gets worse. Don’t just keep resetting the circuit breaker. You need to see an AC repair specialist immediately in order to prevent further damage and potentially dangerous situations.

The first thing you should do if you’ve noticed a problem with your AC circuit breaker is to make sure there really is a problem. If there was a recent storm or power outage, the circuit breaker might’ve been tripped in a one-time power surge.

However, if the problem has happened more than once, it’s likely an issue with your AC system. You might be able to simply reset your air conditioner’s internal circuit breaker. Take the following steps to do so:

Turn the AC system OFF (on the thermostats)
Reset the AC circuit breaker switch in your electrical panel to ON
Wait 30 minutes with the air conditioner OFF
Set your air conditioner back to COOL

If everything works as it should after this reset, you’re good to go! However, if the AC circuit breaker immediately trips again, or if it won’t turn on at all, you likely have a problem that needs to be looked at by a professional. If the AC system works for a little while before turning back off, there might be something you can do to fix it.

Call Your Trusted Toronto HVAC Professional

Your air conditioning system is a large investment, one you don’t want to risk by accidentally breaking something even further in an attempt to fix it yourself. While there are many maintenance tasks that are easily accomplished by homeowners, an electrical issue is something best left to an AC technician with the knowledge, skills, and qualifications to handle it.

If you’re unsure of what the cause might be, the best way to ensure peace of mind is to contact your local HVAC technician for AC repair . A certified technician will be able to walk you through any possibilities, help you troubleshoot, and determine if the issue is something minor that you can fix yourself, or if it will need to be professionally serviced.

8 Reasons Your Central Air Conditioner Keeps Tripping the Breaker

1. dirty condenser coils.

If you’ve been neglecting your yearly AC unit maintenance, you might’ve noticed that your home isn’t as cool as it should be. Dirty condenser coils might be the issue, and luckily it’s one with an easy fix.

When your condenser coils get dirty, they lose their ability to disperse heat. This can lead to the air conditioner overheating, which may be the cause of tripping the circuit breaker.

Dirty coils are usually caused by a buildup of dust and debris on the outdoor unit. Make sure you’re doing your yearly cleaning—and scheduling regular tune-ups—to keep the condenser coils in good condition.

2. Dirty Air Filter

Dirty filters may cause your air conditioner to trip the circuit breaker. Reduced airflow means the fan motor must work harder and longer to draw air through the filter. This can draw too much electricity, causing the air conditioning unit to overheat and resulting in an electrical short.

If you’ve noticed puddles of water around your outside AC unit or there’s no cool air coming from your AC , it might indicate restricted air circulation, which might be the cause for why your breaker keeps tripping. The easiest fix for this is to change the dirty air filter. Air filters should be cleaned and changed regularly , depending on how often you use your AC.

3. Old Air Conditioner

Nothing lasts forever, and your air conditioner is no exception. If your system is over 10 years old, it’s probably nearing the end of its useful life. The time will come when the cost of extensive repairs to keep an older unit running is more than it would cost to replace it with a new AC unit .

Older units will show signs of failure before they break for good. If the air conditioner’s circuit breaker tripping is only one of many issues you’re seeing, it’s time to consider replacing your unit.

4. Faulty Fan

Your AC system uses fans to help move air around, blowing over the coils to release the heat from your inside unit. If the motors that run these fans are damaged or dirty, your AC system will be using more energy, which might be the cause of your AC breaker trips.

If the fan blades are coated in dust and debris and slowing down the fan, a thorough cleaning might be enough to fix the problem. However, if the motor that runs the fan is malfunctioning, an AC technician will have to replace the motor.

5. Frozen Evaporator Coils

When maintenance is neglected, problems start to build up. Eventually, airflow is reduced, which causes the AC evaporator coils to freeze up . If you’ve had issues with your AC tripping the breaker, and if you see ice on the coils of your AC unit, it’s best to keep the system shut off and call in a professional. Keeping it running might result in compressor failure, which is a much worse problem to have.

6. Compressor Issues

Compressor failure is a serious issue that may require a whole new system. As the heart of the air conditioning system, your compressor pulls in lots of power when it starts up. As a compressor ages, it will have trouble starting, which pulls in even more power and can result in circuit breaker trips.

If you have a grounded compressor, that means electrical wiring inside the compressor has broken and is touching the side. This causes a direct short to ground, and usually, this will ignite the oil, causing a burnout. A faulty compressor means you’ll have to replace the AC unit altogether.

7. Refrigerant Leaks

If you have an older AC unit (especially one that hasn’t had regular maintenance), corrosion can develop on the coils. This can lead to cracks and holes in the refrigerant lines, which will cause a refrigerant leak. When the refrigerant pressure drops, air conditioners have to work harder to cool your space. As a result, the unit will draw too much power and cause breaker trips.

8. Loose Wiring

There are plenty of wires connected in both the outdoor and indoor unit of your air conditioner that keep things running. Any of these wires might become loose or lose their connection, and this can cause a short circuit, resulting in a tripping breaker.

Wiring issues are best left to an AC tech. They can re-wire any faulty circuits and replace a bad circuit breaker.

Portable AC Tripping Breaker? (10 Possible Causes & Fixes)

When the temperatures skyrocket in the summertime, the one appliance that works overtime is the AC . If your portable AC unit keeps tripping the breaker, you can do a few things before calling a service tech. The one thing you do not want to do is keep resetting the breaker if it continues to trip it.

The reason the breaker is designed to trip is to protect the appliances and all electrical equipment. It will also protect your home from burning down. So what are the causes, and what should you do if this keeps occurring?

Do You Need to Hire an Electrician?

Get free, zero-commitment quotes from pro contractors near you.

An air conditioner will trip mainly because there are more amps getting pulled y the breaker than what the breaker is rated for. So, if you have your portable AC pulling 30 amps on a 20 amp breaker, this will trip it. Don’t keep resetting it as you may cause a fire and harm your AC.

What Do You Do When the Breaker Trips?

These are the steps to follow if the breaker has only tripped one time.

Step 1: Turn off the Unit

Turn off the portable AC Unit from the power switch. Some only have the thermostat to turn it off.

Step 2: Reset the Breaker at the Breaker Box

Go to the breaker box and note the breaker will be in the middle of the ON and OFF switch. Flip the switch to the off position then to the on position.

Step 3: Wait 30 Minutes Then Turn AC On

You must wait for 30 minutes before turning the portable unit back on. This allows the internal circuit breaker of the unit to reset itself. When the 30 minutes is up, turn the AC back on to COOL.

Step 4: Wait and See

When the compressor is on, if the breaker does not trip, it was a power surge. If the breaker keeps tripping, then you will need to call an HVAC certified technician. If the breaker stays on for a time, then kicks off, then keep troubleshooting.

Power Surges Tripping the Breaker

When lightning strikes too close to the home, power lines, transformer, or anything electrical, power surges occur during a thunderstorm. It simply means too much electricity is overloading all of the circuits, and the power goes out. In some cases, it will trip the breaker one time, and it is okay to reset the breakers.

There is nothing anyone on earth can do to prevent power surges. It is something that happens from Mother Nature or even the power companies. If the breakers do not cut off in a power surge, the chances are high; the electrical components will burn.

If the Air Filter is Dirty, The Breaker Can Trip

When everyone talks about maintenance on any air condition, what is the one thing that is stressed? The air filter needs to be cleaned or changed regularly. This calls for once a month to keep the air flowing properly.

If the air is not flowing correctly, then the portable unit works overtime, drawing more amps. When this happens, the breaker will cut off, sparing the unit and the outlet. Once the filter is cleaned or changed, and the breaker stays on, you have solved the number one problem.

The Condenser Coils Are in Need of Cleaning

If the condenser coils are dirty, they can make the AC work overtime to keep the home cool. You can clean them with a vacuum cleaner hose with the brush attachment. There is a kitchen degreaser you can also use to take off the grime if there is some.

You can use spray bottles for the degreaser and use another for regular water to rinse off the coils. Once the coils are clean, try turning the breaker on again. If it kicks off after a while, continue troubleshooting.

For the rest of the steps, there is nothing more you can do. It will take a professional from here on out. Everything else deals with the electrical box or the components of the AC itself.

You will need to separate the two in the troubleshooting steps because it will take two services. One will be an electrician, and the other will be an HVAC service tech. You may get lucky and find one that can do both the box and the AC unit repair.

There May Be a Loose Wire Going to the Breaker

If there is a loose wire, faulty capacitor, or a short circuit in the wires, DO NOT ATTEMPT TO FIX THESE!!! Call a professional when it comes to the electric breaker box. If any of those things are the problem, it will trip the breaker every time.

An Overloaded Circuit Will Shut Off the Breaker

In these situations, the AC is not the problem. The breaker itself may not have enough amperage to cover the AC unit. If the AC is pulling 30 amps off a 20 amp fuse and breaker, it will trip the breaker.

The same applies to all appliances like refrigerators , microwaves, dishwashers, and other large appliances. When these appliances are running at total capacity, a lot can happen. Only an electrician can determine the cause and repair it.

Having a Faulty Fan Motor Can Trip the Breaker

We have covered everything an electrician can do for the breaker box. Now we move on to the HVAC services when the fan motor goes bad. There could be multiple reasons the fan motor goes bad, but usually, the only option is to replace it.

It is something that can strain the unit while pulling too many amps. These types of breakdowns all overload the circuit.

A Few Reasons The Evaporator Coils Are Frozen

These reasons below will freeze up the coils and strain the unit into pulling too much energy. The service tech will evaluate the situation and fix the problem. Afterward, if any of these are the problem, it should solve the breaker issue.

If the air filter is dirty, the coils will freeze up. (As mentioned earlier this you can fix yourself.)
The temperature outside may be too cool to run the AC. This will also cause ice on the coils.
If the system is low on refrigerant, the coils will freeze due to the strain. The breaker may trip if the unit is overworking.

If The Refrigerant is Low Much Can Occur

Refrigerant is like the blood that flows through the system to maintain the proper temperatures. If there is a leak, not only will the coils freeze up, but the portable AC will not blow cool. The number one cause for refrigerant leaks is due to corrosion on the coils from lack of maintenance.

It is also possible the system may be old and did its time. However, cracks and holes develop over time with these issues. If it is one or two leaks, it can be fixed.

The lines and coils will need to be replaced if there is more. Communication will occur if a complete replacement needs to happen. Since this also strains the unit, more energy than usual will cause the breaker to trip.

If the Compressor is Going Out There is Problems

The heart of the unit is the compressor. If this fails, not only will there be breaker problems, you may have to buy a new portable AC. The compressor is the component inside the AC that draws the most amps.

If the compressor strains to come on or go on and off, much power is drawn from the circuit. This would be a huge sign that is the cause of the breaker tripping. If you notice, most of these problems can be avoided by proper maintenance.

A Grounded Compressor Will Shut Down the Breaker

A grounded compressor means the electrical winding within the compressor is broken and has touched the compressor’s side. When this happens, it shorts out the circuit within the component, and it will automatically trip the breaker. Of all the problems, this is the worst.

For sure you will need a new compressor. If there is no more warranty, it is cheaper to buy a new unit.

What is the cost of energy burned on a portable AC unit?

The prices range from $.07 per hour to $.20 per hour. It also depends on how low the thermostat stays.

What are the safest temperatures to keep the inside of the home?

If you are looking to save money, summertime should be 78 degrees. When you are running the heat in the winter, 68 degrees is the best.

AC Float Switch Keeps Tripping: Reasons and Solutions

Written By David Clark
Updated December 13, 2023

Think about a hot summer day with an AC that is not running properly. Nothing can be the worst scenario than this on a hot summer day. One of the most common reasons for AC not working properly is the inactivity of the float switch. Also the tripping of the float switch.

So, here we are with our article to help you.

A common question is- Ac float switch keeps tripping, what to do?

One of the reasons for tripping the float switch is the clogged drain line of the AC. The drain line can be clogged by molds and algae. We can manually remove those molds. Using vinegar, or bleach can clean the drain line. Also, with a shop vac, and drain snake we can clear out and unclog the drain line.

So, let’s know the reasons for tripping the floating switch of your AC. Then you will get to know the fixing processes also.

What's On The Page

How Do I Know If My AC Float Switch Is Bad? – Diagnosing The Switch

But hey, before you go in for all badass mode blaming the float switch, wait a little bit. How do you know the float switch is indeed causing all the problems? Well, the best way to know that is to test or diagnose the float switch.

Unit Keeps Shutting On And Off

One of the most common signs that your AC float switch is tripped is the malfunction of the unit. The unit will work and cool the house as you turn it on. But after 5 or 10 minutes of operating, it will suddenly shut off. And then, it will turn on automatically after a while.

Warm Air Blowing

The float switch is part of the outdoor unit and has a 24V connection. Since this connection controls pretty much everything, if the switch gets tripped, the unit’s various parts will begin to shut down. And the room will begin to get warm. The thermostat still might stay on as it runs on batteries.

Though it is not commonly used, if you are using a float switch that comes with an LED indicator, things will get simpler. If the float switch gets tripped, the LED indicator will turn on. So you can check on that light to know whether or not the switch is at fault.

Testing With Multimeter

If you still can’t determine the cause, it is best to just test the switch using a multimeter. If you have a multimeter, proceed to do the following.

Turn off the AC unit.
Locate the float switch using the user manual.
Remove the float switch.
Turn on the multimeter and set its settings to Ohms.
Take the two probes of the multimeter and connect them to either of the wires of the switch.
If you hear a sound, that’s continuity.
Now raise your float switch as it’s still connected to the multimeter and check again.
If there is no reading or no continuity, the float switch is indeed tripped.

AC Float Switch Keeps Tripping: Possible Reasons

Solutions without knowing the reasons are like a ship without a rudder.

Before fixing the problem of the AC float switch, you need to find out the reasons. Otherwise, you will have to face more problems with the float switch of an ac.

Ac float switch keeps tripping , what can be the reasons? Let’s find out.

AC Float Switch Clogged

If the drain line of AC is clogged, then the water won’t pass out. And it is one of the main reasons for tripping the float switch. If this happens, then your AC will not turn on. So, if your ac is not turning on, check the drainage system.

AC Drain Pan Full

AC collects heat from the air. Also absorbs moisture. Condensing together they store water in the drain pan. So, check if the water pan or AC drain pan is full. If yes then it is causing the tripping of the float switch.

Water Near AC Unit

Excessive water near the AC can cause tripping of the float switch. As you already know, AC absorbs the moisturizer. So, don’t keep a bucket of water near the AC.

How To Clean AC Float Switch: 5 Ways Explained

As you know the reasons now let’s move on to the solutions.

Try to make sure your drain pan is not overflowing. Try to keep it in a good situation always. Check the drain pan while changing the dirty air filters.

If the drain line is clogged, you need to unclog it. If water is unable to pass out, molds grow in the pipe. It can be the reason for clogging the drain line.

Note : Before following any steps, do not forget to turn off your AC.

So here are the ways of cleaning out the clogged drain line.

Find the blockage. If the blockage is at the end or in the starting of the drain line, fix it manually.

If the debris is in the end, then clean it just with your finger.

Also, you can clean the debris with a hard brush.

By Water and Shop-Vac

With the flow of water and your shop vac, you can clean the drain line.

Connect the hose of the shop vac with the end of the drain line PVC pipe.
If the hose is not fitting with the pipe then knot it with a rope or tape it to fit.
Turn on the Shop-vac.
Pour enough water from the starting point of the drain line of your AC.
The shop vac will suck the water along with any debris or algae or mold.

So this is how you can clean the drain line with your shop vac to increase your AC Efficiency.

By Drain Snake

If the blockage is too hard to clean with a shop vac then a drain snake will help.

Take the drain snake. Put it from the starting point of the drain line.
Push harder the drain snake.
Pull the drain snake back.
Drain snakes will be tangled with debris or other waste.

So, using a drain snake, the drain line will be clean. And the float switch will not be tripping anymore.

Using Vinegar

Before using vinegar, you need to be careful about the material of the drain line pipe. Using vinegar in any metal can cause corrosion. Corrosion can destroy the whole system of your AC. So make sure you are using vinegar in a PVC pipeline.

Let’s know the DIY process step by step of mold prevention.

Find the clogged portion of the drain line.
If there is any algae or blockage at the end of the drain line then remove them.
Use a brush or any hard stuff to remove the blockage.
Now, open the t-shaped vent by removing the cap of it. Distill the vinegar. And pour it into the drain line pipe. Don’t use more than 1 cup of distilled vinegar.
Now, wait for 5-10 minutes to dissolve the mold which is inside or in the middle of the pipe.

Try to do this once every month. It will keep the drain line clean. And you will get better performance from your Ac.

Using Bleach

Using bleach and vinegar both go through the same process. The difference is that you can use bleach as an alternative.

Either use vinegar or bleach. Never mix them together. Mixing vinegar or bleach produces chlorine gas. Which is dangerous.

So, if you do not have vinegar but bleach, distill it. And flush the drain line with the distilled bleach.

If any of these don’t work, then you need to rebuild the drain line. Also, you can call an HVAC professional.

Things to Keep In Mind

You know the reasons which are making the float switch tripping. So, you need to be careful about those reasons. Need to make sure the drain line of the AC is clear.

If not, then you know the hacks now.

By shop vacs or drain snakes or manually you can easily clean the drain line. Just be careful when you are using vinegar or bleach.

AC Float Switch Failure- Reason & Solution

The float switch getting tripped is certainly a problem. Most of the time, moisture or water in the drain pan and a clogged switch can be the main culprit. However, if the switch fails, it often has other issues involved. So let’s find out some more reasons and what to do about them.

Incorrect Configuration

Every AC unit requires a specific type of float switch. It has some configuration settings that work only for certain types of air conditioning systems. But when the float switch on the unit does not have the right configuration or setting, it will go through various issues and fail at one point.

To understand the float switch’s configuration, you need to read the description and product manual first. Also, you have to install it in the correct way to avoid such inconvenience and maintain the switch by checking on it from time to time.

Quality Issue

The float switch quality matters more than one may think. The switch that your unit already has or the replacement you are using should be of good quality. If not, it can get damaged faster and eventually the switch will fail.

That’s why it is necessary to ensure the float switch is made with high-grade material or components. It is best to consult a professional to understand which one would be the right choice and also read the label description.

Not Rated For What It Does

Every AC float switch comes with a specific rating that indicates how much of an electric load it can handle. If the switch isn’t rated for your AC unit, the pressure will be too much for it and the switch will fail. In fact, it can end up causing severe damage.

Your AC manual should contain information regarding the rating of a compatible float switch. If not, you can consult with a professional HVAC technician for help.

End Of Lifespan

How long has the unit been operating? Or, if you replaced the float switch already, how long has it been since the replacement? The float switch, like all other parts and components, will expire at some point. So if the switch has reached the end of its lifespan, it could be the reason why it failed.

The only solution for you here is to replace the float switch. And here is what you need to do.

Turn off the AC unit power.
Take off the front cover.
Disconnect the old float switch’s wires.
Remove the old one and place the new float switch in its place by pressing it down.
Connect the wires to the terminals.
Place back the unit cover and secure it in its place.
Turn on the AC unit.

Is A Float Switch Supposed To Hold Some Water?

The float switch’s job is to monitor the condensate drain pan’s water level. As soon as the water level rises to a certain level, it triggers the float switch and stops the water from filling the pan any further. Thus, it prevents water from overflowing the pan or causing any water damage.

But is the float switch supposed to hold water? Well, that depends on what you mean by holding water.

Does the switch hold water in the pan and prevent it from overflowing? Yes. But does it hold water inside its system? Of course not. Since the float switch is more like a buoyant, it has no chamber to hold water.

Why Does My AC Safety Switch Keep Filling With Water?

Your AC’s safety switch isn’t supposed to keep filling with water. It is a safety mechanism that is part of the air conditioning system. So if it keeps happening, it can indicate a severe issue. This can block the water flow system and prevent water from entering your house. But why does it happen?

The most common reason behind it is that the safety switch is probably installed too low on its pipe. Another reason why it could be filling with water is because the pipe has a backflow issue.

The easiest way to prevent or fix this problem is to check on the safety switch and the areas around it. If there is dirt, debris, or any blockage, you need to clean it up so that water can move freely without any obstruction.

Check for any leak around the gasket and see if the seal is broken. If there is a leak, the switch needs to be replaced. But if replacing the switch does not resolve the issue, you need to get it checked by a professional.

Air Conditioner Float Switch Reset

Despite taking all the measures to troubleshoot the tripping float switch, you might still face the issue. That could be because there are other internal problems with the switch or its components. So, before you take the air conditioner to a professional to resolve it, here is one more thing you should try. And that is resetting the float switch.

Though resetting the float switch is a fairly straightforward method, it does require a few simple steps. I must mention that it is pretty similar to the Aquaguard float switch reset process shown in this video . So here is the step-by-step tutorial on how you can reset your air conditioner’s float switch.

Step 1: Turn off the Unit Power

First thing first! Before you attempt to reset the float switch, make sure to turn off the unit’s power. Turning it off ensures there is no chance of unexpected electric shocks or any other electric hazards to happen.

Step 2: Locate The Float Switch

Next, you need to locate the float switch. Now, this part could be a little tricky because the float switch can have different locations.

Generally, an air conditioner float switch is located in the condensate drain line and condensate drip tray. But where exactly is the switch located? Well, depending on the installation process, one can add more than one floating switch. And they can be found in-

Primary drain line
Secondary drain port
Condensate drip pan
Secondary drip pan

So check any of these locations to find the float switch. Another way to spot the switch is to look for a small rectangular or circular device connected to it.

Step 3: Remove The Cover

But the switch will have a cover on it. You need to remove that cover to access the switch. It should also be connected to the device connected to the float switch. So removing it would make everything easier. But you will have to use a screwdriver to remove it.

Step 4: Check For Obstruction

Keep your expectations low when it comes to finding a clean shiny float switch. Over time, the float switch gathers dirt and debris. And this issue often ends up obstructing the switch from going to ON or OFF mode. You can clean it up with a brush or fabric.

Step 5: Reset The Float Switch

Now it’s time to reset the float switch, which is a piece of cake. Just press and hold the switch for 5 seconds and the switch will be reset. You will know that as soon as you hear a click.

Step 6: Put The Cover Back On

Once the float switch has been reset, you need to put the cover back on. Then turn on the unit to power it up.

Step 7: Consult A Professional For Regular Maintenance

If resetting the switch does not resolve the issue, you will need to consult an HVAC professional. However, my suggestion is to contact a professional even if the resetting works to prevent any further issues.

10 reasons your air conditioner keeps tripping the circuit breaker.

February 21, 2020

The last thing you need on a hot Southern California summer day is for your air conditioner to keep tripping the circuit breaker and shutting off. While this is definitely annoying, keep in mind that your AC circuit breaker is a safety switch that protects your equipment from damage by turning off the power when an overload is detected. It also protects your safety since overloaded circuits can result in a fire. So if your AC circuit breaker keeps tripping repeatedly, this is not a situation you should ignore.

We cannot stress this enough: DO NOT keep resetting the breaker. Reset it once and only once. If the breaker trips again, then you have an issue that needs to be fixed. If the circuit breaker trips the second that your air conditioner turns on, then there is nothing more that you can do yourself – leave the circuit breaker off and call your local HVAC repairman. The problem has to do with wiring or a short circuit – something you don’t want to deal with.

Here are some possible reasons why your unit might be tripping the breaker:

Dirty A/C Air Filter: Dust can also collect on your A/C’s air filter. If you leave your air filter in so long that it is completely clogged with dirt, it can suffocate your AC, causing it to work much harder than it should, overheat, and trip the breaker.
Dirty A/C Condenser Coils : Your A/C condenser coils, located in the outside AC unit, are designed to release the heat from your home to the outside. Dirt, leaves and other debris can sometimes accumulate on the coils and prevent them from functioning properly, causing the air conditioner to overheat.
Condenser Coil Fan Problems : The condenser coil fan is responsible for cooling your outside A/C unit’s condenser coils. If the fan malfunctions, the coils will not be cooled and the unit will overheat and trip the circuit breaker.
A/C Refrigerant Level Too Low: Refrigerant is the chemical solution that enables the air conditioner to keep the air in your house cool. If your system has lost refrigerant, the air conditioner has to work harder to achieve the set temperature of the property. The refrigerant also keeps the compressor motor cool, so loss of refrigerant can lead to overheating of the compressor’s motor.
Loose Electrical Connections: If the electrical connections on your outside unit have come loose, usually through expansion and contraction due to contact with the weather, your breaker will likely trip. Tightening the connections is required if this is the problem.
Electrical Short: Another reason the breaker might trip is due to an electrical short somewhere in the system. When a short is present, the breaker will trip immediately. If this happens, it’s best not to reset the breaker and call for service.
Issues with the Circuit Creaker: The issue may not be with the AC itself but rather with the breaker. Wires connected to the breaker may be loose or the breaker itself may be bad and needs replacing. This is a relatively inexpensive fix.
Bad Capacitor or Compressor: The compressor is in your air conditioner’s outdoor unit. A weak compressor has trouble starting. When it does try to start, it may try to pull too much electricity, which will trip your breaker. If this is the problem, an air conditioning professional might recommend installing a hard start kit .
Motor Has Shorted: Electric motors in your AC can run for hours and hours and can take quite a bit of abuse. But if a motor runs hot for too long, the wire insulation can break down, leading to an electrical “short.” A “short” is where electricity bypasses its normal path, (so it’s taking a “shortcut”). This shortcut allows more electricity to flow than the wires can handle, causing the wires to overheat, melt and cause a fire. Of course, before the fire happens, the circuit breaker trips.
Grounded Compressor: A grounded compressor is the worst-case scenario on this list. Similar to a short, a grounded compressor occurs when an electrical winding within the compressor hits the side of the compressor. This causes a direct short to ground, which ignites the oil in the compressor and causes a burnout. Before this starts a fire, your circuit breaker will shut the electrical current off which is what causes your breaker to trip. The bad news is, if you have a grounded compressor, you will have to replace the compressor (an expensive part) or the whole outside unit. If your compressor is not covered under warranty and your outside unit is old, it may make more sense to replace the outside unit instead of the compressor. Contact an air conditioning expert to help you determine if you have a grounded compressor.

Troubleshooting

Reset your air conditioner’s circuit breaker (once, and only once)..

Always be careful with resetting a circuit breaker. If it keeps tripping, then something is wrong! Reset it once and only once, and see if your unit runs normally.

Always reset a circuit breaker by ensuring that it is fully in the OFF position first (if not, move it there), then turning it back ON. Wait and see what it does after a few minutes of running. If it does not trip again, then it might have been a power surge from a thunderstorm, or something like that.

Look at some of your other household equipment, such as your stove and microwave. If they are all have blinking and your air conditioner is also not working, then this probably is not a problem with your air conditioning system. If the circuit breaker trips the second that your air conditioner turns on, then there is nothing more that you can do yourself – leave the circuit breaker off and call your local HVAC repairman. The problem has to do with wiring or a short circuit – something you don’t want to deal with.

If You Are Still Having Problems

If you are still having trouble, you may need to give us a call to set up a consultation just to give you piece of mind.

Always work your way from the simplest and most common explanation to the more unlikely ones. Even if your air conditioner circuit breaker keeps tripping, be patient, and rule out the most likely causes. A lot of the time, it is something you could handle yourself, but if you need additional help, we would be happy to answer any questions you might have.

Look for any signs of damage or corrosion on the float switch and test its functionality according to manufacturer instructions.

By checking for a clogged condensate drain line and inspecting the float switch for malfunction, you can alleviate issues with your AC float switch tripping and maintain smooth operation of your air conditioning system without interruptions caused by water accumulation.

Inspect the Float Switch for Malfunction

Check if the float switch is malfunctioning by inspecting it for any signs of damage or irregularities. The float switch is an important component of your AC unit that helps prevent overflow and water damage. Here are some steps to follow in order to determine if the float switch is the cause of your tripping issue:

Check float switch wiring: Start by examining the wiring connections at the float switch. Ensure that they are secure and free from any loose or damaged wires.
Test float switch functionality: Gently lift the float arm to see if it moves freely and triggers a response from the AC unit. If it doesn’t, there may be a problem with the mechanism or sensor inside.

If you notice any visible damage such as corrosion, cracks, or water buildup on the float switch, it may need to be cleaned or replaced. Cleaning can usually be done by gently wiping away any debris with a soft cloth. However, if the damage appears severe or cleaning does not resolve the issue, replacing the float switch may be necessary.

By checking for any signs of damage and testing its functionality, you can determine whether your AC’s float switch is functioning properly. If you find that it needs cleaning or replacement, proceed to the next section about how to clean or replace the float switch without delay.

Clean or Replace the Float Switch

Take a moment to freshen up your AC’s float switch by giving it a thorough cleaning or swapping it out for a shiny, new replacement. Cleaning the float switch is crucial in maintaining its functionality and preventing any tripping issues. Start by disconnecting the power supply to ensure safety. Carefully remove the float switch from its housing and inspect it for any signs of debris or dirt buildup. Use a soft brush or compressed air to gently clean the switch, ensuring that all surfaces are free from any obstructions.

Why is my air conditioner tripping the circuit breaker?

July 6, 2017 by Michael C. Rosone | Last Modified: March 27, 2023

ac circuit breaker | ac circuit breaker keeps tripping

It’s the last thing you need on a hot summer day: your air conditioner keeps shutting off and the AC circuit breaker keeps tripping. You’re probably wondering what’s going on, and if there’s an easy solution. Do you need to call someone to fix the problem and if so, who should you call? The AC service company or an electrician?

Here’s the most important thing to know: your AC circuit breaker is a safety switch that protects your equipment from damage by turning off the power when an overload is detected. It also protects your safety since overloaded circuits can result in a fire. So if your AC circuit breaker keeps tripping repeatedly, this is not a situation you should ignore.

We can’t stress this enough: don’t keep resetting the breaker. You need to take action immediately to prevent expensive and potentially dangerous consequences.

AC circuit breaker tripping: WHAT TO DO FIRST

As we just mentioned, never keep turning it back on if the AC circuit breaker if it keeps tripping! You can follow the steps below once to make sure there really is a problem before continuing. Sometimes something like a lightning strike nearby can cause a one-time power surge that trips the breaker, and you’ll be fine once you turn it back on.

Here are the first steps to take when your AC circuit breaker trips:

Turn the air conditioning system OFF at the thermostat(s).
At your electrical panel, turn the AC circuit breaker switch to the ON position.
IMPORTANT: wait 30 minutes with the air conditioner OFF. Be sure that the thermostat remains OFF so that your air conditioner’s internal circuit breaker can reset. This can’t happen if the thermostat is signaling for cooling.
After 30 minutes, set your air conditioner back to COOL.

If you’re lucky, everything will work normally after this and the AC circuit breaker won’t trip again. You’re all set!

However, if the AC circuit breaker immediately trips again, or the AC won’t come back on, you have a problem that needs to be diagnosed and repaired by a professional. Read the next section for possible causes.

But what if your system seems to work ok for a little while, but then shuts off and trips the breaker again? If that happens, there’s one more thing you can try: changing your air filter. When your system filter is clogged with dust and debris, the fan motor must work harder and runs longer trying to draw air through the filter. In an attempt to do so, it may draw too much electricity and cause the AC circuit breaker to trip. Try replacing the filter to see if that makes a difference.

Possible reasons why your air conditioner is tripping the circuit breaker

From best-case to worst-case scenario, the most probable causes of your AC circuit breaker tripping include:

Power surge in the area (probably due to a thunderstorm)
Clogged air filter

Dirty condenser coil

Loose wire, short or electrical component failure, fan motor malfunction, frozen evaporator coil, refrigerant leaks, compressor failure.

We’ve covered the first 2, which you can handle on your own. The remaining issues are problems that it’s not safe to tackle yourself unless you are trained in how to work around high voltage electricity. This is a job for the professionals who not only know safety protocols but have the expertise to properly diagnose what’s wrong.

For problems causing your AC circuit breaker to trip, your best bet is to call in a qualified HVAC professional. Let’s go over the remaining causes and what you can expect when your service tech diagnoses one or more of these problems.

Have you been neglecting your yearly AC preventative maintenance? You may have also noticed that your system is not cooling as well as it used to. If so, a dirty condenser coil may be the culprit.

Your outside air conditioning unit has a condensing coil that does the job of releasing accumulated heat outside your building. Since it’s exposed to the elements (especially at street level or on a rooftop in the city) it can get coated with grime and debris. When that happens, heat transfer is impaired, causing your system to work harder to cool your space. Your condensing unit can draw too much power and cause the AC circuit breaker to trip.

Here’s the good news: a simple coil cleaning (done as part of a regular AC maintenance plan) can take care of this problem. Learn more from this related blog: AC Losing Its Cool? Try Air Conditioner Coil Cleaning

A power surge that trips the AC circuit breaker could be caused by a simple electrical issue within the air conditioner. A loose connection, a failed capacitor, or a short in the wiring could be responsible. Those issues can be fixed easily by a professional.

A clogged filter is just one reason that your air conditioner’s fan motor may be drawing too much power and causing the AC circuit breaker to trip. The fan blades might be coated with grime and slowing down the fan, putting a strain on the motor. A good cleaning may be enough to resolve the issue. Or, a malfunction within the motor itself may be responsible. In this case, your AC service technician will need to replace the fan motor.

If you have neglected maintenance for a long time, and you’ve got several of the problems listed above, eventually air flow is diminished within your system. That can cause the evaporator coil to freeze up, which draws excess power and can trip the AC circuit breaker. If you see ice on the coils of your inside AC unit, that’s what’s going on. In that case, be sure to keep the unit off and call in a professional right away. If you attempt to keep it running, your compressor may fail which is a very serious problem (read more about that below).

Learn more: AC Troubleshooting: FROZEN HVAC System? Don’t Let It Go

An older system (especially when maintenance has been neglected) can develop corrosion on the coils that leads to cracks, holes and leaking refrigerant. As the refrigerant level drops in your system, it has to work harder and run longer trying to cool your space. That can cause the unit to draw too much power and trip the AC circuit breaker.

If you’ve been noticing a slow decline in your system’s performance, this may be the cause. Your AC technician will need to find and fix any refrigerant leaks. Or, if they are numerous, replace the coil and/or refrigerant lines.

The compressor is the heart of your air conditioning system and a failed compressor might mean you need a whole new system. This is why you should never keep turning on the AC circuit breaker after it trips, or ignore any of the problems described above. Ultimately the strain on the system can lead to an expensive result: failure of the compressor.

As you may have noticed, many of the problems that cause the AC circuit breaker to trip can be avoided with regular air conditioning maintenance. A small investment once or twice a year (depending on your system’s usage) can save you from major headaches down the road. Learn more from these helpful resources:

Why Is My Air Conditioner Tripping The Circuit Breaker

The last thing you need on a hot, humid Summer day is for your air conditioner to stop operating.

When the circuit breaker trips it stops all power supply to the ac unit.

This is to protect the air conditioner from any further damage and potentially costly repairs.

AC circuit breaker tripping: WHAT TO DO FIRST

Locate your home's electrical panel.

You should be able to see if the circuit breaker is tripped.

Reset the circuit breaker and turn your air conditioner on again.

The ac unit may start and operate normally. If the breaker trips immediately, there is definitely a problem in the electrical system. Call us to diagnose and rectify the problem.

It Works for a While, Then Trips Again

This can be extremely frustrating. After resetting the breaker, your ac unit starts operating again. After a period of time, the circuit breaker trips again and the ac system stops operating.

You will need to call for an ac technician to attend, diagnose and rectify the issue.

Possible reasons why your air conditioner is tripping the circuit breaker

Power supply.

At times, there may be a drop in the power supplied to your premises. This is called a brown out. Your lights will dim and appliances will not operate correctly.

This may be caused by transmission problems, an electrical storm with lightning in the area as well as high demand.

If you air conditioner is trying to operate in these conditions, the current draw will increase and lead to the circuit breaker tripping.

There may also be a one time power surge which can also trip the breaker.

If you have three phase power supply, the loss of one phase will cause the breaker to trip

There is nothing that can be done until the correct power supply is restored.

Once power is restored, reset your circuit breaker and your air conditioning unit should operate normally.

Faulty Circuit Breaker

As with any electrical item, your ac circuit breaker can fail at times.

This may be due to an internal fault with it or loose electrical wiring at the terminals.

You will need to call a professional hvac technician to identify and repair or replace the circuit breaker.

A Dirty Air Filter

Dirty air filters impede the flow of air over the coil in the inside unit. The lack of sufficient air flow will increase the pressure on the indoor fan and slow it down.

The pressure on the fan causes the motor current to increase which can trip the ac unit circuit breaker

It is important to ensure your air filters are kept clean to reduce nuisance trips of your circuit breaker.

Insufficient Refrigerant

If your ac system is low on refrigerant, it will not cool to the conditions you require. It can also cause other problems.

The indoor coil can ice up and restrict the air flow the same as dirty filter will do.

The compressor will run hotter which increases the electrical current draw until the circuit breaker trips.

Frozen evaporator coil

This can occur due to a dirty air filter, insufficient refrigerant or expansion device being faulty

As per the dirty filter above, this can also be the cause of ac breaker trips.

Dirty Condenser Coils

The condenser coils are located in the outdoor unit. Dirt and leaves can be drawn into the coil to reduce the air flow.

Stacking items against the outdoor unit will also impede the air flow.

If this coil is dirty or blocked this will increase the load on the compressor causing the breaker to trip and can lead to compressor failure.

Loose wire, short or electrical component failure

Occasionally, wiring may become loose in their terminals. Loose wiring can create heat and lack of correct power supply to the components in the ac unit. In a worst case scenario, it may even start a fire. This will cause excessive current draw and trip the circuit breaker.

A short can be caused when the wiring insulation in a fan motor or compressor breaks down. The exposed wire may touch the casing of the motor and create a "short". This will instantly trip the circuit breaker.

Most of the components in your air conditioning system are electrically powered. At times, these may fail due to age, vermin and other adverse conditions. Failure of these can also cause the ac circuit breaker switch to trip.

Faulty Fan Motors or Compressor

All motors consist of electrical windings. When operating, the motors do get warm and after some time the wiring may break down.

If the wiring breaks down it can cause an open circuit or a short circuit. This will cause a circuit breaker trip and stop your air conditioner from operating.

What Can You Do To Help Prevent A Tripping Breaker

If there is an electrical storm in your area, turn off your air conditioning system.

Make sure that your air filter is clean at all times

Make sure your condenser coils are clean and that no items are stacked up against the condenser.

The most important thing you can do is have your air conditioner serviced regularly. This can alleviate the potential for some the above issues to occur.
