Why is my AC tripping the breaker?

I recently found in my father’s room that his air conditioner cooled down for a while before tripping the circuit breaker and turning it off. I attempted to reset it, but it persisted. I thus researched for the split AC MCB tripping. I found that it could occur as a result of the circuit becoming overloaded. Additionally, I came across other common causes that I have listed below for your reference.

Reasons for AC MCB Switch Tripping

There are several typical causes I found for MCB tripping when AC compressor starts. Most of them are already mentioned by Ruan. Moreover, there are other 2 factors that can cause the tripping issues:

Bad Capacitor

Air conditioner runs on a capacitor that helps it to get started and keeps it going. If it draws excessive power, then it will trip your AC MCB. To stop additional harm to the device, you have to get the capacitor inspected by an HVAC technician and replaced if necessary. 

Electrical Short

I also came to know that the electrical motor in the air conditioner may melt wire insulation if it heats up too quickly. It could result in an electrical short and perhaps ignite a fire. To fix this issue, it’s necessary to get the breaker serviced and repaired if it trips.

I finally hired a professional AC technician and got it fixed. I hope this helps you get an idea of the reasons behind AC tripping and how do I stop my AC from tripping the breaker.

I discovered my AC was tripping the breaker last summer. To have it fixed, I called my friend, an AC technician, and I asked him why did my AC trip the breaker. He said that the circuit breaker was not providing my air conditioner with enough electrical current. He fixed it and also informed me of many potential reasons why AC keeps tripping. Read on to know more.

Why Does My AC Keep Tripping the Breaker?

It might be annoying and inconvenient to have your air conditioner frequently trip the breaker. My friend informed me of the following common reasons and their solution:

• Faulty Compressor

The compressor is the main component of your AC system. When it first starts, a lot of electricity is required. The issue is that as the compressor becomes old, it becomes more difficult to start and requires more electricity. This in turn trips the breaker. To avoid more problems with the breaker, you'll need to hire a specialist and get it replaced.

• Faulty Circuit Breaker

The breaker itself sometimes might not be able to support the AC unit's electrical needs if it is malfunctioning or outdated. In this instance, replacing the breaker is necessary to make sure it is operating correctly.

• Loose Wiring

The AC tripping the breaker may also occur if the wiring in your house is outdated or broken in some other way. Hire a professional who can rewire your circuit and maybe replace the metal plate holding all of your wires to fix this issue.

• Dirty Air Filter

The AC unit works harder due to the airflow restriction. All you need to do is change the filter. This is the most common reason why

does AC breaker keep tripping.

• Shorted Motor

When the motors run for an extended period of time, the wire insulation may break down, and cause an electrical short. This results in the trip of a circuit breaker. To fix it, call an AC expert.

I hope you got an idea of why did my AC trip the breaker.

Hey,

Isn't it annoying if you keep experiencing AC tripping problems? The room doesn't get cold, extra electricity is consumed by the air conditioner. In some cases, the AC stops working altogether. I will share with you some of the words of wisdom shared by my electrician.

The MCB will trip when there is an electricity overload detected. Sometimes, you will experience a power surge in the area. Any loose wire and electrical component failure can lead to the MCB tripping as well.

Here are a few of the possible reasons :

• Clogged air filter 

• Dirty air filters make it difficult for the AC to run at its best frequency. 

• Dirty condenser coil

• Fan motor malfunction

• Frozen evaporator coil

• Refrigerant leaks

• Compressor failure

The breaker stops the flow of electricity to the equipment when it is not possible to do so manually. In my house, the AC trips the breaker when the generator is unable to handle the load of many heavy-duty appliances such as refrigerator, chimney, geyser etc.

Now that you know why my AC is tripping. Let me share a quick and easy solution. You can get a stabiliser for your AC. It will ensure, your AC gets a constant flow of power all day and doesn't trip when electricity is not stable.
