We hear Phoenix-area homeowners ask, “Why does my air conditioner keep tripping the breaker at the control panel?” First off, if this keeps happening then don’t turn the circuit back on. The circuit breaker’s job is to keep your home and appliances safe by shutting off the flow of electricity when the current flow gets too high. If it keeps tripping, something needs to be fixed. If the air conditioner is the source of the tripping, it may be overheating. When an air conditioner overheats, it draws more amps (a measurement of electrical current) from the circuit. That may be pushing the circuit past the number of amps it was meant to handle. So the breaker usually trips after the air conditioner has been running for a while. So now we need to know what’s causing your air conditioner to overheat. Common causes include:
These certainly aren’t all the reasons that can cause the circuit to trip the breaker. But they are some common ones that you can see.

Now let’s look at the specific causes of an AC tripping the breaker. Specific AC problems that can trip your breakerDirty air filterIf 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 coilsThese 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 capacitorA 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 compressorThe 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 connectionsWires 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 problemThere are numerous small mechanical problems that could also be causing your AC to trip your breaker.
