Carrier AC Unit Reset Button

Like restarting any appliances when there’s a problem, sometimes your Air Conditioner needs a reset too. In many cases, your AC will start to function normally again after a reset. Read on to know more about resetting your Carrier AC unit and where the reset button is located.

Why Do You Need to Reset?

There are a few reasons why you would want to reset your Carrier Air Conditioner unit. But the main reason is that the circuit breaker is engaged and isn’t allowing the compressor to start. A circuit breaker is a safety device that protects your AC unit by immediately shutting it down when an overload is detected.

You recently experienced a power outage. Once the electric power is ON after an outage, the sudden jump in electrical voltage can cause an overload in your unit’s circuit. These may also cause your unit to have more issues.

The thermostat in your home is malfunctioning. Sometimes, no matter how many times you reset your Carrier AC, it simply comes down to a faulty thermostat. It’s not tough work, and I’m sure you could finish it in an hour or two.

Where Is The Reset Button on a Carrier Air Conditioner?

Carrier air conditioning units usually will have a reset button on them. You can find the reset button inside the air conditioner’s compressor.

The button is red in color and fairly small in size. It should be marked clearly as a “RESET BUTTON.” To easily find your Carrier AC reset button, consult your unit’s instruction manual.

How to Reset Your Carrier AC system

Resetting your Carrier AC unit with a reset button is so easy. Press and hold the reset button for three seconds before releasing it. Your air conditioning unit will respond with three beeps, and it should reset the system immediately.

That’s it, you’ve reset your Carrier air conditioner.

If your air conditioner doesn’t have a reset button, you need to reset it manually through the circuit breaker. Look for the breaker that is linked to your AC unit and turn it off and on. The circuit breakers are usually located in the basement, closets, or crawl spaces.

Don’t attempt to reset your unit again and again!

If the unit still isn’t working as it should after reset, you may have an issue with your air conditioner. If your circuit breaker is tripping over and over or your unit needs to be restarted frequently, it is time to call a professional.

Some other potential issues you may have include:

  • Clogged air filter
  • Faulty wiring
  • Fan motor issues
  • Compressor failure


Resetting your AC unit is often the solution to some air conditioner problems. It’s easy once you know the Carrier AC unit reset button location. But sometimes, there are some situations that you should not attempt to fix yourself. In these cases, you should call for a professional HVAC technician to get to the root of the problem.

You should also maintain your air conditioning unit regularly to ensure it functions well. A poorly maintained air conditioner will develop problems more frequently.
