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.

The Carrier AC reset button might seem like a mysterious component, but it serves an essential purpose in safeguarding your AC system. Its primary function is to protect your system from minor disruptions, acting like a reset button on your computer when things go wrong.

Imagine a situation where your AC experiences a hiccup due to a sudden power fluctuation or a temporary glitch. Instead of panicking, the reset button comes to the rescue. It allows the system to reset itself, giving it a chance to recover and restore normal operation.

Why Do You Need to Reset?

Let’s paint a picture with a couple of everyday scenarios to help you understand when the Carrier AC reset button can be a lifesaver. There are a few reasons why you would want to reset your Carrier Air Conditioner unit.

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.

When to Use the Reset Button

While the Carrier AC reset button is indeed a helpful tool, it’s not your first line of defense when your AC is acting up. Before resorting to the reset button, make sure to perform some basic checks.

  1. Thermostat Settings – Ensure that your thermostat is set to the desired temperature and cooling mode. Sometimes, a simple adjustment is all it takes to get your AC back on track.
  2. Power Supply – Double-check that your AC unit has a steady power supply. A blown fuse or a tripped circuit breaker could be the culprit, and resolving this issue might bring your AC back to life.
  3. Air Filter Condition – A clogged air filter can hinder your AC’s performance. If it’s dirty, clean or replace it as needed. This simple step might solve the problem without the need for a reset.

If these checks don’t resolve the issue and your AC is still acting up, that’s when the reset button becomes your next step.

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

The Importance of Professional Maintenance

While the Carrier AC reset button is undoubtedly a helpful tool, it’s essential to recognize its limitations. If you find yourself needing to reset your AC frequently, or if you notice persistent issues such as strange noises or leaks, it’s time to call in the professionals.

Regular AC maintenance is a game-changer, ensuring your system’s longevity and optimal performance. A qualified technician can identify underlying issues, perform necessary repairs, and provide preventive maintenance that can save you from costly breakdowns in the future.


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.
