How Do You Reset an Air Conditioner?

ByRalph P. Sita Updated onJanuary 20, 2025

If your air conditioner isn’t starting up, resetting it could solve the issue quickly. Resetting an air conditioner is a simple, straightforward process that can often be completed in just a few minutes. To begin, locate the reset button, typically found near the power cord or control board of your unit. Once located, press and hold the reset button for about three seconds. After releasing the button, press the power button to turn the air conditioner back on. If the unit powers up normally, the reset was successful. However, if the air conditioner still fails to start, it may require professional assistance for further troubleshooting.

How Do You Reset an Air Conditioner?

If your air conditioner isn’t working as well as it used to, it may be time for a reset. Here’s how to do it:

1. Turn off the power to the unit at the breaker box.

2. Remove the front panel of the air conditioner.

3. Locate the reset button on control board inside the unit. It will usually be red or black, and may have a small hole next to it.

4. Press and hold the reset button for 3-5 seconds, then release it.

5. Replace the front panel and turn on the power to the unit at the breaker box.

6. Set your thermostat to its desired temperature and wait for the air conditioner to cool your home.

What Should You Do If Your Air Conditioner Stops Working?

If your air conditioner stops working, you should first check to see if the unit is receiving power. If it is not, you will need to check the fuse box or circuit breaker to see if a fuse has blown or the breaker has tripped. Once you have determined that the unit is receiving power, you should check the thermostat to make sure it is set properly.

If it is not, adjust it accordingly. If the unit still does not turn on, you may need to call a professional for assistance.

How Often Should You Have Your Air Conditioner Serviced

As the weather starts to heat up, many of us begin to think about firing up the air conditioner. But how often should you have your air conditioner serviced? The answer may surprise you – most experts recommend that you have your air conditioner serviced at least once a year, and preferably in the springtime before the really hot weather hits.

That way, if there are any problems with your AC unit, they can be detected and repaired before they cause any major issues. Of course, if you live in an area with very high temperatures (such as the desert Southwest), or if your AC unit gets a lot of use, you may need to have it serviced more frequently. And if you notice any strange noises or smells coming from your AC unit, or if it doesn’t seem to be cooling as efficiently as it used to, don’t wait until next year – call for service right away.

In short, play it safe and schedule an annual AC tune-up. Your air conditioner will thank you for it!

Next Steps

If your air conditioner is blowing warm air, it may be time to reset it. To do this, first make sure that the unit is turned off. Next, locate the reset button on the control panel.

Once you have found the button, press and hold it for three seconds. After a few moments, you should hear a click which indicates that the reset process is complete.
