Many of the best air conditioners operate on electronics similar to computers. And just like rebooting a computer can help solve many issues, the same applies to window AC units. So that’s why we’re going to explain how to reset a window air conditioner.

KEY TAKEAWAYS:

  • Resetting a window AC reboots the electrical components and can solve any power distribution glitch.
  • Most window ACs don’t have a reset button and will have to be reset manually.
  • Unplug the AC, and then turn off the power at the circuit breaker.
  • After about 30 minutes, turn everything back on and check if it worked.

And for those languishing in the summer heat, you need to ensure that your AC unit is in top condition. So for further reading, check out our guide on how to refill freon on a window air conditioner.

How to Reset a Window Air Conditioner

Knowing how to reset an air conditioning unit is a common practice that every owner should know, whether you use a window unit, portable unit, or central cooling system. Just like understanding the importance of how to seal gaps around a window air conditioner, a reset is an easy task that can potentially fix several AC errors.

STEP 1

Check if your window AC has a reset button. If it does, you can press that. However, most window ACs come without a reset button.

STEP 2

Turn the air conditioning unit off by switching off the power button on the control panel. If your AC doesn’t turn off via the control panel, you’ll have to unplug it from the power supply.

STEP 3

If you are resetting because of power outages, go to the circuit breaker box that connects to the AC’s wall outlets. Then, open the breaker box and turn off the corresponding switch. Leave the switch off for about 20-30 minutes.

STEP 4

Turn the breaker switch, close the electrical panel, and return to the window unit.

STEP 5

Plugin the window air conditioning unit and power it on. Test to see if everything is running as it should

STEP 6

If things are still running poorly, contact an air conditioner repair technician for help.

Warning

Always keep an eye to ensure your window unit isn’t overheating. Window units are the most likely AC system to catch on fire.

F.A.Q.S

What are the best ways to properly maintain my window air conditioner?

The best way to keep a healthy window AC unit is to clean the air filter. Another great thing to do is store the unit in a dry cardboard box in a room that doesn’t get below freezing during the wintertime.


What does the filter reset mean on an air conditioner?

The filter reset light indicates that you need to clean or replace your unit’s air filter.


What do I do if my AC won’t turn off?

This problem is commonly attributed to having a bad temperature sensor. If you find that your unit won’t turn off, unplug it and let it rest for a while before plugging it back in.


STAT: The Department of Energy states that 78 degrees are the best temperature to maintain a balance of comfort and energy efficiency. (source)
