My AC Remonte's Not Working

If your air conditioner remote not working issue started suddenly, begin with the simple stuff: weak or dead batteries are the most common cause, even if the remote display still lights up. Install fresh batteries and make sure the unit responds from a reasonable distance with nothing blocking the signal. If the air conditioner works normally from the control panel but the AC remote control not working problem continues, the remote control itself is likely defective and should be replaced. On some units, the problem is not the remote at all. The main control board includes an infrared receiver that accepts the remote’s signal, and if that receiver fails, the air conditioner will not respond to remote commands. A window AC remote not working can usually be narrowed down by testing whether the manual controls still operate cooling, fan speed, and mode settings.

01 - Air Conditioner Remote Control

First, try replacing the batteries in the remote control. If installing fresh batteries doesn’t solve the problem and you can still operate the air conditioner manually, the remote control might be defective. If you think the remote control is defective, replace it.

02 - Air Conditioner Main Control Board

The main control board has an infrared receiver that receives signals from the remote. If the infrared receiver is not working, the remote control will not be able to communicate with the control board. If you suspect the main control board is defective, replace it.

03 - Weak or Dead Remote Control Batteries

The remote control is powered by batteries which may have become too weak for the control to work. Replace the batteries with new ones to see if that resolves the issue.

04 - Replace remote control

If the unit responds correctly when the control panel buttons are pressed, but does not respond to the remote control, or only certain functions of the remote control, the remote is likely defective and will need to be replaced. Refer to owner's manual for guidance.
