Rheem Air conditioner remote control not working

If your Rheem air conditioner remote not working problem leaves the unit stuck on its last setting, start with the simple checks before replacing parts. Fresh batteries are the first move, since weak or dead remote control batteries can make the AC remote control not working even when the air conditioner itself is fine. If the Rheem air conditioner responds normally from the control panel but the air conditioner is not responding to remote commands, the remote control is the most likely failed part and should be replaced. If a known-good remote still will not operate the unit, the issue may be the main control board, which uses an infrared receiver to read the remote’s signal. A failed receiver means the remote cannot communicate with the board. RepairClinic.com can help you match the correct Rheem remote control or main control board to your unit. Enter your model number to find the exact replacement part made for your specific air conditioner.

01 - Rheem 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 - Rheem 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.
