Carrier Air conditioner remote control not working

If your Carrier air conditioner remote control is not working, start with the simple stuff first. Weak or dead remote control batteries are the most common reason a Carrier AC stops responding to the remote, so install fresh batteries and make sure they are positioned correctly. If the air conditioner works from the unit’s control panel but does not respond to the remote, or only some buttons work, the remote control itself is likely defective and should be replaced. If a new or known-good remote still does not operate the unit, the problem may be the main control board. The board receives the remote’s infrared signal through its receiver, and if that receiver fails, the air conditioner cannot communicate with the remote. This can make it look like a window AC remote is not working when the control board is actually at fault. Enter your Carrier air conditioner model number on RepairClinic.com to find the exact remote control, main control board, or related replacement part that fits your specific unit.

01 - Carrier 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 - Carrier 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.
