McQuay Air conditioner remote control not working

If your McQuay air conditioner remote not working issue started suddenly, begin with the simple checks before assuming the unit has a major control problem. Weak or dead remote control batteries are the most common cause, so install fresh batteries first and make sure the battery contacts are clean and positioned correctly. If the air conditioner still responds to the control panel buttons but the air conditioner is not responding to remote commands, the remote control itself may be defective and need replacement. If a known-good remote still does not operate the unit, the next likely problem is the main control board, which contains the infrared receiver that picks up the remote’s signal. When that receiver fails, the AC remote control not working symptom can look exactly like a bad remote. RepairClinic.com can help you match the right McQuay remote control or main control board to your unit. Enter your model number to find the exact replacement part made to fit your specific air conditioner.

01 - McQuay 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 - McQuay 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.
