If your Sharp air conditioner remote is not working, start with the simple checks before replacing parts. Weak or dead remote control batteries are the most common reason a Sharp air conditioner stops responding to remote commands, so install fresh batteries first and make sure they are seated correctly. If the unit works from the control panel but the air conditioner is not responding to the remote, the remote control itself may be defective, especially if only some buttons work or the display is inconsistent. The next likely cause is the main control board. On many Sharp window AC models, the main control board includes the infrared receiver that picks up the signal from the remote, and if that receiver fails, even a good remote will not communicate with the air conditioner. Whether you need a Sharp AC remote control, main control board, or related part, enter your model number on RepairClinic.com to find the exact replacement part for your specific air conditioner.
01 - Sharp 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.

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.
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.
