Amana air conditioner remote control does not operate the unit; unit works from front panel only.

Safety first: No internal electrical work is needed for basic checks; unplug only if opening the unit.

Steps to restore remote operation:

• Replace batteries: Install fresh, correctly oriented batteries in the remote.
• Check line of sight: Ensure there is a clear path between the remote and the IR receiver window on the unit.
• Test remote: Point the remote at a smartphone camera and press buttons; you should see the IR LED flash on the screen. If not, replace the remote.
• Inspect IR receiver: If the remote works but the unit does not respond, the IR receiver on the control board may be faulty. Replace the control board or IR receiver module as designed for your model.

Keep the IR window on the unit clean and free of stickers or tape that can block the signal.
