GE air conditioner display and buttons work, but unit does not respond to remote control

Steps:

• Replace batteries: Install fresh, correct-type batteries in the GE remote and ensure they are oriented properly.
• Check line of sight: Aim the remote directly at the control panel from within the recommended distance. Remove any obstructions.
• Test remote: Point the remote at a smartphone camera; pressing buttons should show a flashing light on the camera screen. If not, the remote is likely bad and should be replaced.
• IR receiver: If the remote works but the unit does not respond, the IR receiver on the control panel may have failed. Replace the display/control panel assembly that includes the IR sensor.
