Camry air conditioner powers on but does not respond to remote control commands

Safety first: No high-voltage work is required for basic checks; keep fingers away from live parts.

• 1. Replace batteries: Install fresh, correctly oriented batteries in the Camry remote.
• 2. Check remote output: Point the remote at a smartphone camera and press a button; you should see a flashing light on the camera screen if the IR LED is working.
• 3. Clear line of sight: Ensure nothing is blocking the IR receiver window on the indoor unit and clean it with a soft cloth.
• 4. Try manual controls: Use the emergency ON/OFF button on the indoor unit (if provided). If this works, but the remote does not, suspect the remote or IR receiver.
• 5. Replace IR receiver: If a known-good remote still does not control the unit, the IR receiver module on the indoor PCB may need replacement by a technician.
