Possible Causes
Worn touch membrane, Moisture behind control panel, Damaged ribbon cable, Faulty control panel PCB
How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing the control panel.
- Dry out moisture: If the issue started after cleaning or heavy steam use, leave the door open and allow the unit to dry for several hours.
- Clean panel surface: Wipe gently with a dry or slightly damp cloth; avoid excessive moisture.
- Reseat ribbon cable: On accessible models, remove the control panel screws, tilt the panel forward, and reseat the flat cable between the keypad and main board.
- Test keys: After reassembly, test all keys. If some remain unresponsive, the touch membrane or panel PCB likely needs replacement.
Warning: Do not use sharp objects on the keypad; this can puncture the membrane.
