How to Fix / Troubleshooting
Safety first: Unplug the microwave before cleaning or pressing on the keypad.
Steps to improve keypad response:
- 1. Clean surface: Wipe the keypad with a soft, slightly damp cloth and mild detergent. Dry thoroughly.
- 2. Test pattern: Note which keys fail. If an entire row or column of keys does not work, the ribbon cable or controller is suspect.
- 3. Dry out moisture: If the panel was exposed to steam, leave the door open and allow several hours to dry before retesting.
- 4. Power reset: Unplug for 5 minutes, then plug back in.
If keys still fail: The keypad membrane or control panel assembly must be replaced by a technician.
