Possible Causes
Worn membrane keypad, cracked control panel overlay, moisture intrusion, loose keypad ribbon cable, failed user interface board
How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing the control panel.
- Test all keys: Note which keys work and which do not. If entire rows or columns fail, the keypad matrix is likely damaged.
- Dry the panel: If the issue started after cleaning, leave the door open and allow the panel to dry for several hours.
- Inspect ribbon cable: Remove the control panel and reseat the keypad ribbon cable on the control board.
- Replace keypad/control panel: If keys remain unresponsive, replace the control panel / keypad assembly with the correct Monogram part.
