Possible Causes
Worn or cracked membrane keypad, Loose keypad ribbon cable, Failed user interface board, Moisture damage to control panel
How to Fix / Troubleshooting
Safety First: Unplug the microwave before removing the control panel.
- Test multiple keys: Note which keys work and which do not. Patterns (e.g., entire rows/columns) suggest a keypad matrix issue.
- Clean surface: Wipe the keypad with a soft, slightly damp cloth and dry thoroughly.
- Inspect ribbon cable: Remove the control panel and reseat the keypad ribbon cable on the control board. Check for corrosion or damage.
- Replace keypad/control panel: If keys remain unresponsive, replace the control panel assembly (membrane keypad). If the issue persists, the user interface or main control board may also need replacement.
