Possible Causes
Defective membrane keypad, Faulty touch control PCB, Moisture ingress behind control panel, Loose ribbon cable between keypad and main PCB
How to Fix / Troubleshooting
Safety: Unplug the microwave before removing any panels.
User-level steps:
- Power reset: Disconnect power for 5 minutes to reset the control electronics.
- Dry the control area: If steam or liquid has recently contacted the control panel, gently wipe it dry and allow it to air dry for several hours before retesting.
- Check for stuck keys: Press each button individually. If any key feels stuck or does not click, the keypad may be damaged.
Technician-level steps:
- Remove the control panel assembly to access the keypad ribbon cable.
- Reseat the ribbon cable into the main control board connector.
- Test the membrane keypad matrix with a multimeter or keypad tester; replace if certain keys do not register.
- If the keypad tests good, replace the touch control PCB (user interface board).
Keypad and control board replacement are low-voltage tasks but still require care and correct part matching by model number.
