How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing the control panel.
- Dry out moisture: If SE appeared after heavy steam cooking, unplug the unit and leave the door open for several hours to allow moisture to evaporate.
- Clean keypad surface: Wipe the keypad with a dry cloth. Avoid spraying cleaners directly on the panel.
- Inspect ribbon cable: Remove the control panel and check the keypad ribbon for signs of moisture, corrosion, or damage. Reseat the connector.
- Replace keypad: If SE persists, replace the membrane keypad/control panel assembly.
- Control board: If a new keypad does not resolve SE, the main control board may be defective and require replacement.
