Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave before working on the control panel.
Immediate steps:
- Unplug the unit for 10–15 minutes to reset the control. If SE returns immediately, proceed to inspection.
- If the error appeared after cleaning, ensure no liquid is trapped around the keypad. Allow the panel to dry thoroughly.
Keypad inspection:
- Remove the control panel assembly.
- Disconnect the keypad ribbon cable from the control board, inspect for corrosion, cracks, or burnt spots.
- If the keypad overlay is bubbled, cracked, or certain keys are always active, replace the keypad or entire control panel assembly.
Control board check: If a new keypad does not resolve SE, the control board is likely defective and should be replaced by a technician.
