How to Fix / Troubleshooting
Safety: This condition can be hazardous. Unplug the microwave immediately and do not use it until repaired.
Steps:
- 1. Inspect door movement: Ensure the door opens and closes smoothly and is not binding.
- 2. Test door switches: Access the door switch assembly and test each switch for proper operation with a multimeter. Replace any switch that remains closed when it should be open.
- 3. Check control board: If switches test good, the control board relay controlling the fan/light/turntable may be stuck and the board will need replacement.
