How to Fix / Troubleshooting
Safety: Unplug the microwave before any mechanical adjustments.
- Check door closure: Open and close the door firmly. Ensure nothing is trapped in the door seal area.
- Inspect latch hooks: Look at the plastic hooks on the door edge. If one is cracked or missing, the door will not actuate the switches correctly.
- Check hinges: Verify that the door is level and not sagging. Tighten hinge screws if accessible.
- Test with gentle pressure: While attempting to start, gently push on the door near the latch side. If it starts, the latch or switches need adjustment or replacement by a technician.
