How to Fix / Troubleshooting
Safety first: Unplug the microwave. Door interlock circuits are critical safety components.
- Check door closure: Ensure the door closes firmly and evenly.
- Listen for clicks: You should hear multiple clicks as the door closes. Missing clicks suggest a switch is not actuating.
- Access switches: Remove the outer cabinet and control panel to reach the door switch assembly. Inspect for loose mounting or broken actuators.
- Replace switches: Replace any defective door interlock switches and adjust the latch bracket so all switches operate correctly.
