How to Fix / Troubleshooting
Safety: Unplug the microwave before inspecting the door area or internal wiring.
User-level checks:

Technician-level checks:
- 2. Inspect door switches and wiring: Look for chafed wires near the door latch that may short when the door moves.
- 3. Check fuse and thermal cut-outs: Ensure they are firmly seated and not loose in their holders.
