How to Fix / Troubleshooting

Safety: Unplug the microwave.

If the door feels loose or misaligned, inspect hinges and latch.

Internal checks:

Remove the outer cabinet and inspect the door switch bracket for looseness or damage.
Test each door switch with a multimeter to ensure they change state correctly as the door moves.

Corrective actions:

Tighten or replace a loose or warped door switch bracket.
Replace any door switch that does not operate reliably.
