Possible Causes
Faulty door switch, Misaligned door latch, Broken door switch actuator, Control board input failure
How to Fix / Troubleshooting
Safety: Unplug the microwave before inspecting door components.
Checks:
- Open and close the door slowly and listen for distinct clicks from the door switches. A missing click can indicate a failed or misaligned switch.
- Inspect the door latch hooks for cracks or wear.
- Check that the door closes evenly and fully against the front frame.
Technical steps:
- Access the door switch bracket by removing the control panel and inner trim.
- Test each door switch with a multimeter for proper open/closed operation as the door moves.
- Replace any defective switch or damaged latch bracket.
- If switches and latch are good, the control board door input circuit may be faulty and require board replacement.
After repair, verify that the interior light comes on with the door open and that the unit starts only when the door is fully closed.
