How to Fix / Troubleshooting
Safety: Unplug the microwave before any disassembly.
Door checks:
- Open and close the door firmly but gently. Avoid slamming, which can worsen alignment.
- Inspect the door latch hooks for wear, cracks, or looseness.
- Check that the door sits evenly and flush with the front of the microwave.
If dE persists:
- Remove the outer cabinet and inspect the door switch assembly and mounting bracket.
- Tighten any loose screws and ensure the bracket is not bent.
- Replace worn door latches or defective door switches as needed.
Warning: Do not attempt to adjust the metal door frame or cavity; improper alignment can cause microwave leakage.
