How to Fix / Troubleshooting
Safety: Unplug the microwave before working near the door switch area.
- Check door fit: Close the door and gently lift up and push down on the handle. Excessive play can cause intermittent switch contact.
- Inspect latch and hinges: Look for cracked latch hooks or loose hinge screws. Tighten or replace as needed.
- Door switch bracket: Access the switches and ensure the bracket is firmly mounted and not bent. Tighten screws.
- Replace faulty switches: Test each door switch with a multimeter. Replace any that do not change state reliably when the door is opened/closed.
Do not bypass or jumper door switches; this is extremely dangerous.
