How to Fix / Troubleshooting
Safety First: Unplug the microwave. Door switch circuits are interlocked with high-voltage components; improper repair can be dangerous.
- Check door operation: Open and close the door firmly. Listen for distinct clicks from the door switches. A missing click can indicate a failed or misaligned switch.
- Inspect latch and hinges: Look for cracked latch hooks or sagging door that may prevent switches from actuating fully.
- Access switches: Remove the control panel and, if necessary, the upper cover to access the door switch cluster on the latch side. Do not disturb high-voltage wiring.
- Test switches: Using a multimeter, test each door switch for proper continuity (NO/NC) according to the wiring diagram. Replace any switch that does not change state when the door is opened/closed.
- Check mounting bracket: Ensure the switch bracket is not cracked or loose. Replace the bracket if it allows switches to move.
