How to Fix / Troubleshooting
Safety: Unplug the microwave before adjusting door components.
- Step 1 – Check for obstructions: Inspect the door seal area for food debris or objects preventing full closure. Clean the gasket and frame.
- Step 2 – Test door closure: Close the door firmly and check that it sits flush with the cabinet. If it bounces back or feels loose, the hinges or latch may be worn.
- Step 3 – Inspect latch and switches: Remove the outer cabinet and locate the door latch and interlock switches. Ensure the latch hooks fully engage the switch levers when the door is closed. Adjust the latch bracket if possible or replace worn parts.
- Step 4 – Test door sensing switch: Use a multimeter to test the door sensing switch for proper operation (changes state when door opens/closes). Replace if faulty.
Do not operate the microwave if the door does not close securely; this is a critical safety issue.
