Possible Causes
Misaligned door latch, Worn door hinges, Faulty door interlock switch, Bent door frame or cabinet
How to Fix / Troubleshooting
Safety: Unplug the microwave before adjusting door components.
Steps:
- 1. Check for obstructions: Inspect the door seal area for food debris or foreign objects preventing full closure. Clean the gasket and frame with a damp cloth.
- 2. Inspect hinges: Open the door halfway and gently lift it. Excessive play indicates worn hinges or loose hinge screws. Tighten accessible screws.
- 3. Examine latch hooks: Ensure the plastic latch hooks engage smoothly into the cabinet. If cracked or bent, the door assembly may need replacement.
- 4. Test closure: Close the door firmly but not forcefully. If dE disappears when the door is pressed inward, the interlock switches may be misaligned.
- 5. Adjust or replace interlock assembly (for trained persons): Remove the cabinet and adjust the door switch bracket so that all switches actuate fully when the door is closed. Replace any damaged switches.
Do not operate the microwave with a faulty door system; it is a critical safety component.
