Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave. Physical damage can compromise radiation shielding; proceed cautiously.
Steps:
- 1. Inspect exterior: Look for dents, cracks, or misalignment around the door frame and hinges.
- 2. Check door closure: Close the door slowly and observe if it rubs or catches. The gap around the door should be even.
- 3. Internal inspection (experienced DIYers): Remove the cabinet and inspect the door interlock bracket and surrounding metal for bending or cracks. Tighten any loose screws.
Important: If the cabinet or door frame is bent or cracked, the microwave should be replaced or professionally evaluated; do not attempt to bend it back into shape.
