Possible Causes
Bent or worn door hinges, Damaged door gasket, Misaligned door latch
How to Fix / Troubleshooting
Safety first: Ensure the oven is cool before working on the door. Support the door to prevent dropping.
Steps:
- Inspect gasket: Check the door gasket around the perimeter for tears, flattening, or missing sections. Replace if damaged.
- Check hinges: Open the door to the removal position (usually partially open) and lift it off the hinge arms. Inspect hinges for bending or wear.
- Replace hinges: If the door sags or does not align when reinstalled, replace the hinge arms and/or hinge receivers with OEM parts.
- Verify latch alignment: Ensure the door latch engages smoothly. Adjust the latch striker if the door does not pull in tightly.
Note: A poor door seal can cause temperature issues and trigger overheat faults.
