How to Fix / Troubleshooting

Safety first: Use oven mitts when touching the door during or after cooking. Unplug and cool before inspection.

  • Step 1 – Inspect gasket: Check the door gasket/seal for cracks, gaps, or flattening. Replace if damaged.
  • Step 2 – Check door closure: Ensure the door closes evenly and latches securely. Adjust hinges or latch if needed.
  • Step 3 – Internal shields: Verify that any internal heat shields or baffles are in place and not bent away from the door area.
  • Step 4 – Insulation: If the exterior around the door is excessively hot and insulation appears burned or missing, have a technician evaluate and replace the cavity insulation if necessary.
