How to Fix / Troubleshooting

Safety first: Ensure the unit is unplugged before any physical adjustment of the door.

Steps:

  • Check for obstructions: Inspect the door gasket and frame for food debris or foreign objects preventing full closure. Clean with a damp cloth and dry thoroughly.
  • Close firmly: Open and close the door several times with a firm push to ensure the latches engage.
  • Check door sag: Gently lift the door while closed. Excessive play may indicate worn hinges.
  • Test: Plug back in and attempt a short cook cycle. If dE persists, a switch may be faulty.

Technician repair:

  • Test the door interlock switches and replace any defective ones.
  • Adjust or replace the door hinges or latch assembly if misaligned.
