Possible Causes

Faulty door switch, Misaligned door latch, Broken latch hook, Damaged wiring to door switch

How to Fix / Troubleshooting

Safety: Disconnect power before working on the door or switch assembly. Avoid slamming the door, which can worsen alignment.

  • 1. Check door alignment: Ensure the door closes evenly on both sides and that the hinges are not bent.
  • 2. Inspect latch hook: Look at the metal latch hook on the door and the catch in the frame. If bent or worn, it may not actuate the switch fully.
  • 3. Access door switch: Remove the top or front trim to access the door switch assembly near the latch area.
  • 4. Test switch: With power off, disconnect the switch and test continuity while pressing and releasing the actuator. Replace if it does not change state reliably.
  • 5. Check wiring: Inspect the harness from the switch to the control board for breaks or loose connectors.
  • 6. Adjust latch: If the latch is slightly misaligned, adjust mounting screws or replace the latch hook to ensure proper engagement.
