How to fix it

  1. Unplug or shut breaker for 5+ minutes — sometimes the lock motor finishes its travel on power restore.
  2. Inspect door, hinges, and latch for charred debris; clean gently around the latch.
  3. Start and then cancel a Self Clean cycle to drive the motor through its full travel.
  4. Remove the top panel and visually inspect the door lock assembly and its wiring.
  5. Test the lock motor and microswitches with a multimeter against Samsung's resistance specs.
  6. Replace the door lock assembly if mechanically failed or open-circuit.
  7. If lock and wiring test good, replace the main control board.
