Samsung Oven C-d1 — Door Lock Malfunction
Samsung Oven · Error code C-d1
What C-d1 Means
The door lock motor/assembly didn't reach the expected locked or unlocked position within the allowed time. Most often triggered during or right after a Self Clean cycle.
Symptoms
- C-d1 displayed, oven door stays locked
- Lock motor hums but latch doesn't move
- Self Clean won't start or won't end
- Door reports closed but bake won't start
Common Causes
After Self Clean, expansion or charred food can jam the latch hook.
Motor or microswitch in the latch assembly has burned out.
Mechanical linkage has bent or come off.
Pinched/burned wire between main PCB and door lock.
PCB isn't reading the latch position switch correctly.
How to Fix It
- Unplug or shut breaker for 5+ minutes — sometimes the lock motor finishes its travel on power restore.
- Inspect door, hinges, and latch for charred debris; clean gently around the latch.
- Start and then cancel a Self Clean cycle to drive the motor through its full travel.
- Remove the top panel and visually inspect the door lock assembly and its wiring.
- Test the lock motor and microswitches with a multimeter against Samsung's resistance specs.
- Replace the door lock assembly if mechanically failed or open-circuit.
- If lock and wiring test good, replace the main control board.
