Samsung Oven Error Code C-d1 — Door Lock Assembly Short/Misposition
What this means
The C-d1 error code indicates the oven's door lock assembly is either electrically shorted or mechanically stuck in the wrong position. The door lock engages during self-cleaning cycles to prevent the door from being opened at high temperatures. When the lock assembly malfunctions, it can trigger this error and prevent oven operation, particularly self-clean functions.
Alternate codes: Cd1, C-D1
Step-by-step fix
4 stepsPower cycle the oven
Turn off the oven at the circuit breaker for 5 minutes, then turn it back on. The door lock motor may re-home itself.
If the door is stuck locked, the breaker reset may allow it to unlock.
Check the door lock position
Look at the top of the oven opening to see if the lock arm is in the locked or unlocked position. If it is partially engaged, it may be stuck.
Never force the lock mechanism — this can break the assembly.
Test the door lock assembly
Unplug the oven, remove the top cover, and locate the door lock assembly. Test the lock motor and switches with a multimeter for continuity.
The lock assembly typically has a motor and two position switches (locked and unlocked).
Replace the door lock assembly if faulty
If the lock motor or switches fail testing, replace the entire door lock assembly. Disconnect the wire harness, remove the mounting screws, install the new assembly, and reconnect.
Ensure the replacement part matches your specific model number.
When to call a professional
If the door is stuck in the locked position and you cannot access the lock mechanism safely, call a technician to avoid damaging the oven.
