Samsung Oven C-d1 Error Code — What It Means

C-d1 shows when the oven door lock will not move correctly or fails to report the right state to the control board. It often appears during or right after a self clean cycle when the motorized latch is in play.

The board needs a clear locked or unlocked signal from the latch switch. When that signal does not match what the board commanded, it posts C-d1 and may leave the door locked.

Common Causes

Failed lock motor The small motor that drives the latch has burnt out and no longer moves the bolt.
Jammed latch Food debris or charred residue around the latch blocks it from reaching the locked or unlocked stop.
Bad latch switch The microswitch that confirms latch position has failed and never reports the correct state.
Loose lock wiring A disconnected or chafed harness between the lock and the board breaks the position signal.
Control board fault Less often the board misreads a good lock and holds the error.

Step-by-Step Fix

Cut power at the breaker for a few minutes, then restore it to let the lock motor reset its position.
Check that the door is pushed fully flush and closed.
Inspect the latch area for food debris or burnt residue and clear anything blocking travel.
Pull the range and remove the top or back panel to reach the door lock assembly.
Check the wire harness between the lock and the control board and reseat any loose connector.
Test the lock motor and latch switch for continuity, then replace the lock assembly if either fails.
Restore power and run a lock cycle to confirm the latch moves and clears the code.

When to Call a Pro

If the door stays locked and a power cycle does not free it, do not pry it open. Forcing a self clean latch can break the mechanism. A tech can release the latch safely and swap the lock assembly without damaging the door.
