Samsung Dryer Error Code dC — Door Open During Cycle
What this means
The dC error code indicates the dryer door was opened mid-cycle, or the door switch lost contact during operation. This is often caused by accidentally bumping the door open, a weak door catch, or vibration loosening the latch. If the door was not physically opened, the door switch or latch may be failing.
Step-by-step fix
3 stepsClose the door and restart
Make sure the dryer door is fully closed and latched. Press Start/Pause to resume the cycle. If the dryer resumes without error, the door was simply bumped open.
If the dryer is on an uneven surface, it may vibrate enough to unlatch the door. Level the dryer.
Check the door latch and catch
Inspect the door catch on the door itself and the latch receiver on the dryer frame. If either is worn, cracked, or doesn't hold securely, replace it.
The door catch is a common wear item and is inexpensive to replace.
Test the door switch
If the door appears closed but the error keeps triggering, test the door switch with a multimeter as described in the dF error code fix.
A door switch that works intermittently can cause this error during the vibration of a cycle.
When to call a professional
If the door hardware and switch are in good condition but the error persists during every cycle, there may be a wiring or control board issue that requires professional diagnosis.
