Frequently Asked Questions

Why does my Samsung dryer show DC when the door is closed?
The door latch hook has likely worn smooth and is no longer fully engaging the strike. The door feels closed but the switch is not making contact. Replace the door latch assembly DC64-00519B.
Is DC the same as DE on Samsung dryers?
Yes. DC and DE both indicate a door sensor fault. The code displayed depends on the model and firmware version. The diagnosis and repair procedure are identical.
Can I run my dryer with a DC error code?
No. The dryer will not start or will stop if the DC code is active because the control board requires confirmation that the door is sealed before heating. Running it with a forced override risks heat escaping from the unsealed door.
