Error Code Explained

What Does the Samsung dC Error Code Mean?

The dC error code on a Samsung dryer indicates the dryer door is open or the door switch is not reading correctly. Samsung dryers require a confirmed door-closed signal before starting or continuing a cycle. When the signal is absent or intermittent, dC is displayed and the cycle halts.

dC may appear even when the door is physically closed if the door switch, door latch, or wiring harness has failed.

Root Causes

Common Causes of the Samsung dC Error Code

1

Door Not Fully Latched

The door was not closed firmly enough for the latch to engage the strike.
2

Worn Door Latch or Strike

The plastic latch tab or door strike has worn or broken, preventing consistent contact with the switch.
3

Failed Door Switch

The microswitch behind the door frame has failed open, sending a constant "door open" signal to the PCB.
4

Loose Wiring to Door Switch

The harness connector to the door switch has loosened.

Step-by-Step Guide

How to Troubleshoot the dC Error Code

⚠️

Safety First: Always disconnect the Dryer from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Close door firmly

Press the door firmly until you feel the latch click fully engaged. Restart the cycle.
2

Inspect door latch

Examine the latch tab on the door and the strike on the frame. Replace if worn or cracked — plastic latch strikes are inexpensive and commonly the cause of dC on dryers over 5 years old.

FAQ

Frequently Asked Questions — Samsung dC

No — the door switch is a safety interlock. Running the dryer with the door open or unlatched is a fire and injury hazard. Replace the switch rather than bypassing it.
A worn latch may hold the door closed during loading but lose contact as the drum vibration increases. The door appears closed but the switch intermittently loses contact, triggering dC mid-cycle. Replace the door latch and strike.
