What it means

Firmly push the door shut until you hear a click, then press Start again.

Affected Models

Samsung Electric Dryer
Samsung Gas Dryer
Samsung DV Series
Samsung Smart Dryer

Common Causes

Door not pushed fully closed
Laundry item caught in the door seal
Worn or broken door latch
Faulty door switch not detecting closure
Damaged door hinge causing misalignment

How to Fix It

Push the door firmly shut.

You should hear and feel a definite click.
If the door feels loose or spongy, the latch or strike is worn.
Check for laundry caught in the door seal.

Open the door and inspect the rubber gasket around the drum opening.
A sock or small item trapped in the seal prevents the door from latching fully.
Inspect the door latch and strike plate.

Look at the plastic latch on the door edge and the metal strike on the dryer body.
A cracked latch or bent strike will prevent the door from locking — both parts are inexpensive to replace.
Test the door switch.

Unplug the dryer and locate the door switch (behind the front panel near the door opening).
Use a multimeter to test for continuity — the switch should close when the door is pressed and open when released.
Replace if faulty.

When to Call a Professional

If the door closes firmly with a click but DC still shows, the door switch has failed internally.
An appliance technician can replace it quickly and affordably.

Frequently Asked Questions

Samsung dryer shows DC but the door is closed — what else could cause this?

If the door appears fully closed but DC persists, the door switch is detecting it as open even when it is not. Unplug the dryer and test or replace the door switch behind the front panel.

Is DC the same as dC or d C on a Samsung dryer?

Yes — Samsung displays the same door error as DC, dC, or d C depending on the model and display type. They all mean the door is not sensed as fully closed.
