Samsung Dryer Error Code dC — What It Means & How to Fix It

What Does This Error Mean?

The dC error means the door on your Samsung dryer is not fully closed. The dryer detected the door is open or not latched properly. This is a safety feature — the dryer won't run unless the door is securely shut.

Common Causes

The dryer door wasn't pushed closed firmly enough
Clothing or a small item is caught in the door seal
The door latch or strike is worn or misaligned
The door switch sensor is faulty
The door hinge is loose or bent

How to Fix It

Open the dryer door and check for any clothing caught in the seal.

Small items like socks often get wedged between the door and the rubber gasket.
Close the door firmly until you hear it click shut.

Push on the door with a little extra force. Some Samsung dryers need a solid push.
Inspect the door latch and strike for damage.

The latch is on the door itself. The strike is the slot on the dryer body. Make sure neither is cracked or bent.
Clean the door latch area with a damp cloth.

Lint buildup around the latch can prevent it from engaging properly.
If the error continues, the door switch sensor may need replacement.

This is an inexpensive part. A technician can swap it quickly.

When to Call a Professional

If the door closes firmly but the error persists, the door switch may be faulty. This is a relatively inexpensive repair. Expect costs of $75–$175 including parts and labor. A technician can replace the switch in about 30 minutes.

Frequently Asked Questions

Why won't my Samsung dryer start and shows dC?

The dryer thinks the door is open. It won't start for safety reasons. Try opening and firmly closing the door again. Check for items stuck in the door seal.

Is the dC error serious on a Samsung dryer?

No, it's usually a minor issue. Most of the time, just closing the door properly fixes it. If it keeps happening, the door switch may need replacing. That's a quick, inexpensive repair.

Can lint cause the dC door error?

Yes, lint buildup around the door latch area can interfere. The latch may not engage fully if there's debris in the way. Wipe the latch and strike area with a damp cloth. This simple cleaning often solves the problem.
