Samsung Dryer dC Error
What it means
On a Samsung dryer, dC (sometimes shown as DC) is a door-related error meaning the door is not closed or latched properly. Safety sensors won't let the dryer run until they confirm the door is securely shut, so the cycle stops and the code appears. It usually comes down to a door that won't stay closed, a misaligned or damaged latch, or lint/items caught around the seal — though a faulty door switch or sensor can also trigger it.
Common causes of the dC error
- The door wasn't pushed firmly enough to latch fully
- Lint or a small item caught in the door seal or strike, blocking proper closure
- A bent, loose, or broken door latch or strike
- Door misalignment that has gradually shifted with daily use
- A failed door switch or door sensor that doesn't register the closed door
How to fix the Samsung Dryer dC error
- 1Close the door firmly and re-runPush the door shut with a firm press until you hear or feel it latch, then start a cycle again. A door that's only slightly ajar is the most common cause of dC.
- 2Clean around the door seal and latchCheck the door gasket, latch, and strike for lint or a stray item (a sock, a sheet) blocking a clean seal. Wipe the area with a soft cloth and clear any debris so the door can close fully.
- 3Inspect the latch and strike for damageLook closely at the latch and the strike it catches on. If anything is visibly bent, loose, or broken, it should be repaired or replaced — a damaged latch can't tell the dryer the door is secure.
- 4Reset the dryerUnplug the dryer (or switch off its breaker) for at least one minute, then restore power and run a short empty test cycle. This clears a temporary glitch the control may be misreading as a door fault.
🧰 When to call a professional
If dC keeps returning after you've closed the door firmly, cleared the seal, checked the latch, and reset the dryer, the door switch, sensor, or control board may be at fault. If the latch or door itself is damaged, contact Samsung Support to request service rather than forcing the door. Unplug the dryer before any closer inspection of the latch or wiring.
Samsung dC error — FAQ
My door is closed but I still get dC — what now?
Open and re-close it with a firm push to be sure it latches, then check the seal and latch for lint or damage. If it still shows after a one-minute power reset, the door switch or sensor likely needs service.
Does dC mean my dryer is damaged?
Often not — it's most commonly a door that isn't fully latched or something caught in the seal. Only if it persists after cleaning, checking the latch, and resetting should you suspect a faulty switch, sensor, or control board.
How do I reset a Samsung dryer to clear dC?
Unplug the dryer or switch off its breaker for at least one minute, then restore power and run a brief empty cycle. This clears temporary errors; if dC comes right back, the cause is mechanical or a sensor fault.
