HC ⚠ Safety Risk Samsung Dryer HC — High Heat Error
The dryer shuts down mid-cycle and there is a hot, scorched smell at the door.
What does Samsung HC mean?
The dryer's thermistor or high-limit thermostat detected a temperature above the safe operating threshold. The dryer shuts off to prevent damage and fire risk.
What causes Samsung HC?
- Blocked exhaust duct (most common — see d80/d90 for duct cleaning steps)
- Failed thermistor giving a false high-temp reading
- Heating element shorted to ground (electric models)
- Gas valve failing to close properly (gas models — fire risk)
How to fix Samsung HC yourself
- 1 Check and clean the lint filter and exhaust duct (see d80 steps above).
- 2 After cleaning, let the dryer cool for 30 minutes before restarting.
- 3 If HC returns immediately on a clean duct, do not continue using the dryer.
