Dryer ⚠ Safety Risk

Samsung HC — High Heat Error

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.
