Your dryer isn't heating properly or is overheating
Critical

Also displayed as: HC
What This Means
Clogged lint filter restricting airflow; Restricted exhaust vent system causing heat buildup; Thermistor malfunction reading incorrect temperature; Thermostat failure not cycling heater properly; Heater element malfunction
What actually causes this:
Most often caused by a clogged exhaust vent that traps hot air inside the dryer, or the heating element has burned out.
First Thing to Check
Check your exhaust vent — disconnect it from the back of the dryer and look for lint buildup inside.

- 2
2. Inspect exhaust vent system for restrictions, lint buildup, or blockages
- 3
3. Check outside exhaust hood damper — ensure it opens and closes freely
- 4
4. Measure thermistor resistance: should be 10K ohms at 25 degrees C (77 degrees F)
- 5
5. Check thermostat resistance: should be less than 1 ohm (infinity means replace)
- 6
6. Check heater resistance: DUAL heater — 13 ohms (PIN 2-3), 34 ohms (PIN 1-2)
- 7
7. If all components test normal, enter line test mode (HC4) for further diagnosis
