Error Code HC
Your dryer isn't heating properly or is overheating
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: HC
What This Means
Restricted vent system causing excessive heat buildup; Thermistor resistance out of range; Heater malfunction; Thermostat failure; PCB fault
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.
Parts Involved
How to Fix
- 1
1. Check the PCB and thermistor connections
- 2
2. Measure thermistor 1 resistance: should be 10KOhm at 25 deg C (77 deg F)
- 3
3. Measure thermistor 2 resistance: should be 238.231KOhm at 25 deg C (77 deg F)
- 4
4. Check exhaust vent system for restrictions or blockages
- 5
5. Check thermostat resistance: should be < 1 Ohm (infinity means replace)
- 6
6. Check heater resistance: SINGLE heater 10 Ohm (PIN 1-3), DUAL heater 13 Ohm (PIN 2-3) and 34 Ohm (PIN 1-2)
- 7
7. If resistance is infinity on heater, replace heater assembly
