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 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.
Parts Involved
How to Fix
- 1
1. Check the PCB and thermistor
- 2
2. Check exhaust vent system for restrictions or blockages
- 3
3. Measure thermistor resistance: should be 10K Ohm at 25 deg C (77 deg F)
- 4
4. Check thermostat 1 resistance: should be < 1 Ohm (infinity means replace)
- 5
5. Check thermostat 2 resistance: should be < 1 Ohm (infinity means replace)
- 6
6. Check thermostat 3 resistance: should be < 1 Ohm (infinity means replace)
- 7
7. Check heater resistance: [SINGLE] 10 Ohm (PIN 1-3); [DUAL] 13 Ohm (PIN 2-3) and 34 Ohm (PIN 1-2)
- 8
8. If resistance is infinity on any heating component, replace that component
