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 failure or resistance out of range; Heater malfunction (open or shorted element); Thermostat failure; PCB malfunction in temperature monitoring circuit; Compressor terminal wiring desorption (pin connection issue)
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. Measure thermistor resistance: should be 10K ohm at 25 deg C (77 deg F)
- 3
3. Check thermostat 1 resistance: should be < 1 ohm (infinity means replace)
- 4
4. Check thermostat 2 resistance: should be < 1 ohm (infinity means replace)
- 5
5. Check thermostat 3 resistance: should be < 1 ohm (infinity means replace)
- 6
6. Check heater: SINGLE — 10 ohm (PIN 1-3); DUAL — 13 ohm (PIN 2-3) and 34 ohm (PIN 1-2)
- 7
7. If any resistance is infinite, replace the corresponding component
- 8
8. For gas models, check igniter resistance: 40-400 ohm; check gas valve coil resistances
- 9
9. Operate time dry for 20 minutes after service and verify HC error does not recur
