Error Code hE
Your dryer isn't heating properly or is overheating
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: hE
What This Means
Restricted vent system causing excessive heat buildup; Thermistor resistance out of range; Heater malfunction or open element; Thermostat failure (tripped or open)
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 exhaust vent system for restrictions or blockages
- 2
2. Measure cycling thermistor 1 resistance: should be 10KOhm at 25C (77F)
- 3
3. Check thermostat 1 resistance: should be < 1Ohm (infinity means replace) — 85C 25A thermal cut-off
- 4
4. Check thermostat 2 resistance: should be < 1Ohm (infinity means replace)
- 5
5. Check thermostat 3 resistance: should be < 1Ohm (infinity means replace)
- 6
6. Check heater resistance: 13Ohm between PIN 2-3, 34Ohm between PIN 1-2 (electric model)
- 7
7. If resistance is infinity on heater, replace heater assembly
- 8
8. For gas model: check radiant sensor, igniter, gas valve, and hi-limit thermostat
