⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: HC2 Difficulty: Moderate
Problem: The dryer heater (on combo units) is overheating. This is usually caused by a blocked air duct or a bad fan preventing proper airflow over the heater.
How to Fix HC2 Error
- UNPLUG washer from electrical power.
- Remove lower front access panel to access tub assembly.
- Locate thermistor mounted near heater assembly on tub wall. Disconnect wiring harness.
- Measure resistance across thermistor terminals with multimeter. At room temperature, should read ~10kΩ.
- If resistance reads near zero ohms (shorted) or fluctuates wildly, replace thermistor.
- Remove mounting screw securing sensor. Gently pry thermistor from tub wall without damaging threads.
- Clean mounting surface on tub with isopropyl alcohol. Apply thermal conductive paste to new sensor base.
- Install new thermistor using OEM part DC34-00040A. Secure with mounting screw tightened to 8 in-lbs.
- Reconnect harness. Inspect wiring for melted insulation near heater; repair if damaged.
- Reassemble panel. Run warm water cycle to verify temperature display updates smoothly.
