Problem: Inlet thermistor failure – temperature sensor reading out of range
How to Fix 001 Error
- UNPLUG THE DRYER. This code indicates the inlet thermistor has failed (open circuit or out of range).
- The inlet thermistor is located on the blower housing or heater assembly. Remove the front or rear panel to access it.
- Disconnect the wire harness from the thermistor. Use a multimeter set to Ohms (Ω) to test its resistance.
- At room temperature (~77°F/25°C), it should read approximately 10,000 ohms (10kΩ). An ‘open’ or infinite reading (often displayed as ‘OL’) confirms it’s bad.
- Unscrew the old thermistor, install the new one, reconnect the wiring, and reassemble the dryer.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
