Common Symptoms
- Drying cycle takes too long
- Drying cycle ends too soon
- Dryer displays a temperature-related fault code
Check Before Replacing
- Disconnect power before testing or servicing.
- Measure thermistor resistance; Whirlpool Parts lists approximately 11.9 kΩ at 70°F (21°C).
- A defective thermistor may cause altered drying time or a fault code, but it is not the cause of a dryer not heating.
Pro Tip
Verify the model number before ordering; the thermistor is model-specific even when the part number is used across multiple dryer brands.
