Kenmore Washer Dryer: thermistor error
What is this symptom?
If your Kenmore Washer Dryer is displaying a thermistor error code like F1, F24, or F25, you may face issues such as no heating or inconsistent temperatures. This error indicates a fault in the thermistor, which is crucial for temperature regulation. Addressing this promptly can prevent further appliance malfunction.
Important Tips for Kenmore Models
- Kenmore dryers report specific thermistor error codes like F1, F24, F25 indicating thermistor open/short conditions
Possible Causes
Faulty thermistor (temperature sensor)
How to Identify: Error codes like F1, F24, F25 on Kenmore dryer; no/incorrect resistance reading at room temperature when tested with a multimeter; resistance not changing with temperature
Part: Thermistor (inlet or exhaust temperature sensor)
Wiring issue to thermistor (open/short/corroded connector)
How to Identify: Error code still present after thermistor testing; visual inspection shows loose, corroded, or damaged wiring/connector to the thermistor
Part: Thermistor wiring harness/connectors
Control board temperature sensing circuit fault
How to Identify: Thermistor tests good (resistance within spec and changing with heat, but error persists; other board errors present
Part: Main control board temperature circuit
DIY Solutions
Test Thermistor with Multimeter
- Unplug the washer‑dryer and ensure power is off.
- Access the thermistor location.
- Disconnect the thermistor harness and set your multimeter to resistance (ohms).
- Measure resistance at room temperature; compare to expected range.
- Gently heat the thermistor (e.g., with a hair dryer) and confirm resistance decreases.
- If resistance is open, shorted, or doesn’t change with temperature, thermistor is faulty.
Inspect and Secure Thermistor Wiring/Connector
- Unplug the unit and open access panel.
- Visually inspect thermistor wiring and connector for corrosion, looseness, damage.
- Clean any corrosion and ensure tight fit at the connector.
- Reassemble panels and test dryer operation.
