Kenmore Washer Dryer: thermistor error

Professional Repair Guide

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.

Urgency: Medium

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

Moderate 20–40 minutes
Tools Needed: multimeter, screwdriver set
  1. Unplug the washer‑dryer and ensure power is off.
  2. Access the thermistor location.
  3. Disconnect the thermistor harness and set your multimeter to resistance (ohms).
  4. Measure resistance at room temperature; compare to expected range.
  5. Gently heat the thermistor (e.g., with a hair dryer) and confirm resistance decreases.
  6. If resistance is open, shorted, or doesn’t change with temperature, thermistor is faulty.
⚠️ Safety First: Always disconnect power before accessing internal components

Inspect and Secure Thermistor Wiring/Connector

Easy 10–15 minutes
Tools Needed: flashlight
  1. Unplug the unit and open access panel.
  2. Visually inspect thermistor wiring and connector for corrosion, looseness, damage.
  3. Clean any corrosion and ensure tight fit at the connector.
  4. Reassemble panels and test dryer operation.
⚠️ Safety First: Ensure power disconnected before inspecting
