Whirlpool Washer - F37 Error Code

Temperature sensor failure detected.

Meaning

Temperature sensor failure detected.

The F37 error indicates that the washer’s temperature sensor (NTC thermistor) is reading values outside the expected range. On Whirlpool Cabrio and HE top‑load washers and Duet front-load washers, the temperature sensor monitors incoming water temperature to ensure proper cycle performance. If the sensor is open, shorted, or providing erratic readings, the washer cannot safely regulate temperature and triggers F37. This error is common when the sensor wiring becomes loose, corroded, or damaged by moisture.

Symptoms

  • Washer stops early in the cycle
  • Incorrect water temperature
  • F37 appears shortly after filling
  • Washer refuses to start certain cycles

Causes

  • Faulty NTC temperature sensor
  • Loose or corroded wiring harness
  • Moisture intrusion in the sensor area
  • Open or shorted sensor circuit
🔧

Step-by-Step Fixes

  • Unplug the washer and access the temperature sensor.
  • Inspect the wiring harness for corrosion or loose connections.
  • Test the sensor with a multimeter (typically 10–12kΩ at room temperature).
  • Replace the sensor if readings are out of range.
  • Inspect the control board if the sensor tests good.
⚠️

Safety Notes

  • Disconnect power before accessing internal components.
  • Avoid touching the heating element immediately after use.

Model-Specific Notes

On early Cabrio models, the temperature sensor is mounted near the inlet valve assembly, making it vulnerable to moisture from leaks or condensation. On Duet models, the temperature sensor is mounted directly to the heater assembly, making it sensitive to mineral buildup and moisture.
