✅ Cross Reference Information

Current Part NumberWP8557403

Common Symptoms

  • No heat when the high-limit thermostat is open or failed.
  • Overheating when the high-limit thermostat does not interrupt the heating circuit correctly.
  • Temperature-sensing or heating-control faults when the inlet thermistor is out of specification.

Check Before Replacing

  • Disconnect power before testing.
  • Check the high-limit thermostat for continuity with the component at room temperature; an open reading may indicate a failed thermostat, subject to the model's technical documentation.
  • Measure the inlet thermistor resistance at room temperature; Whirlpool documentation for this part specifies approximately 50–60 kΩ.
  • Verify the dryer model's parts list before replacement because this assembly is model-specific.

Pro Tip

Test the thermistor and thermostat separately where possible; a no-heat or overheating condition can also result from restricted airflow or another heating-system component.
