How to Fix / Troubleshooting

Safety first: Turn off and unplug the dryer immediately. Allow it to cool completely before inspection.

Airflow and fan:

  • Clean all filters and the condenser thoroughly.
  • Check the fan wheel and motor for lint build-up and ensure it spins freely and runs during a cycle.

Thermostats:

  • Access the heater housing and test the cycling thermostat and high-limit thermostat for correct operation with a multimeter.
  • Replace any thermostat that is shorted or does not open at the specified temperature (service data required for exact values).

After repair: Run a short test cycle and monitor temperature. If overheating persists, stop using the dryer and contact a professional.
