How to Fix / Troubleshooting

Safety first: Unplug the dryer. Overheating can cause fires.

Step-by-step checks:

Check venting: Ensure the exhaust vent is clear and properly installed. Restricted airflow can cause overheating.
Test cycling thermostat: Remove and test the thermostat for proper opening temperature (requires heating and thermometer). Replace if stuck closed.
Inspect control relay: On electronic models, check if the heater relay contacts are welded closed (heater on when it should be off). Replace the control board if so.
Thermistor test: Measure thermistor resistance and compare to specs. Replace if readings are out of range.

When to call a technician: If overheating persists after basic repairs, stop using the dryer and call a professional.
