Possible Causes

Clogged lint filter or vent, Failing motor overheating, Weak cycling thermostat, Blocked condenser airflow

How to Fix / Troubleshooting

Safety first: Unplug the dryer and allow it to cool fully before inspection.

  • Clean airflow paths: Thoroughly clean the lint filter, exhaust duct, and condenser (if fitted) to ensure proper airflow.
  • Check motor ventilation: Inspect the motor area for lint buildup that can trap heat. Vacuum carefully.
  • Test thermostats: Check the cycling thermostat and high-limit thermostat for proper operation. Replace if they trip prematurely.
  • Motor condition: If the dryer stops and the motor is extremely hot to the touch, the drive motor may be failing and drawing excessive current. Replacement is recommended.
