Possible Causes

Blocked airflow causing high temperature, Weak motor overheating and tripping internal overload, Failing cycling thermostat, Excessive load size

How to Fix / Troubleshooting

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

Intermittent shutdowns with a hot cabinet often indicate overheating protection is activating.

  • Reduce load size: Overloading can cause poor airflow and motor strain. Try smaller loads and see if the problem persists.
  • Clean airflow system: Thoroughly clean the lint filter, internal ducts, condenser (if applicable), and external vent. Remove all lint and obstructions.
  • Check motor ventilation: Access the motor area and remove lint buildup around the motor and fan. Ensure the motor cooling vents are clear.
  • Test cycling thermostat: If the thermostat is not opening at the correct temperature, the dryer may run too hot. Replace if out of specification.
  • Motor overload: If the motor stops and restarts only after cooling, the internal overload may be tripping due to a weak motor. Replacement of the drive motor may be required.
