Blocked lint in air ducts, Failed or tripped thermal cut-out, Faulty dryer fan, Restricted condenser airflow

How to Fix / Troubleshooting

Safety first: Unplug the appliance and allow it to cool fully before working on the dryer system.

  • Step 1 – Clean lint and condenser: Remove accessible lint filters and clean thoroughly. If the condenser is user-accessible, remove and rinse it under running water until clear.
  • Step 2 – Inspect air ducts: Remove panels to access internal ducts. Vacuum out lint and debris to restore airflow.
  • Step 3 – Check thermal cut-outs: Locate thermostats on the dryer heater housing. Test for continuity. Replace any that are open circuit and not resettable.
  • Step 4 – Verify fan operation: Ensure the dryer fan runs during drying. If not, test and replace the fan motor as needed.
