How to Fix / Troubleshooting
Safety first: Unplug the dryer before testing switches or accessing internal components.
Step-by-step checks:
- Door switch: Ensure the door is fully closed. Test the door switch for continuity when closed; replace if faulty.
- Thermal fuse: Test the thermal fuse on the blower housing. If open, replace and correct any airflow issues.
- Start switch: Access the Start button or switch and test for continuity when pressed. Replace if open.
- Motor and relay: If switches and fuse are good, the motor or its relay on the control board may be defective and require further diagnosis or replacement.
When to call a technician: If you suspect motor or control board failure, professional diagnosis is recommended.
