Possible Causes
Failed drying fan motor, Blocked fan duct, Wiring fault to fan, Control board fan driver failure
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal panels.
- Listen for fan: During the drying phase, listen for the drying fan. If it is silent, it may have failed.
- Check vents: Inspect the interior and exterior vents for blockages or lint buildup. Clean as needed.
- Inspect fan wiring: Access the fan assembly (often in the door or side panel) and check wiring connections.
If the fan motor is seized or open-circuit, replace the drying fan assembly. If the fan is good but not powered, the control board may be at fault.
