Possible Causes
Failed blower motor (on some models with separate blower), blocked blower housing, loose blower wheel, defective airflow sensor (if equipped)
How to Fix / Troubleshooting
Safety First: Disconnect power and gas before opening the cabinet.
Steps:
- Check for airflow: With the vent disconnected, briefly run the dryer (if it will run) and feel for strong airflow at the outlet. Weak or no airflow indicates a blower issue.
- Inspect blower housing: Remove the front or rear panel to access the blower housing. Clear any lint clogs, socks, or debris.
- Check blower wheel: Ensure the blower wheel is not cracked and is firmly attached to the motor shaft. Replace if loose or damaged.
- Blower motor (if separate): On models with a dedicated blower motor, test for proper voltage at the motor when running. Replace the motor if it hums but does not turn or tests open.
