Dryer Idler Pulley Replacement – Troubleshooting and Repair Guide
The idler pulley maintains tension on the dryer drive belt. Without the pulley, the belt would slip off the motor pulley and the drum would stop spinning.
If the idler pulley bearing wears out, it may produce squealing noises or allow the belt to slip.
