Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Persistent squealing or squeaking from the belt-drive area.
• Pulley wheel does not spin freely or appears seized when inspected with power disconnected.
• Drive belt slips, loses tension, or repeatedly comes off the pulley.
• Drum fails to rotate or rotates intermittently when the idler assembly cannot maintain belt tension.

Check Before Replacing

• Disconnect electrical power before inspection; shut off the gas supply on gas dryer models.
• With the dryer de-energized and access provided according to the appliance service documentation, visually inspect the idler wheel and arm for wear, cracking, damage, or misalignment.
• Check whether the idler wheel rotates freely by hand without forcing it.
• Inspect the belt path to confirm the belt remains seated and is routed around the motor and idler pulley as shown in the appliance documentation.
• Do not operate the dryer with panels removed or while hands are near the belt, pulley, or motor.
