A worn or seized idler pulley bearing causes loud squeaking, grinding, or rumbling sounds during the drying cycle. Replacing the assembly eliminates the noise source.
If the idler pulley fails to maintain tension on the drive belt, the belt slips off or goes slack and the drum stops rotating even while the motor runs.
A worn pulley that wobbles on its shaft causes unbalanced belt movement, leading to noticeable vibration and shaking throughout the dryer cabinet during operation.
A completely seized or broken idler pulley prevents the belt from engaging the drum, causing the dryer to run but fail to tumble clothes from the very start of the cycle.
💡 Pro Tip: How to Tell If Your Idler Pulley Is Failing
Your part is likely the culprit if you notice any of the following:
⚠️ Loud squeaking, grinding, or rumbling noise during the drying cycle
⚠️ Dryer drum not spinning or tumbling even though motor runs
⚠️ Excessive vibration or shaking throughout the drying cycle
⚠️ Visible wear, wobble, or damage on the pulley wheel or bracket arm
🔍 Diagnostic tip: Manually spin the idler pulley wheel with your finger. If it doesn't rotate freely, feels rough, or wobbles side-to-side, replace the entire assembly. Also inspect the drive belt for glazing or cracking — it's best practice to replace both at the same time while the dryer is disassembled.
