Dryer runs but emits a loud high-pitched squeal or screech throughout the cycle caused by the worn idler pulley wheel binding on its shaft.
Rhythmic thumping or grinding during operation indicating the pulley wheel has flat spots, cracks, or the bearing has seized.
Dryer motor runs but drum doesn't turn because a fully seized idler pulley has caused the drive belt to slip off or break.
Drive belt repeatedly derails from the drum or motor pulley because the idler arm can no longer maintain proper consistent belt tension.
Friction from a stuck idler pulley wheel dragging against the spinning belt generates heat and produces a burning smell from inside the cabinet.
💡 Pro Tip: Is Your Idler Pulley Failing?
Your part is likely the culprit if you notice any of the following:
⚠️ Loud squealing, screeching, or grinding noise during the entire dry cycle
⚠️ Dryer drum turns slowly, stops mid-cycle, or won't spin at all
⚠️ Drive belt keeps slipping off or breaks prematurely
⚠️ Burning rubber smell coming from the dryer cabinet
🔍 Diagnosis Tip: Open the dryer cabinet and manually spin the idler pulley wheel with your finger. It should spin freely and smoothly with no wobble, grinding, or stiffness. If it feels rough, catches, or wobbles side-to-side, replace it immediately — a seized pulley will burn through a new belt within hours.
