The drum does not rotate even though the motor runs — a seized or broken idler pulley allows the drive belt to slip off or lose tension entirely.
A worn or dry pulley bearing creates a high-pitched squealing or screeching sound throughout the drying cycle.
A pulley that is seizing up generates excess friction against the belt, producing heat and a burning rubber odor.
A worn or stuck idler pulley cannot smoothly guide the drive belt, causing the drum to run unevenly and the cabinet to vibrate.
💡 Pro Tip: How to Diagnose a Failing Idler Pulley
Your part is likely the culprit if you notice any of the following:
⚠️ Loud squeaking or screeching noise during dryer operation — classic sign of worn pulley bearing
⚠️ Drum does not tumble even though the motor is running — belt has slipped off a seized pulley
⚠️ Burning smell or excessive heat near the motor area — pulley seizing up and creating friction
⚠️ Visible cracks, flat spots, or wobble on the pulley wheel itself — replace immediately before belt damage occurs
🔍 Diagnostic tip: With the dryer unplugged, remove the front panel and spin the idler pulley by hand. If it drags, wobbles, or grinds instead of spinning freely, it needs replacement. While you're in there, inspect the drive belt for cracks — replacing both at the same time is best practice and saves a second disassembly.
