Squealing, squeaking, or rattling sounds during operation caused by a worn idler pulley bearing or wobbling pulley wheel losing smooth contact with the drive belt.
Dryer motor runs but drum does not rotate because a failed idler pulley can no longer maintain proper tension on the drive belt, causing the belt to slip or disengage.
If the drive belt has snapped due to a seized or damaged idler pulley, the dryer's belt-break safety switch prevents the motor from running at all.
A worn idler pulley intermittently loses belt tension, allowing the belt to slip off the drum mid-cycle, causing unexpected stops during drying.
A rough or wobbling pulley wheel creates excessive friction and uneven wear on the drive belt, causing premature belt failure even after fresh belt replacement.
💡 Pro Tip: Is Your Idler Pulley the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Loud squealing, squeaking, or rattling noise when the dryer starts or runs
⚠️ Drum fails to rotate or rotates unevenly despite the motor running
⚠️ Dryer stops unexpectedly mid-cycle (belt slips off worn pulley)
⚠️ Drive belt breaks repeatedly — a worn pulley wheel causes premature belt failure
🔍 Diagnosis tip: Remove the front or back panel, manually rotate the drum and watch the idler arm — if the pulley wobbles, drags, or the bearing is enlarged/rough, replace it immediately. While the dryer is apart, inspect the drive belt for glazing or fraying and consider replacing both together to save a second disassembly.
