Dryer emits a loud squeal, screech, or grinding sound during operation or at startup — caused by a worn, dry, or seized idler pulley bearing.
Motor runs but the drum does not rotate because the failed idler pulley can no longer maintain proper tension on the drive belt.
Drum spins but stops intermittently or produces a repetitive clunking noise as the slipping belt skips over a damaged or flat-spotted pulley wheel.
A completely seized idler pulley causes belt binding against the motor shaft, preventing the motor from turning and the dryer from starting at all.
💡 Pro Tip: Is Your Idler Pulley the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Loud squealing, screeching, or grinding noise during or at dryer startup
⚠️ Drum fails to rotate even though the motor is running
⚠️ Dryer starts but drum spins intermittently or with a clunking sound
⚠️ Visible cracks, flat spots, or seized bearing on the old pulley wheel
🔍 Diagnostic Tip: Reach into the lower service panel, depress the idler arm, and spin the pulley wheel by hand. It should rotate freely and silently. Any roughness, wobble, or resistance means it's time to replace. While the dryer is open, inspect the drive belt for cracks or fraying — replacing both at the same time saves a second teardown.
