Motor runs but drum stays stationary — broken or snapped drive belt is the most common cause.
Loud thumping, squealing, or slapping sounds during the cycle caused by a worn, stretched, or fraying belt.
A slipping or partially broken belt creates friction against the drum or cabinet, producing a distinct burnt rubber odor.
Reduced drum rotation from a weakened belt causes inefficient tumbling and leaves laundry damp after a full cycle.
Some dryer models use a belt-switch safety mechanism — a broken belt triggers the switch and prevents the dryer from starting at all.
💡 Pro Tip: Is Your Dryer Belt the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer drum does not rotate even though the motor is running and you can hear it humming
⚠️ Loud thumping, squealing, or unusual rattling noise during the drying cycle
⚠️ Burning rubber smell coming from the dryer cabinet during or after operation
⚠️ Clothes remain damp after a full cycle due to reduced or no drum tumbling
Quick diagnosis: Open the dryer door, reach in and try to spin the drum by hand. If it spins freely with almost no resistance and the motor still runs, the belt is almost certainly broken. You can also visually inspect by removing the front panel — a snapped or visibly cracked belt confirms replacement is needed. Always unplug the dryer before any inspection or repair.
