Understanding the Problem
When a dryer belt breaks the drum will not rotate even though the motor may run. Most dryers use a flexible rubber or fabric-reinforced belt wrapped around the drum, idler pulley, and motor shaft; if the belt snaps or loses integrity the drum will spin freely by hand but won’t be driven. You may hear the motor running, notice a loud thumping when the belt fails, or smell a burnt rubber odor at the time of failure. A broken belt can be caused by age and wear, rubbing against a damaged drum edge or pulley, or the idler pulley/motor bearing seizing and putting extra stress on the belt. Replacing the belt is typically straightforward on many common models, but inspect the idler pulley, drum rollers, and motor shaft for damage — replacing only the belt while a damaged pulley remains will often cause a second failure soon after.
Common Symptoms
Drum doesn't turn but motor runs; loud thump or snap at failure; burning rubber smell; clothes remain wet; occasional squeal or rubbing noise before failure.
Common Causes
- Normal wear and degradation of the drum belt over time
- Seized or worn idler pulley or drum rollers causing extra belt stress
- Foreign objects, sharp drum edge, or misalignment cutting or abrading the belt

Helpful Repair Tip
With the dryer off and unplugged, try turning the drum by hand. If the drum spins freely and the motor runs when you start the dryer, the belt is likely broken. Also look inside the cabinet for an obvious snapped belt piece.
Frequently Asked Questions
Can I replace a dryer belt myself?
Yes — replacing a dryer belt is a common DIY repair. Always unplug the dryer (or shut off its breaker) before starting. Basic steps: remove the lint filter and front or rear panel per your model, locate and remove the broken belt, loop the new belt around the drum and motor pulley following the factory routing, re-tension with the idler pulley, and reassemble. Keep the model number handy so you buy the correct belt and follow a model-specific guide or video.
How much does it cost to fix a broken dryer belt?
Parts alone are inexpensive — typically $10–$40 for a replacement belt and $10–$40 for an idler or roller if needed. If you hire a technician, labor adds $80–$200 depending on region and access. If additional components like the motor or rollers are damaged, parts and labor will increase accordingly.
