Understanding the Problem
When a dryer's drive belt breaks the drum will not turn, so clothes won't tumble and drying stops even though the heater may still run. The belt wraps around the drum and the motor pulley; when it snaps or slips off, the motor may run but the drum remains stationary or produces a squeal. You may hear the motor running without tumbling, feel no resistance when attempting to spin the drum by hand, or notice a burning rubber smell if the belt shredded. A broken belt is one of the most common and straightforward dryer repairs. However, belts usually fail because of worn drum rollers, a seized idler pulley, or misalignment — so it's best to inspect and often replace the belt plus the related components at the same time. Replacing only the belt without addressing the underlying cause often leads to another failure shortly afterward.
Common Symptoms
Drum won't tumble but motor runs; loud squealing or scraping; burning rubber smell; drum spins freely by hand or belt is visibly snapped/off.
Common Causes
- Normal wear and age of the drive belt leading to cracking or snapping
- Seized or worn idler pulley or drum rollers causing excess friction and belt failure
- Misalignment or foreign objects caught between drum and cabinet that abrade the belt

Helpful Repair Tip
Open the dryer front or rear panel and try to rotate the drum by hand. If the drum turns freely with no resistance while the motor runs, the belt is likely broken or off the drum. Look for missing belt segments, glazing, or shredding.
Frequently Asked Questions
Can I run the dryer with a broken belt?
No. Running a dryer with a broken or slipped belt can damage the motor or other components because the motor may run without proper load and bearings may overheat. Replace the belt (and inspect related parts) before using the dryer again.
How much does it cost to replace a dryer belt?
Parts alone typically cost $15–$60 depending on brand and whether you also replace rollers or the idler. If you hire a technician, total cost (parts + labor) is commonly $100–$250. Replacing the belt yourself is usually a 30–90 minute job with basic tools and a service manual or model-specific guide.
