Understanding the Problem
When a dryer belt breaks the drum will not turn even though the motor may run. The belt wraps around the drum and connects it to the motor pulley and idler; when it snaps the drum loses drive and clothes won't tumble. Broken belts usually fail from age, rubbing against worn rollers or guides, or sudden strain from an overloaded drum. Replacing the belt is usually a straightforward repair, but you should inspect the idler pulley, drum rollers, drum glides/slides and the motor shaft for wear. If the belt rode on a seized roller or a sharp edge, the new belt can wear out quickly unless those worn components are replaced at the same time.
Common Symptoms
Drum won’t turn but motor sounds like it’s running; loud squeal or grinding when trying to start; burning rubber smell; visible snapped or loose belt when the panel is removed.
Common Causes
- Normal wear and age: belt material cracks, frays, or stretches until it breaks
- Worn or seized idler pulley or drum rollers that create extra friction and quickly wear the belt
- Overloading or a stuck item in the drum that suddenly stresses the belt

Helpful Repair Tip
Open the dryer cabinet (or remove the front panel) and manually try to turn the drum. If the drum spins freely by hand and you find a snapped or loose belt, the belt is the likely culprit. Also inspect rollers and the idler for roughness or play before installing a new belt.
Frequently Asked Questions
Can I run the dryer with a broken belt?
No. The motor may run but the drum won't turn, and running the motor under no-load or with a damaged belt can overheat or damage the motor or idler. Turn the dryer off and inspect/repair before further use.
How long does it take to replace a dryer belt and how difficult is it?
A belt replacement typically takes 30–90 minutes depending on model and your experience. Difficulty is moderate: you need basic tools (screwdrivers, possibly a socket set), to access the drum and route the new belt around the drum and pulleys, and to check related parts (idler, rollers, glides). Follow a model-specific guide or service manual for panel removal and belt routing.
