Understanding the Problem
The dryer drum belt (also called the drive or drum belt) wraps around the drum and connects to the motor and idler pulley. When the belt snaps or slips off, the motor may run but the drum won’t turn, or the drum may turn intermittently with a loud thumping or squealing noise. Because the belt runs under tension around pulleys, failure can create additional damage to the idler pulley, motor shaft, or drum glides if the dryer is run after the belt fails. A broken belt is one of the most common and straightforward dryer repairs. The repair typically involves unplugging the dryer, removing the front (or top/back, depending on model) to access the drum, replacing the belt and any damaged idler pulley or worn drum glides, and reassembling. Always verify the exact replacement part for your model number — belt dimensions and pulley types differ by manufacturer and model year.
Common Symptoms
Dryer motor runs but drum doesn't tumble; loud thump or screech when starting; burning rubber smell; drum spins freely when the dryer is off (belt missing or snapped).
Common Causes
- Belt wear from age and heat — cracks, fraying, or snapped strands
- Seized or worn idler pulley or drum roller causing excessive belt wear or belt jump-off
- Obstruction or sudden jam (clothing caught) causing belt to snap or slip

Helpful Repair Tip
Confirm a broken belt by opening the dryer and visually inspecting the belt around the drum. If the motor runs but the drum does not turn (or drum spins freely by hand when the machine is off), the belt is likely broken or slipped off.
Frequently Asked Questions
Can I run the dryer if the belt is broken?
No. Running the dryer with a broken belt can damage the motor or other components (idler pulley, drum glides). If the drum isn't turning, unplug the dryer and inspect the belt before using again.
How much does it cost to replace a dryer belt?
Parts for a belt-only replacement are typically inexpensive: $15–$50 for a correct OEM or compatible belt. If you also replace the idler pulley or rollers, parts can total $30–$120. Labor (if you hire a pro) is usually 1–2 hours, so expect service costs in the $100–$250 range depending on rates and whether additional parts (motor, rollers) are needed.
