Understanding the Problem
When a dryer belt breaks the drum will not rotate even though the motor and heating elements may still run. The belt wraps around the drum and connects it to the motor pulley (and usually an idler or tensioner). Over time the belt can wear thin, crack, slip off, or snap entirely. A broken belt results in no tumbling, poor drying, and often unusual noises when the motor runs without the drum turning. A broken belt is a common, usually inexpensive repair. However it's important to inspect related parts at the same time—idler pulley, drum rollers, and motor pulley—because a seized roller or rough pulley can wear a new belt out quickly. Confirm the belt is actually broken before replacing parts to avoid unnecessary expense.
Common Symptoms
Dryer motor runs but drum doesn’t tumble, loud motor noise, squealing or thumping at start, burning rubber smell, clothes remain wet after cycle.
Common Causes
- Normal wear and tear — belt degrades, cracks and snaps after extended use
- Stuck or seized drum rollers/idle pulley causing excessive friction and belt failure
- Foreign object or clothing snagging the belt or drum edge causing sudden break

Helpful Repair Tip
Open the dryer's access panel or rear cover and try to rotate the drum by hand. If the drum spins freely and you see a snapped or missing belt, the belt is the fault. If the drum resists or you hear grinding, inspect rollers/idler and replace them with the belt.
Frequently Asked Questions
Can I run the dryer with a broken belt?
No — do not run the dryer with a broken belt. The motor can run without turning the drum, which wastes electricity and can overheat or damage the motor. Also, a loose or snapped belt can rub on other components, creating heat or cutting wiring. Turn the dryer off and inspect before powering up again.
How much does it cost to replace a dryer belt and how hard is it to do?
Parts typically cost between $15 and $50 for an OEM or aftermarket belt; if you need rollers or the idler pulley, expect an additional $10–$60 per part. If you hire a technician, labor is commonly $100–$200 depending on region. Difficulty is moderate — most belt replacements require removing the top or rear panel and sometimes the front. Basic hand tools and photo documentation during disassembly make the job straightforward for a confident DIYer. Always unplug the dryer and follow the manufacturer’s service instructions.
