Understanding the Problem
When a dryer belt breaks the drum will stop turning even though the motor may run. Modern dryers use a looped drive belt wrapped around the drum and the motor/idler assembly; when that belt snaps the drum loses drive and clothes won't tumble. In many cases you’ll hear a loud thump or a sudden change in noise right before the drum stops turning, and sometimes you’ll also notice a burning rubber smell from a belt that’s frayed or slipping. A broken belt is a common, straightforward repair compared with motor or transmission failures. However, the belt can fail for several reasons: normal wear and aging, a seized idler pulley or drum roller that places extra stress on the belt, or repeated overloading. Confirming the belt is the issue before buying parts will save time and money—often the fix is a single part and 30–90 minutes of labor for someone comfortable with basic appliance repair.
Common Symptoms
Drum does not turn but motor runs (or hums), loud thump or snapping noise, burning rubber smell, shredded belt pieces found inside the cabinet.
Common Causes
- Normal belt wear and fatigue from long service life
- Seized or worn idler pulley/drum rollers causing extra strain
- Overloading the dryer or repeated heavy loads that stretch/overstress the belt

Helpful Repair Tip
Open the dryer front or rear panel and try to spin the drum by hand. If the drum turns freely with no motor sound or the belt is visibly snapped/frayed, the drive belt is the faulty part. Also inspect idler pulley and drum rollers for wear—if they’re seized or noisy, replace them with the belt.
Frequently Asked Questions
Can I replace a dryer belt myself?
Yes, many homeowners can replace a dryer belt themselves if they are comfortable removing panels and working with basic hand tools. Typical steps: unplug dryer, remove front or rear panel per your model, note belt routing (take photos), remove the old belt, check idler and rollers, install new belt routed around drum and motor/idler, reassemble and test. Allow 30–90 minutes depending on model and experience. If the cabinet is rusted, clips are stuck, or you’re unsure about electrical connections, call a pro.
How much does it cost to replace a dryer belt?
Parts alone are inexpensive—usually $10–$40 for the belt, $10–$40 each for idler pulley or drum rollers if needed. If you hire a technician, total cost including labor typically runs $100–$250 depending on service rates and whether additional parts (rollers, motor) are required. Exact cost depends on dryer brand and local labor rates.
