Understanding the Problem
A broken dryer belt is a common reason a dryer drum will not turn even though the motor runs or you hear the motor trying to start. The drive belt loops around the drum and the motor/drive pulley; when it snaps or slips off, the motor can spin but the drum won’t rotate or will rotate with difficulty. Left unaddressed, a broken belt will prevent clothes from tumbling and can cause uneven drying, overheating of the motor, or extra wear on idler pulleys and drum rollers. Replacing the belt is usually straightforward and inexpensive, but it's wise to inspect related parts (idler pulley, rollers, tension spring, drum glides) because a worn component can break a new belt shortly after replacement.
Common Symptoms
Drum won’t rotate or tumbles intermittently, motor runs but no tumbling, loud squealing or scraping noises, clothes remain wet after a cycle.
Common Causes
- Age and wear: belts stretch, crack, or fray over time and eventually break.
- Worn or seized drum rollers/shaft bearings that increase belt friction and cause premature failure.
- Faulty idler pulley or tension spring that allows the belt to slip or run off the pulley.

Helpful Repair Tip
Open the dryer door and try to manually spin the drum. If it spins freely or the motor runs but the drum doesn’t turn, visually inspect for a snapped belt at the front or rear of the drum. Also check for rubber debris from a shredded belt.
Frequently Asked Questions
Can I replace a broken dryer belt myself?
Yes. Replacing a dryer belt is a common DIY job if you are comfortable with basic hand tools. Typical steps: unplug the dryer (and shut off gas if a gas dryer), remove the top/control panel or front panel depending on model, release the drum and remove the old belt, inspect rollers/pulley, route the new belt around the drum and pulley per the dryer’s diagram, reassemble and test. Allow 30–90 minutes depending on model and experience.
How much does it cost to fix a broken dryer belt?
Parts: a replacement belt typically costs $10–$40. If other parts (idler pulley, rollers, glides) need replacement, expect an additional $15–$80 in parts. If you hire a technician, labor can add $80–$200 depending on local rates and access difficulty. Always check your dryer model number to order the correct belt and consider replacing worn rollers/pulley at the same time to avoid repeat failures.
