Understanding the Problem
The dryer belt is a reinforced rubber loop that wraps around the drum and connects to the motor pulley (often via an idler pulley). When it snaps or stretches beyond use, the motor will run but the drum won’t turn — or the drum will slip and make squealing or thumping noises. A broken belt is one of the most common mechanical failures on belt-driven dryers and is usually straightforward to diagnose and replace. Because dryer designs and belt sizes vary by make and model, you’ll need the dryer’s model number to order the exact replacement belt and any related parts (idler pulley, drum rollers, springs). Before replacing parts, check for other damage that may have caused the belt to fail (e.g., seized drum rollers, foreign objects, worn drum seals) — replacing the belt without addressing the root cause can cause the new belt to fail prematurely.
Common Symptoms
Motor runs but drum does not tumble; loud thumping or squealing when the motor runs; visible snapped or sagging belt; dryer stops tumbling mid-cycle.
Common Causes
- Normal wear and age — belt becomes brittle or stretched and snaps
- Obstructed or seized drum rollers/axles causing excessive belt wear
- Faulty idler pulley or motor pulley increasing belt stress
- Overloading the dryer or foreign objects caught between drum and bulkhead

Helpful Repair Tip
Confirm a broken belt by opening the dryer (disconnect power first), try turning the drum by hand — if it turns freely without the motor engaged or the belt is visibly snapped/sagging, the belt is the likely culprit. Note your dryer’s model number (usually inside the door or on the back) and use it to order the exact belt.
Frequently Asked Questions
Can I replace the dryer belt myself?
Yes — replacing a dryer belt is a common DIY repair if you’re comfortable with basic hand tools and follow safety precautions. Unplug the dryer first, take photos while disassembling to aid reassembly, remove the front or rear access panel depending on model, slip off the old belt, route the new belt around the drum and pulleys following the manufacturer’s routing diagram, and reassemble. If your dryer uses interior access points or spring clips, take extra care. If you’re unsure or the motor/rollers are damaged, consider a pro.
How much does a belt replacement usually cost and how long does it take?
Parts-only cost: typically $15–$60 for the belt plus $10–$40 each for idler/roller kits depending on brand. Labor (if hired): usually $100–$200 depending on local rates and access difficulty. Time: most DIY repairs take 30–90 minutes; a technician can often complete it in 30–60 minutes. Final cost/time depend on whether additional parts (rollers, idler, motor) need replacement.
