Understanding the Problem
A broken dryer belt is a common reason the drum will not tumble even though the motor may run or you hear the motor trying to start. The belt wraps around the drum and the drive pulley; when it snaps or slips off, the drum loses traction and stops turning. Depending on your model (CCJ / NBC or similar), the symptom can be immediate (sudden snap) or gradual (belt frays and slips under load). Replacing the belt usually fixes the problem, but you should inspect associated parts while you have the cabinet open. A seized idler pulley, worn drum rollers, or a motor issue often causes excessive belt wear and will ruin a new belt quickly if left unaddressed. Always confirm the belt is the failed component before buying parts and follow safety steps (unplug the dryer) prior to disassembly.
Common Symptoms
Drum does not turn (tumble) while motor may sound like it's running; loud snapping or thumping noise followed by no tumbling; visible frayed or missing belt under the cabinet.
Common Causes
- Worn or frayed drive belt that finally snaps
- Failed idler pulley or tensioner allowing belt to slip off
- Worn or seized drum rollers or bearings causing extra belt wear

Helpful Repair Tip
Open the dryer door and try to rotate the drum by hand. If the drum turns freely with no resistance or you hear the motor running with the drum stationary, the belt is very likely broken or slipped off. Also check under the drum for a frayed or missing belt before ordering parts.
Frequently Asked Questions
Can I run the dryer if the belt is broken?
No. If the belt is broken the drum will not turn. Running the dryer with a broken belt can overheat the motor or cause additional damage. Unplug the appliance and inspect or replace the belt before using it again.
How much does it cost and how long does it take to replace a dryer belt?
Parts typically cost between $15–$60 for a belt and $30–$120 for a repair kit that includes idler and rollers. Labor if using a technician is commonly $100–$200 depending on region. If you do the repair yourself, most belt replacements take 30–90 minutes for someone comfortable with basic appliance disassembly; add extra time to inspect and replace rollers or the idler if needed.
