Understanding the Problem
The dryer drive (or drum) belt wraps around the drum and connects to the motor via an idler pulley. When the belt snaps or slips off, the motor can run but the drum will not turn, so clothes won't tumble and won’t dry. You may also hear a loud thump, squeal, or a grinding sound when the belt fails. A broken belt is a common wear-item failure caused by age, heat, or an obstruction that jams the drum. Replacing the belt is a straightforward repair on most dryers, but you should also inspect the idler pulley, drum rollers, and motor shaft for wear — a failed pulley or seized roller will quickly ruin a new belt if not addressed at the same time.
Common Symptoms
Drum spins intermittently or not at all while motor runs, loud thumping or squealing, burning rubber smell, visible belt damage or belt off the drum.
Common Causes
- Normal wear and deterioration of the drive belt
- Idler pulley or motor pulley failure causing excess wear or belt slip
- Seized drum rollers or drum shaft damage that overload the belt
- Foreign object or sock jammed between drum and bulkhead, cutting the belt
- Improper belt installation or misaligned pulleys from prior repair

Helpful Repair Tip
With the dryer unplugged, try turning the drum by hand. If the motor runs when you start the dryer but the drum won’t turn, or the belt is visibly hanging loose or shredded, the belt is the likely culprit.
Frequently Asked Questions
Can I keep using the dryer if the belt is broken?
No. Running the dryer with a broken belt can cause the motor to overheat and may damage the idler pulley, motor shaft, drum rollers, or other components. Unplug the dryer and avoid using it until the belt and any damaged parts are replaced.
Can I replace a dryer belt myself and how hard is it?
Yes — many dryer belt replacements are doable for a competent DIYer with basic tools (screwdrivers, nut drivers, sometimes a socket). Typical steps: unplug the dryer, access the belt by removing the dryer front or back panel (model-dependent), remove the old belt from the drum and motor pulley, inspect and replace worn rollers/pulleys, route and tension the new belt, then reassemble. Take photos during disassembly and follow a model-specific guide for best results. If you’re uncomfortable or the motor/rollers are damaged, consider a professional repair.
