Understanding the Problem
If your dryer drum no longer turns or the motor runs but the drum doesn't, the most likely cause is a broken or slipped drum belt. The belt wraps around the drum and connects to the motor and an idler pulley; when it fails the motor can spin but it can't turn the drum. A snapped belt is a common wear item — it usually develops cracks, frays, or stretches over many years of use and then gives out. Other components that contribute to belt failure include a seized idler pulley or worn drum rollers/bearings. These parts create extra resistance that accelerates belt wear and can cause premature breakage. Replacing the belt alone will fix the symptom, but inspect idler pulleys and rollers while you have access to the drum to prevent repeating the repair soon after.
Common Symptoms
Drum won't turn or turns intermittently; motor runs or hums; screeching/grinding noise before failure; visible belt fraying or snapped belt inside cabinet.
Common Causes
- Normal wear and aging of the drum belt leading to cracks or snapping
- Seized or worn idler pulley/roller increasing belt stress and causing premature failure
- Drum misalignment or damaged drum bearings creating extra resistance and wearing the belt

Helpful Repair Tip
Open the dryer door and try rotating the drum by hand. If it spins freely but the motor runs without turning the drum, visually inspect under the dryer front panel for a snapped belt or loose belt lying in the cabinet. If the belt is intact but badly glazed or thin, replace it. While open, check the idler pulley and rollers for free, quiet rotation and minimal play.
Frequently Asked Questions
How difficult is it to replace a dryer belt and how long does it take?
Replacing a dryer belt is a moderate DIY job for someone comfortable with basic hand tools. Typical time is 30–90 minutes depending on model and how easily panels come off. You generally disconnect power, remove the front or top panel, release the belt from the idler, slip the new belt over the drum, and reassemble. Consult your model-specific service manual or a trusted tutorial for the correct belt routing and safety steps.
Can I keep using my dryer if the belt is broken or slipping?
No — you should not run a dryer with a broken or badly slipping belt. The motor may run and overheat, and running the dryer without a functioning belt can damage the motor or other components. Replace the belt (and any worn idler pulley or rollers you find) before using the dryer again.
