Understanding the Problem
If your Kenmore 100 Series dryer stops tumbling or the drum turns intermittently, the dryer drum belt is a common cause. The belt wraps around the drum and connects it to the motor drive; over time it stretches, cracks, or breaks and will prevent the drum from rotating even though the motor runs. You may also hear a thumping, rubbing or squealing noise as a failing belt slips against the drum. A broken or worn belt can be caused by normal wear, or by secondary issues such as a seized drum roller, sticky idler pulley or misaligned drum that accelerates belt wear. Replacing the belt is a straightforward repair on most 100 Series Kenmore models, but it's a good idea to inspect rollers, idler pulley and motor shaft for damage while you’re inside the cabinet so you don’t have to reopen it soon after.
Common Symptoms
Dryer motor runs but drum doesn't turn (or turns intermittently); loud thumping, squealing or rubbing noises; burning rubber smell; drum slipping under load.
Common Causes
- Worn, stretched, cracked or broken drum belt
- Seized/rough drum rollers or worn roller bearings causing excessive belt wear
- Faulty or sticky idler pulley that allows belt to slip or rub
- Misaligned drum or foreign object jamming the drum and shredding the belt

Helpful Repair Tip
Confirm a bad belt by manually trying to rotate the drum with the dryer off — if the drum spins freely but the motor runs without turning the drum, or you see a visible crack, fray or a completely broken belt when you open the cabinet, the belt needs replacing.
Frequently Asked Questions
How do I find the exact belt part number for my Kenmore 100 Series dryer?
Locate the model and serial tag (usually on the door opening, door frame or back panel). Use the full model number when searching parts online or inputting it at an appliance parts supplier to get the exact belt listed for your model. If you can’t find the tag, take a photo of the dryer and consult a parts dealer.
Can I replace the dryer belt myself and how long does it take?
Yes — most belt replacements are DIY-friendly with basic tools (screwdriver, nut driver). Typical steps: unplug the dryer, remove the front or rear access panel depending on model, release idler tension, remove the old belt, route the new belt around the drum and pulleys, re-tension, and reassemble. Expect 30–60 minutes for a first-timer. If you find worn rollers or a damaged idler, replace them at the same time to avoid repeating the repair.
