Understanding the Problem
The drive belt on a Kenmore 100 Series dryer wraps around the drum and connects it to the motor. Over time heat, friction and normal wear cause the belt to stretch, fray or break. When the belt fails the motor may run but the drum won't tumble (or will tumble intermittently), which prevents clothes from drying and can produce squeals or a burning-rubber smell. Replacing the belt is a common and usually straightforward repair, but the correct belt varies by exact model. Before ordering parts you should confirm the dryer model number on the tag (usually inside the door frame or on the back) because the replacement belt length and rib pattern must match. While replacing the belt it's a good idea to inspect the idler pulley, drum rollers/glides and motor shaft for wear — those components often cause premature belt failure and are inexpensive to replace at the same time.
Common Symptoms
Motor hums or runs but drum doesn't tumble; drum tumbles intermittently; squealing or rubbing noises when running; burning rubber smell; visible fraying or a snapped belt when you inspect the drum.
Common Causes
- Belt worn, glazed or frayed from age and heat exposure
- Idler pulley, drum rollers or drum glides seized or worn—adding extra stress and causing the belt to wear or snap
- Overloading the dryer or a foreign object jam that causes the belt to slip or tear

Helpful Repair Tip
Unplug the dryer, then try to rotate the drum by hand. If the motor runs when the dryer is on but the drum does not turn (or only turns with a lot of resistance), the drive belt is likely broken or slipped off. Always verify visually by removing the access panel before ordering the part.
Frequently Asked Questions
How can I tell for sure the belt is the problem?
Safety first: unplug the dryer. Remove the access panel (or open the front) so you can see the drum and belt. Manually rotate the drum—if it spins freely but the motor runs with the drum stationary when turned on, the belt is likely broken or off the pulleys. A visual inspection will show frayed edges, cracking, glazing or a snapped section. If you see heavy wear on the idler pulley or rollers, replace those too.
Can I replace the dryer belt myself and what do I need?
Yes — most people can replace a Kenmore dryer belt with basic tools. Unplug the dryer, remove the top or front access panel to reach the drum, note the belt routing (take a photo), release tension on the idler pulley, slip the belt off the motor pulley and drum, then install the new belt around the drum and onto the motor pulley and idler. Tools: screwdriver or nut driver set, socket set, putty knife (to release clips), and gloves. Allow 30–60 minutes. If idler, rollers, or the motor shaft show wear, replace them while you have the dryer open.
