Understanding the Problem

The dryer drive belt on Kenmore model 417.97042700 is a wear item that wraps around the drum and connects to the motor pulley and idler. Over time the belt can become glazed, cracked, stretched, frayed, or break outright — causing the drum to not turn or to slip during operation. A failed belt is one of the most common reasons a dryer will run but not tumble or will make squealing or rubbing noises. Replacing the belt is a straightforward repair for someone comfortable with basic appliance disassembly. The job typically requires unplugging the dryer, releasing belt tension (idler), removing the old belt from the drum, routing the new belt around the drum and motor pulley/idler, and reassembling. While the belt is the usual culprit, inspect related parts (idler pulley, drum rollers, motor shaft) because seized rollers or a worn idler can quickly wear out a new belt if not addressed.

Common Symptoms

Dryer motor runs but drum does not tumble; loud squealing or rubbing noise when running; burning rubber smell; visible broken or frayed belt; drum slips or turns intermittently.

Common Causes

  • Drive belt worn, cracked, stretched, frayed, or broken from age and use
  • Belt jumped off the idler or motor pulley or was installed incorrectly
  • Worn drum rollers/shaft or seized idler/motor causing extra load that damages the belt

Frequently Asked Questions

How do I confirm which belt fits my Kenmore 417.97042700?

Locate the model and serial tag (usually inside the door opening or on the back panel) and use that exact model number on appliance parts websites or at a dealer. If you already have the old belt, note its length and rib count and match those specs when ordering. When in doubt, provide the full model/serial to the parts supplier so they can confirm compatibility.

Can I replace the dryer belt myself, and how hard is it?

Yes — many DIYers can replace the belt. Typical tools: screwdriver or nut drivers, socket set, and sometimes a putty knife to release clips. Turn off power (unplug or switch off breaker) and follow step-by-step guides or video for your specific model. Expect 30–90 minutes depending on experience. If the idler, rollers, or motor bearings are worn, plan additional time and parts. If you are uncomfortable with electrical or mechanical work, contact a qualified appliance technician.
