Understanding the Problem
Brief explanation: The dryer belt (drum belt) wraps around the dryer drum and connects to the motor and idler pulley so the drum can rotate. On a KEYS850LE1 (or similar models) the typical failure is a worn, cracked, or snapped belt that stops the drum from turning — you may hear the motor run but the drum doesn't turn, or you may hear squealing or rubbing noises. Step-by-step diagnostic and repair steps: 1) Safety first: unplug the dryer and shut off gas if it is gas-powered. Work with the dryer disconnected from power. 2) Confirm the symptom: Try to turn the drum by hand with the dryer off. If the drum spins freely but the motor runs without turning it, or you feel no resistance while the motor runs, the belt is likely broken or slipped. 3) Remove access panels: Depending on your model you will either remove the front panel (top screws and clips) or the rear panel. Common sequence: open lint screen, remove two screws under the top to lift top, or remove rear access panel screws. Keep track of screws. 4) Inspect visually: Look for a snapped belt, melted/ragged belt edges, or a belt hanging loose. Also inspect the idler pulley and motor pulley for wear, and drum support rollers or glides for roughness — a seized idler or worn rollers commonly ruin belts quickly. 5) Remove the old belt: If the belt is intact but loose, slide it off the drum and down from the idler and motor pulley. If snapped, pull the pieces out carefully so you can route the new belt properly. 6) Inspect related parts: Spin the motor pulley and idler by hand. Replace a noisy or seized idler pulley (idler) and any worn drum rollers/supports or felt seals. Replacing the belt alone often results in repeat failure if these are bad. 7) Install the new belt: Position the belt around the drum so the ribbed side contacts the drum surface as required by your belt design (ribs usually face inward to sit on motor pulley). Feed the belt under/around the idler and around the motor pulley so proper tension is applied. Many dryers route the belt in a figure-8 pattern around idler then motor; check photos or the service sheet for your model. 8) Reassemble the dryer: Reinstall the front or rear panel and any screws you removed. Reconnect the dryer to power (and gas) and run a short test cycle. 9) Test: Start the dryer empty for 1–2 minutes. The drum should turn smoothly without squeaks and the motor should not be struggling. Check for any rubbing or unusual noises. 10) Final check: After a test run inspect for belt tracking (centered on drum) and check that lint screen and venting are clear. Safety note: Always disconnect power before working on the dryer. If you are not comfortable working with appliance disassembly or gas connections, hire a qualified technician.

Helpful Repair Tip
Confirm a broken belt quickly: open the lint trap and try to rotate the drum by hand with the dryer unplugged — if the drum spins freely or you see a loose/snappped belt under the drum, the belt is the likely culprit.
Frequently Asked Questions
How can I find the exact belt part number for KEYS850LE1?
Locate the dryer model tag (usually on the door opening or rear panel) and use that full model number on appliance parts sites or the manufacturer's parts lookup. If you can't find it, take a photo of the old belt and dryer interior and match it with parts sellers. Do not assume belt size — belts of similar appearance can have different lengths and rib patterns.
Can I operate the dryer with a broken belt until I get a replacement?
No. Running the dryer with a broken or slipping belt can cause the motor to overheat and may damage the motor pulley, idler, or drum bearings. Unplug the dryer until the belt and any worn components are replaced.
