Understanding the Problem
What this part is: The ADE3LRGS171TW01 is a dryer drum belt — the looped rubber belt that wraps around the dryer drum and connects to the motor/drive pulley (and idler pulley on many models). It transfers motor torque to turn the drum so clothes tumble. Diagnostic & repair steps: 1) Confirm the symptom: Unplug the dryer (or turn off circuit breaker). Try rotating the drum by hand from the front; a healthy drum should turn smoothly and with moderate resistance. If the drum is loose or will not turn at all while the motor runs, a broken or slipped belt is likely. 2) Visual inspection: Remove front/top or back access panel per your model. Look for a snapped belt, missing ribs, glazing, heavy fraying, or a belt that has slipped off the drum. Also inspect drum support rollers, idler pulley, motor pulley and tensioner for wear — a bad idler or seized roller often destroys belts quickly. 3) Check for smells/noise: A strong burning rubber smell, loud squealing during startup, or a belt that slips under load are classic belt-failure signs. 4) Remove old belt: With power off, release tension on the idler (or remove motor mounting bolts on older designs), slip belt off motor pulley and drum, and remove the drum if needed to access the belt path. Keep note of belt routing — most belts have ribs facing the drum. Take photos for reassembly. 5) Inspect adjacent parts: Examine drum rollers, glides/slide pads, idler pulley, motor shaft, and the drum itself for grooves or damage. Replace any worn parts while you have the dryer apart — these cause new belts to fail prematurely. 6) Install new belt (how to fix): Route the new ADE3LRGS171TW01 around the drum with the ribbed side facing the drum (or follow the belt orientation from your model). Thread the belt around the idler and over the motor pulley so the idler applies tension properly. Re-seat the drum and spin it by hand to verify even tension and that the drum turns smoothly. 7) Reassemble & test: Reinstall panels, restore power, run an empty cycle and listen for smooth operation. Confirm drum spins from cool start and heat cycles behave normally. 8) Final checks: After a few cycles, re-check for unusual noises, slipping, or burning smells. Safety note: Always disconnect power before doing any repairs. For gas dryers, turn off the gas supply if you need to move the appliance or work near the gas connections. If you are uncomfortable with electrical or gas work, hire a qualified technician.

Helpful Repair Tip
With the dryer unplugged, try rotating the drum by hand while watching the motor and idler: a snapped belt will let the drum spin freely while the motor pulley turns, so you can confirm belt failure quickly.
Frequently Asked Questions
How long does a dryer drum belt typically last?
A drum belt commonly lasts 5–10 years depending on usage, load balance, and whether supporting parts (idler, rollers) stay in good condition. Heavy loads or worn pulleys shorten belt life.
Can I run the dryer with a broken belt?
No. A broken belt prevents the drum from turning; running the dryer can damage the motor (it may overheat trying to drive a stalled drum) and could be a fire risk if the belt is rubbing. Replace the belt before further use.
