Understanding the Problem
A worn, stretched, or broken drum (drive) belt is a very common cause of a dryer drum that won’t turn, makes squealing/chirping noises, or spins intermittently. The drum belt wraps around the drum and connects to the motor/roller/idler assembly to turn the drum during a cycle. Below are practical diagnostic steps and how to replace the belt. 1) Confirm the symptom and prepare: unplug the dryer (and shut off gas if it’s a gas dryer). Symptoms that point to the belt include: drum not turning while motor runs, loud squeal when motor starts, or dryer tumbles intermittently. 2) Access the belt: depending on the model, you’ll typically remove the top or front panel. For many front-load style units: open the dryer door, remove the screws along the front opening, lift the front panel off (or release clips) or remove the two screws at the rear and tilt the top up to access the drum. Keep track of screws and use a phone to take a photo of belt routing before removal. 3) Inspect the belt: visually check for breaks, missing ribs, glazing (shiny worn surface), or fraying. Try to rotate the drum by hand — if drum turns freely but stops when motor runs, the belt is likely damaged or slipped. 4) Inspect related parts: examine idler pulley (for wear or seized bearing), drum rollers or glides (cracked, flat spots, or seized), and motor shaft/pulley. A seized roller or damaged idler will shorten belt life or break a new belt quickly. 5) Remove the old belt: release the tension on the idler pulley and slip the belt off the motor/idler pulleys and off the drum. Note how the ribs of the belt sit against pulleys and drum. 6) Fit the new belt: place the new belt around the drum (ribs as the original orientation), loop it through the idler and around the motor pulley, then apply tension by positioning the idler so the belt is taut. Ensure the belt sits in the drum’s groove correctly and is not twisted. 7) Reassemble and test: reattach the front/top panels and screws, plug in the dryer (and restore gas), run a short no‑heat cycle and observe the drum for smooth rotation and listen for abnormal noises. 8) If problem persists: if the drum still won’t turn, stalls, or you hear squeal immediately, replace the idler pulley and drum rollers/shaft bushings as needed. If motor is not turning or smells/burns, the motor or centrifugal switch may be failing. Safety note: always unplug the dryer and shut off gas (for gas dryers) before working on it. Wear gloves to avoid cuts and keep track of spring tension when releasing/reinstalling idler tensioners.

Helpful Repair Tip
To confirm the belt is the culprit, open the cabinet and manually spin the drum: if the drum spins freely when you turn it but stops when motor runs (or you hear a loud squeal), the belt is likely broken or the idler is failing. Also look for belt fragments or missing ribs.
Frequently Asked Questions
How do I know which belt size/part number I need for ADE3LRGS171TW01?
Check the dryer’s model and serial tag (usually inside the door opening or on the back). Use that exact model number on parts supplier sites to find the OEM belt. If you don’t have the exact OEM part, measure the old belt (length and width) or note common universal sizes like 4L330 or 4L340, but verify fit before installation.
Can I run the dryer with a temporary or universal belt?
You can temporarily use a correctly sized universal belt (matching length and width) but avoid running the dryer at high heat for long periods until you confirm the idler and rollers are good. A temporary or incorrect belt may slip, overheat, or fail if related components are worn.
