Understanding the Problem
Brief explanation: The most commonly referenced “pulley” on a Whirlpool WGD6200SW0 dryer is the idler (tension) pulley that keeps the drive belt tight, or the drum support rollers/pulleys that help the drum turn smoothly. When these components wear out the dryer squeals, grinds, the drum can bind or not turn, and belts can fray or break. Step-by-step diagnostics and repair (practical how-to): 1) Safety first: Unplug the dryer and shut off power at the breaker. Confirm power is off. 2) Tools & prep: Phillips and flat screwdrivers, nut driver (1/4" & 5/16"), socket set, work gloves, replacement pulley/roller, putty knife (to release top), flashlight. 3) Access the drum: Remove lint screen, use a putty knife to release the top panel clips (or remove top screws on some models). Lift top and prop or remove. Remove front panel screws (and disconnect door switch connector if needed). Slide the drum forward and rest it on the front lip or remove it if necessary to access the idler area. 4) Visual inspection: With the drum out or pulled forward, inspect the idler pulley (tensioner) near the motor and the drum support rollers around the back/front of the drum. Look for cracked plastic, separated rubber, bearing play, wobble, flat spots on rollers, or metal-to-metal contact. 5) Manual test: Spin each pulley/roller by hand. A good pulley spins freely and silently; a worn one will be rough, gritty, noisy, or have side-to-side play. Also check the belt for glazing, fraying, or damage. 6) Confirm the bad part: If the drum is noisy only when loaded or under tension, the idler pulley is often the culprit. If the drum rattles or wobbles when spun by hand, drum support rollers or rear drum bearing/glide are likely. 7) Remove belt and pulley: Slide the belt off the motor pulley and drum. Remove the idler assembly mounting screw(s) and pull the idler/pulley assembly out. For drum rollers, remove the retaining clips/nuts and pull bearings/rollers free. 8) Install replacement: Fit the new idler or new drum rollers in the exact orientation. Ensure the pulley flange is toward the belt and that rollers spin freely. Re-route the belt: loop it around the drum, under/through the idler so the idler applies tension to the belt against the motor pulley. Make sure belt ribbed side engages correctly. 9) Reassemble and test: Reinstall the drum and front panel, reconnect door switch, lower top and secure, reconnect power. Run a test cycle empty and listen for noise; verify drum spins smoothly and belt stays aligned. 10) Final checks: After a short run, recheck for unusual heat, smell of burning (indicates belt slip) or any wobble. Safety note: Always unplug the dryer before any disassembly. Use care with the drum — it’s heavy and edges can pinch. If you’re unsure about electrical connections or moving heavy parts, consider a professional repair.

Helpful Repair Tip
Spin the suspected pulley/roller by hand: any roughness, grinding, wobble, or visible play means it should be replaced. If the idler pulley doesn't spring to tension or the belt hangs loose, replace the idler.
Frequently Asked Questions
How do I know if I should replace the idler pulley or the drum rollers?
If the noise is a high-pitched squeal or the belt slips under load, the idler pulley is often bad. If the drum wobbles, bangs, or makes a low thumping noise and feels loose when spun by hand, drum support rollers or rear bearing/glide are likely. Inspect both — replace any part that shows rough rotation, play, or visible damage.
Can I keep using the dryer if the pulley is noisy?
You can for a short time, but it’s not recommended. A failing pulley or roller will accelerate belt wear and can cause the belt to break suddenly, which may lead to more costly damage. Replace noisy pulleys/rollers promptly to avoid secondary failures.
