Understanding the Problem
Many Whirlpool dryers (including model WGD6200SW0) use a drive belt, idler pulley and drum rollers to support and turn the drum. When those parts wear or fail you’ll get squealing, scraping, the drum may wobble or stop turning, or the belt may break. Below are practical diagnostic and repair steps you can follow. 1) Verify symptoms and prepare: Unplug the dryer (or turn off its circuit breaker) and, for gas units, turn off the gas supply. Remove any clothes from the drum. Note the symptom: squeal when turning, drum won't turn, burning rubber smell, visible wobble. 2) Access the drum assembly: For WGD6200SW0 you typically remove the top panel and front panel to reach the drum, belt and rollers. Remove the lint screen and the screws under the lint housing, then lift the top and unclip the front. Keep track of screws and connectors. 3) Inspect the drive belt: Visually check the belt for cracks, fraying, glazing (shiny hard areas) or broken strands. With the belt removed (see step 6) you should be able to spin the drum freely by hand. A glazed, stretched or broken belt must be replaced. 4) Check drum rollers and axle bearings: Rotate the drum by hand and listen/feel for roughness or rumbling. Grab the drum at opposite sides and rock it to check for side-to-side play. Excess play or a pronounced wobble indicates worn rollers or a damaged axle/shaft. Inspect rollers for flat spots, roughness or seized bearings. 5) Inspect the idler pulley: Locate the idler assembly (tensioner) that keeps belt tension. With the belt off, spin the idler pulley by hand—if it’s noisy, rough, or doesn’t spin freely, the pulley bearing is bad. Check the idler spring for proper tension and look for wobble in the idler arm. 6) Remove the belt and drum: Release the idler tension and slip the belt off the motor and drum. Slide the drum forward and lift it out of the cabinet to access rollers and rear bearing. Inspect rear drum bearing (if equipped) and front roller support. 7) Replace worn parts: Replace any worn rollers, the idler pulley (or idler kit), and the drive belt together. It’s best practice to replace rollers, belt and idler as a set if one component failed from wear—this prevents repeat labor. 8) Reassembly and test: Refit the drum, loop the new belt around the drum and motor pulley, route it over the idler so it has correct tension, reattach front/top panels, reconnect power (and gas if applicable). Run the dryer empty and listen for normal operation — smooth, quiet rotation and no wobble. How to fix (concise replacement steps): - Tools needed: Nut drivers (1/4" & 5/16"), 7/16" wrench or socket, putty knife (for clips), replacement parts, work gloves. - Remove power/gas and lint screen. Remove screws under lint housing and lift top. Remove front panel to access drum. Remove belt by releasing idler tension and slipping belt off. Remove drum. Replace drum rollers (pull old rollers off shaft and press new ones on; some rollers have retaining clips). Replace idler pulley (unbolt and swap). Install new belt: loop belt around drum with arrow marking toward drum interior, place drum in cabinet, route belt around motor pulley and under idler, apply tension and verify belt tracks on drum rib. Reassemble panels and test. Safety note: Always disconnect power before disassembly and, for gas models, turn off the gas supply. Work on a cool dryer and avoid forcing electrical connectors—tag them if necessary. If you are unsure about gas connections or the ignitor assembly after reassembly, call a qualified technician.

Helpful Repair Tip
Spin the drum by hand with the belt removed: if the drum spins rough or you feel catches, the rollers or rear bearing are bad. If the drum spins freely but the motor runs and the drum doesn’t turn with the belt on, the belt is likely slipped or broken.
Frequently Asked Questions
How do I know if the idler pulley or the belt is the problem?
Remove the belt and spin the idler pulley by hand — if it's noisy, rough, or doesn't spin freely, the idler is bad. If the idler spins freely but the belt shows glazing, cracks or is broken, replace the belt. Also check drum rollers: if the drum still feels rough with the belt removed, rollers (or rear bearing) are likely at fault.
Can I replace just the belt and leave the rollers and idler if they're noisy but still working?
You can, but it's not recommended. Worn rollers or a failing idler will wear out a new belt quickly and you'll likely repeat the repair. Best practice is to replace belt, rollers and idler together when any of them show wear.
