Understanding the Problem
Why this matters: The idler pulley (sometimes called the tensioner pulley) keeps proper tension on the drum belt so the drum turns smoothly. On a Whirlpool/Maytag-style dryer like the WGD6200SW0 a failing pulley will cause squealing, rubbing, a loose or shredded belt, or a dryer that won’t tumble or tumbles intermittently. Step-by-step diagnostic and repair instructions: 1. Safety first: Unplug the dryer from power. If this is a gas dryer, turn off the gas supply and disconnect the gas line at the shutoff or follow local codes for gas appliance service. 2. Confirm the symptom: Manually try to rotate the drum (with the dryer off). Listen for grinding/squeal, feel for resistance, and watch for wobble. If the drum is hard to turn or you hear metal-on-metal or bearing noise, the idler or drum rollers are suspect. 3. Remove access to the belt/roller area: On most Whirlpool-style dryers (WGD series) you usually remove the lint screen and the screws under the lint-trap to lift the top, or remove the top panel clips. Then remove the front panel screws and lift the front panel off. If you’re unsure, consult the model’s service sheet. Keep track of screws and clips. 4. Inspect visually: With the front off and the belt exposed, inspect the idler pulley assembly (mounted on a spring-loaded bracket near the motor). Look for cracked or missing pulley grooves, wobble on the pulley shaft, a seized or rough bearing, or a torn/deteriorated rubber wheel. 5. Check belt and rollers: Inspect the drum belt for glazing, fraying, or breakage. Also check drum support rollers (rear and front depending on design) for play or roughness — often several parts wear together. 6. Remove the belt: Release tension by pushing the idler toward the motor to slack the belt, then slip the belt off the motor pulley and drum. Note belt routing before removal or take a phone picture. 7. Remove the idler pulley: Support the spring bracket, remove the retaining fastener(s) or pin holding the pulley to the bracket, and slide the pulley off. On some models you remove the whole bracket assembly. Inspect the bracket for bent mounting or badly worn pivot holes. 8. Replace the part: Install the new idler pulley (or assembly). If the bracket or shaft is worn, replace the entire idler assembly. Refit the belt around the drum and motor pulley, position the belt in the drum groove, and pull the idler into place so it tensions the belt properly. 9. Test rotation before reassembly: Turn the drum by hand to confirm smooth rotation and correct belt tracking. Reconnect power (and gas if applicable) just for a short powered test: run the dryer briefly to confirm quiet operation and that the drum turns normally. 10. Reassemble panels: With the machine running quietly and the drum tumbling, disconnect power again, reattach the front panel, top, and lint trap screws. Restore power and test a full cycle. How to fix (practical tips): Replace the idler pulley when the wheel is cracked, bearing is rough/seized, there is side-to-side play, or the pulley does not spin freely. If the belt shows wear or the drum rollers are rough, replace them at the same time — it’s common for multiple wear items to fail together. Safety note: Always disconnect electrical power before servicing. For gas models, shut off gas and label any disconnected lines. If you’re uncomfortable with gas or internal electrical work, hire a qualified technician.
Common Symptoms
Squealing or grinding noise when dryer starts, intermittent or no tumbling, belt wear or shredding, burning rubber smell, drum wobble.
Common Causes
- Worn or seized idler pulley bearing
- Damaged pulley wheel (cracked or worn groove)
- Bent idler bracket or loose mounting allowing misalignment
- Worn drum belt or drum support rollers increasing load on the pulley

Helpful Repair Tip
Lift and spin the idler pulley by hand after removing the belt — if it feels rough, gritty, or has side-to-side play, replace it. Also flex the belt to check for glazing or cracks; a glazed belt plus pulley noise = replace both.
Frequently Asked Questions
Can I run the dryer if the idler pulley is noisy?
No — running the dryer with a failing idler pulley risks shredding the belt, overheating the motor, or causing further damage to the drum and rollers. Turn the dryer off and replace the pulley as soon as possible.
How long does it take to replace an idler pulley on a WGD6200SW0?
For a DIYer with basic tools expect 30–60 minutes. Time varies if you also replace the belt, rollers, or need to remove/install gas connections. Allow extra time if you’re unfamiliar with dryer disassembly.
