Restore dryer belt tension with this genuine OEM Whirlpool Dryer Belt Idler Pulley - WP691366. The idler pulley keeps tension on the drum belt so the motor can turn the drum.

WP691366 is a genuine Whirlpool-manufactured dryer belt idler pulley used when the original part is worn, damaged, missing, leaking, noisy, or no longer performing correctly. The key to a correct order is matching the exact appliance model number and the original part design, not just the visible part name.

Fits These Brands / Families: Many Whirlpool-built dryers, especially common 29-inch dryer platforms with the lint filter on top, plus related Maytag, Kenmore, Amana, Estate, Roper, and Inglis models.

This part commonly replaces previous part numbers including 26000691366, 691366, W10612905, 99989677, 8207, 3394332, 688166, 4319391, 347277, 347226, 347034, 338946, 3388345, 337510, 337407, 337116, 239477, DE412.

Fitment / What To Verify: Verify the full dryer model number, idler arm/pulley style, belt routing, spring hook point, motor pulley condition, and whether the dryer uses the common top-lint-filter belt path. Some older friction-style idlers are replaced by a redesigned pulley assembly.

Please confirm fitment with your appliance model number before ordering.

• Common Symptoms: Squealing, screeching, drum not turning, belt falling off, burning rubber smell, or dryer stops after startup.
• Visible/Sensory Cues: Pulley wobble, seized bearing, flat-spotted belt, metal dust, worn arm, or belt riding off center.

Pro Tip: Consider replacing the belt and rollers while the dryer is open if they show wear. The idler is often one part of a worn drum-drive system.
