Whirlpool Dryer Idler Pulley Parts — Models & Compatibility

If your Whirlpool dryer is making a squealing noise or the drum won't turn smoothly, there's a good chance the idler pulley assembly has worn out. This hub covers the W10837240 idler pulley with bracket — a direct replacement for dozens of Whirlpool, Maytag, KitchenAid, and Kenmore dryer models. We'll show you which models it fits and how to verify yours is compatible.

Is This the Right Part for Your Model?

Check your dryer's model number first. You'll find it on a sticker inside the door frame or on the back panel near the bottom. Match it against the list below — this W10837240 pulley fits WED and WGD series models from the mid-2000s through recent years. It replaces older part numbers W10547290, W10118756, 3388674, and AP5988716, so if you have a quote for any of those, this is your part.

About This Replacement Part

The idler pulley keeps tension on the dryer belt, allowing the drum to spin properly. Over time, the bearing inside the pulley wears out — that's when you hear squeaking or grinding sounds. The W10837240 includes both the pulley wheel and the metal mounting bracket, which saves you time since the bracket often gets bent or corroded when the pulley fails. Pro tip: since you'll already have the dryer apart to install this pulley, consider replacing the belt at the same time. Belts wear gradually and you don't want to repeat this job six months later because the belt snapped.

Installation Tips

You'll need to remove the front panel to access the drum and belt assembly. Once you can see the old pulley, release the belt tension by pushing the pulley toward the motor, slip the belt off, then unbolt the bracket. The new assembly goes on in reverse. Make sure the pulley spins freely before you reassemble everything — if it feels stiff or gritty, you might have a defective part.
