DifficultyModerate

Typical time45 to 75 minutes

ToolsScrewdrivers or nut drivers, Pliers

Safety. Unplug the dryer before you start (and switch off the breaker if it is hard-wired). A blocked vent is a fire risk, so always clear the cause of any overheating.

Signs it has failed

A squealing or chirping noise from the front of the dryer
A thumping noise with each turn
A belt that keeps slipping off or wearing quickly
A pulley that wobbles or no longer spins freely

Check before you buy

With the belt off, spin the pulley by hand and feel for roughness or play
Check the spring arm moves freely and holds tension
Replace it when you fit a new belt if it is worn

What replacing it fixes: if the signs above match your dryer and the checks point to this part, fitting a new one should clear those faults. If the symptoms continue, the cause is elsewhere (a control board, a sensor or a blocked vent or hose).

How to replace it

Unplug the dryer and open the cabinet for belt access
Release the belt tension and remove the belt
Unscrew or unclip the old idler pulley assembly
Fit the new one and refit the belt
Close up and test

Guide steps are typical for this type of part. Layouts differ between models, so follow your own manual where it differs.

Getting the right part

Pulleys vary by arm design and wheel size. Match the part number and your model.

Check your model number first. It is on the rating plate — usually inside the door frame, on the back or side panel, or inside the appliance. Parts that look identical often differ by model, so match the number to the listing before you order.
