Whirlpool Dryer Idler Arm Replacement

简介

Use this guide to replace the idler arm on your Whirlpool dryer.

The idler arm supports the idler pulley on the shaft mounted to the arm. This pulley provides tension to the drive belt by means of the idler arm spring.

If the idler pulley has failed, you may need to replace the idler pulley shaft, which is mounted on the idler arm. In this case, it's simpler to obtain the pre-assembled unit and replace both components at once. The failure of either component will result in the drum not spinning correctly or drive belt failure.

This guide will work for most Whirlpool dryers. This guide is written with a model WED87HED dryer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.
