Whirlpool WED87HED Dryer Idler Arm Replacement

Introdução

Use this guide to replace the idler arm on your Whirlpool Duet WED87HED 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.
