Product review (5 stars): Fixed screeching sound from Whirlpool Duet dryer, model #WED94HEXW0
We have a Whirlpool Duet dryer model # WED94HEXW0 which started making an awful screeching sound as if the drum were scraping against metal. A quick online search told us this was likely related to the idler pulley, which we located and lubricated to solve the problem...for a week. The screeching started up again so we ordered some replacement parts from Amazon including this pulley and a "Whirlpool 4392067 Repair Kit for Dryer" as I wasn't sure which parts we needed. Turns out we only needed this pulley arm (though we kept the other parts for later) and it fit our dryer perfectly; the replacement of the pulley took about 2 minutes while the bulk of the work was removing and replacing the back panel of the dryer to get to the pulley. This part is not an official Whirlpool part but does the job. If you search for "whirlpool duet dryer pulley replacement" you can find some very helpful YouTube videos and instructions online. If a couple oafish DIY newbies like my husband and I can fix it, so can you!
