Product review (5 stars): Perfect for my Whirlpool Duet WED9400
Parts fit perfectly on my Whirlpool Duet, an easy install. The main problem turned out to be the idler wheel which seems to be a common issue. Since I pulled the tub anyway I replaced the rollers and the belt. The entire job took only a few hours, and a lot of that time was used to vacuum the blower and the inside of the cabinet.
