Bradford G Leominster , MA January 02, 2016 Appliance: Model WHIRLPOOL DUET DRYER Clothes were not dry at end of cycle I followed the directions on the video. My wife said that the problem went away after it was installed It cost $15.00 for the part and 10 minutes of my time. I think I saved a service fee and retail cost for the part!
