Frances E St Louis , MO December 07, 2014 Appliance: Model WHIRLPOOL DUET DRYER The auto dry was not working so the moisture sensor bar needed to be replaced I ordered 2 new moisture sensor bars and replaced them. There was a video on the web site that showed how to do it in a very simple way. Other videos had you take the whole dryer apart and that was not necessary.
