good afternoon.this is a common problem on these. you thermal fuse has blown. before replacing this clean your vent really good. usually when these go a clogged vent is the cause. (not always though) this is located on the blower assembly behind the panel under the door. heres a link to order it. http://www.repairclinic.com/PartDetail/Thermal-Fuse/3392519/2986?modelNumber=WED8300SW2
