Replaced existing items with the Thermal Cut-Off Kit and replaced the Heating Element. Biggest Problem was the Fastener (1) holding the Heating Element. It`s head was on the back side, out of site, close to dryer frame, near many sharp sheet metal edges (ouch & blood). So a metal shear and pliers made access for my Dremel to grind off the metal screw and the new Heating Element was replaced and held in place with a bolt, lock washer, nut combo. All Works..............def
