Bought the dryer repair kit , new heater element and temperature sensor. During the replacement I found the heater element steel plate was over heated and cracked, one roller wheel was separated from the bearing, belt pully wheel was about to fail, belt was about to fail. Lots of the issues were due to excessive lint on everything - the wheels bearing surfaces were clogged with lint. I cleaned everything and replaced parts. sealed joint on the duct with foil sheet metal tape to reduce lint inside the dryer. works like new now - dried a full load of blue jeans on 40 minute cycle - it was taking 60 to 80 munutes before
