The Thermal cut-off kit did the trick when my dryer would turn off after about 2 minutes. Took about 10 minutes to cool down before I could turn it on again. The same thing happened 2 more times. The dryer would run on a low heat setting and it took most of the day to dry 2 loads. I purchased from APP in the past so I checked their online videos and ordered the parts. I was impressed at the speed of delivery. It was like overnight. The repair was simple but not quite as easy as depicted. My Duet set sits on pedestals so the bottom cover was easy. The inside was like in the video but cramped could only use a rachet on the bottom screws of the sensor and cut it off. Used a tiny 1/4 wrench, working blind, and could only do a quarter turn at a time. Took a while but got it done now my 13 yr old wed915owwo works like new.
