Replaced thermal cut off thermostat items in kitts at service and delivery. Good video. I also need a multimeter to check for continuity to find bad parts. $34 at Lowes. Still cheaper to do it my self. Also took off lint duct and cleaned it and also bent line to outside. Both had lot of lint and other debris. Remember to order the 2 new seals to replace. After cleaning the lint cover on machine I put nut driver down on top of dryer. It rolled and fell into lint screen hole. Only when to get it was to remove cover again. Don't recommend this.
