I went online to your website and then talked with a rep. I figured I needed the sensing strips as my dryer was purchased in 2005. When I removed the top, I discovered that the belt around the tub was broken. I ordered the sensing switch, thermistor, sensing strips and the kit that included the belt and rollers. The most difficult and time consuming part of the repair was getting the new belt on the tension bar as it was such a tight spot and I did not have another person with an extra set of hands. Kudos to Matt on the video for making that part look so simple but then he has probably done it many times. With parts and expedited shipping, it was under $200, much less than a service call or new dryer. Thanks so much.
