After 44 years of electrical work I was aware of the electronic of appliances. I evaluated this problem had to be a OL or Limit control. After taking the front of the dryer off and finding where the heat elements were located I followed the factory's circuit schematics. I used my ohm meter to check for continuity. I then removed the parts and went on line to find Appliance Parts Pros.com. Out of several web sites this one seemed to be the best. I found the parts I needed and ordered them with a visual match on line. In this case part numbers didn't match. The visual aid helped. Received with in a few days. I put everything back together in a little over an hour. The results of my due diligence I saved more than a couple hundred dollars for non warranty parts and service.
Thanks to Appliance Parts Pros.com.
