I went to the Appliance Parts Pros web sight and searched the trouble shooting section. It said a probable cause is the thermostat. This model has 3 thermostats, but they showed how to check them to see if they are functioning correctly. After checking all 3, I found 2 were working properly and 1 was not. From the diagram on the web sight it was difficult to determine which one I needed. I called customer service, and after a discussion with the very helpful lady, determined which one I needed and put it on order. Four days later I received the thermostat, installed it in 15 minutes, and the dryer now works perfectly !!! My wife thinks I am a genius !! Thank you Appliance Parts Pros for making me look smart and saving a lot of money !!
