I figured that the problem had to do with the control panel and found appliancepartspros.com through in internet search - and am I glad I found them! The part was easy to locate via the model number and the part screen had a wealth of information including a schematic and a video showing how to remove and replace the part.
I ordered the part and received it in a very timely manner as they indicated on the website.
When I ran into some difficulty and had some questions, I contacted them via their on line chat. Their most helpful representative took the time to answer all of my questions and concerns. I put in the new part and the dryer is now working as it should.
The price of the part was reasonable but the service was priceless!
