The flame would ignite on the initial start and then would never re-ignite. I could see the ignitor glowing through the little peep hole but it would never flame up. So reading through other peoples posts I ordered 2 parts that were most likely faulty, the flame sensor and the gas valve coils along with a new ignitor since my dryer was on the old side figured it couldn't hurt. I watched the install videos so I could see how to get access to the parts and it seemed fairly easy. Within 10 minutes I had the dryer open and the parts installed. The long part was cleaning up all the lint build up inside the dryer. Put everything back together and worked as good as new.
