Well, There doesn't seem to be much help here... I will go ahead nd answer my own question for future users:
The Thermal Cut off was bad. It's located on the Heating duct and when you replace it, it should be replaced with the Hi Limit Thermaostat. They come as a kit (part #: 279769). I guess most of these are accesable from the back through a panal, mine was through the fromt kick plate. I had to take a couple screws out of the supportting leg, but then, with a couple gentle twists, it came out. I then had to dissconnect one of the wires to the heating coil in order to get it out far enough to work on. You should check the heating coil with an ohm meter (should have resistance, if not it's bad). I found several of these kits online, but I got mine from a used appliance place for $15.
