Well, it's AMFONE to the rescue again! Thank you, thank you, thank you !!!

Several of the articles referenced a thermal fuse, and described it. So I started hunting around inside of the unit on the exhaust output, and THERE IT WAS ! Tested open with a meter, so I hooked a clip lead across the device and - voila - all worked as expected.
So, it's off to "Sears Parts Direct", which does indeed have the part in stock. I'll be picking up the replacement tomorrow.
I never could find a service manual, but this problem was fairly straight-forward, once I knew about the existence of the part and what it does.
Thanks again - truly appreciate the help !!!! Steve
