Good thoughts Brasstacks2, thanks.
It did exactly that. The Fan worked after reinstallation with the original Regulator and the light come on when **** is moved.
However the Recirculation selection does not appear to function, the light comes on when selected but the fan doesn't change speed. I didn't blow it out with cleaner, I will access it and do so.

Thanks for the PDF on the Board connectivity. Not Being familiar with it, I didn't realized they were hard connected and should come out together. When I removed the front of the unit, the two boards separated w/ease. I assumed they just "unplugged". I will take the controller back out and reconnect the boards with epoxy as you suggest.
