Took the Thermo cover off, looks like new. I observed the top switch making contact/ or not, moving it back and forth. Looked like the 'copper strip (tab) to make on/ off contact was too close, touching...making contact..IN THE OFF position.....thereby telling the furnace fan to remain on. I slightly ( very ) bent it out, and the system works perfect in the 3 cycles I ran it through. Simple fix for a simple old fashion switch mechanism.
