well...I've been through the darn furnace and cleaned and checked everything. Grounds are good also. I'm leaning towards the control board going south as mention of the polarity issue got me pointed at bad grounds. Found another mention about polarity that was solved replacing the board.
The trick now, is finding the right control board. Apparently, there is a newer one out as mine isn't around any longer. I call my local HVAC suppliers and get the cold shoulder. They claim only a licensed tech in the industry can buy from them. I also need the actual model # of the board. I found a place online that can help, but without the Product or serial number, they're blind. I gave them the make and model with no luck.
I also set an appointment with a heating company, but they can't show until this coming Saturday. I'm going to cancel them and just get the info on the board and order from the online source.
The furnace is spic and span though. I got a lot of dust out of it. Should be an easy job replacing the board, that is, if I can find one.
Thanks for the tips, info and suggestions guys.
Kevin
