Furnace Connections

I bought a replacement board last year but was unable to get furnace to work. I discovered the on/off rocker switch was shot when I accidentally shorted the board out. This was also due to having just enough knowledge to be dangerous while working on the furnace. I had the circuit soldered and then was not sure if I now had two good or two bad boards. Factor in the wiring problem dyslexia learning disability and a good measure of stupidity and frustration. Now you are starting to get the picture. If it wasn't for the fact that a neighbor tipped me off to this site when my Refer was only working on gas I'd still be scratching my as- on this one. Thanks again and again and again.
