How did you check the power to both? with a volt meter and to ground?. Sounds like the neutral from them may be loose/disconnected and that may not have anything to do with the board.

I have both hooked to separate plug since outlet on furnace does not have power running through it? and no luck!

Sounds like you need an electrician or tech to check the wiring.
