This actually happend late last winter and we "limped" through the rest of the cold days with a space heater. At one point I had a problem with it, and the insulation of the wire was probably chewed by a rodent so I removed that part and put a new end on that goes to the board. It worked fine for a few months now nothing. Basically the furnace goes through its sequence of events, you no longer hear the "ticking" of the igniter anymore.
My RV guy does not have the capability of testing the board so he suggested starting with the igniter.
Ideas?
