Intermittent failures can be the board. A bad solder joint for example.
My furnace quit last fall, right near the end of our season. Checked everything and finally decided it was the circuit board, which would require pulling the furnace out of the rig to replace. Took it to the dealer and let them do it, along with wheel bearing service. It was the board. They also have the facilities and equipment to bench test it before putting it back in the rig.
