The board is inexpensive, I keep a spare on hand since it fits so many of the furnaces I service. Before swapping boards, label any matching color wires with the corresponding terminal labels. Then take a bunch of pictures from multiple angles. Some older boards have some of the terminals in different positions than this replacement. Make sure that the wires go to matching terminals, not just matching locations on the new board. The thermostat terminals work better than the original, no need to hook the wires around the screw, they are secure under the square screw washer.
