Circuit board for repair of York and Colemean equipment. Replacing the circuit board is an easy do it yourself repair. We recommend leaving the wiring attached before removing the old board. Install new board and disconnect and reconnect any molex connectors. All individual wires should be moved one at a time and reconnected on the same designated terminal unless directed otherwise by an instruction sheet. We also recommend taking a digital picture of the old board before removal in case any wiring becomes accidentally disconnected during the repair process. If you are not sure which part is required contact us for help.
