Lennox 13ACX-018 Control Board
The control board is constructed to regulate everything including the gas valve, the ignition igniter, all the sensors and the blower all together. Most systems will not be able to function lest this board is configured and seated properly. You must be sure while choosing a new control board due to the many differences between models within certain brands. The board that you will choose will need to be a match with your existing board and be compatible with both the make and model of your heating and cooling system.
