Most systems will not be able to function lest the circuit board is installed as it should be according to the manufacturer. The International Comfort Products CXA236AKA1 control board is constructed to operate everything including the gas valve, the igniter, most sensors as well as the blower all at once. You must do some research when you are choosing a replacement board because of the diversity of models and types. The brand of board you choose will have to match part numbers the brand and the model of the unit you have installed.
