The control board is made to command the gas valve, the igniter, all the sensors as well as the blower all in one unit. HVAC systems will not be able to function unless this board is accurately installed and configured. Be very careful upon choosing a board as a replacement due to variances between certain brands. The selected board will have to be compatible with the brand and the model of the system you have installed.
