The control board is designed to command everything including the gas valve, the ignition igniter, the flame sensor and the blower all in one unit. Your air handler will be unable to activate unless this important circuit board is in its proper place and configured for your unit. The board you select should be compatible with the brand and the model of HVAC system. You must be sure upon choosing a board as a replacement because of the diversity of particular brands and their models.
