Carrier 24ABA336A0030010 Control Board
The control board is designed to control everything including the gas valve, the igniter, all the sensors as well as the air circulator all at once. It is impossible for your furnace or air handler to even activate without the board in place and connected. You must do some research while choosing a new control board because of the diversity of heating and cooling systems. The correct control board will have a part number that will match both the brand and model of the unit in question.
