International Comfort Products PGAD30D1K4 Control Board
The control board is made to regulate the gas valve, the ignition igniter, the flame sensor as well as the blower all together. It is impossible for your furnace or air handler to even function without the board in connected and operational. The brand of board you choose must be compatible with the brand and the model of the unit you have installed. You should always be careful when you choose a replacement due to the many differences between models and types.
