International Comfort Products HPFM48K000A Control Board
It is impossible for your furnace or air handler to even be able to function unless this board is correctly installed. The control board is created to command everything including the gas valve, the ignition igniter, all the various sensors and the blower all in one unit. A replacement board will have to match part numbers the brand and the model of air handler system you have. You must do some research when you choose a control board due to the many differences between brands, models and types of systems.
