International Comfort Products PGAD24D1K1 Control Board
The control board is designed to operate the gas valve, the ignition igniter, all the various sensors as well as the air circulator all at once. It is impossible for your furnace or air handler to even function without the control board configured and seated properly. The control board picked will have to match part numbers both the brand and specific model of the unit you have installed. You must do some research upon choosing a board as a replacement due to so many small differences in systems.
