Frigidaire FRP77PTT2R0 Control Board
Heating and cooling systems will not even function unless this board is configured and seated properly. The control board is made to control everything including the gas valve, the igniter, all the sensors as well as the air circulator all in one unit. The correct control board will have a part number that will match the brand and the model of furnace or air handler you have. It is of utmost importance while selecting a replacement because of the wide variety of systems.
