International Comfort Products PGMD36H060A Control Board
The control board is designed to control everything including the gas valve, the igniter, all the various sensors and the blower all in one unit. The HVAC system will be unable to operate whatsoever unless the control board is in place and connected. It is imperative that you select wisely while selecting a replacement due to so many small differences in heating and cooling systems. The brand of board you choose is supposed to have a part number that matches both the make and model of the unit you have installed.
