International Comfort Products PGMD42G0606 Control Board
The control board is created to oversee everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all together. Heating and cooling systems will not even run at all without the board correctly installed. Any control board you choose should be compatible with both the brand and model of the system you have installed. You should always be careful when choosing a control board because of the wide variety of models and types.
