Heating and cooling systems will not even run lest this board is configured and seated properly. The control board is created to command the gas valve, the ignition igniter, all the sensors as well as the air circulator all together. Any control board you choose is supposed to have a part number that matches both the brand and specific model of the system you have installed. It is imperative that you select wisely while searching to pick up a replacement control board due to the many differences between models within certain brands.
