Heat Controller VMH09SC-1 Control Board
The control board is created to direct the gas valve, the igniter, all the sensors and the blower all together. Your air handler will be unable to function lest this board is installed as it should be according to the manufacturer. You should always be careful when you are deciding on a replacement because of the wide variety of models within certain brands. The correct control board should match both the brand and specific model of air handler system you have.
