Samsung AQB12JJWC Control Board
The Samsung AQB12JJWC control board is constructed to oversee everything including the gas valve, the ignition igniter, most sensors and the blower all at once. Your air handler will be unable to be able to function without this vital piece of hardware is installed as it should be according to the manufacturer. You should always be careful upon choosing a board as a replacement due to the vast differences in models within certain brands. A control board that you have chosen must be compatible with both the brand and specific model of your heating and cooling system.
Clues of a dying main circuit board

- When turned on, there is some sort of error code suddenly appearing on the board
