Samsung AQB24J2WC Control Board
It is impossible for your furnace or air handler to even function unless the control board is in connected and operational. The control board is created to regulate everything including the gas valve, the ignition igniter, most sensors and the blower all together. You must be careful when you are choosing a replacement board because of the diversity of certain brands. A control board that you have chosen will have to be compatible with the brand and the model of the unit in question.
Important clues to watch for in a failing primary control board
- System has some sort of error code instantly appearing on the board
- Your system ceases to initialize well
- The entire system has to be powered down and back up quite frequently for everything to run again
