Whynter ARC-14SH Control Board
Your system definitely will not activate unless this board is installed. The control board is designed to oversee everything including the gas valve, the igniter, most sensors and the blower all at once. It is imperative that you select wisely upon choosing a board as a replacement due to the vast differences in certain brands. Any control board you choose should have part numbers that match the brand and the model of the system you have installed.
Clues your control board needs replacing
- The whole system has to be powered down and back up many times a day for the heating or cooling to kick in
- When turned on, there is numbered code instantly appearing on the control board
- The AC or furnace cannot do anything properly
