Goodman GKS90453BXAA Control Board
The control board is created to direct the gas valve, the igniter, all the various sensors and the blower all together. Heating and cooling systems will not even run at all lest this board is installed as it should be according to the manufacturer. A replacement board will need to pair with the part number from both the brand and model of your particular system. You must be sure while choosing a new control board because of the wide variety of models within certain brands.
Key indicators that my HVAC circuit board is about to go out?
- Heat or AC unit cannot work well
- Everything has to be powered down and back up more often than not for the heating or cooling to kick in
- There may be a flashing error code displayed on the control board
