Goodman GKS90703BXAD Control Board
The Goodman GKS90703BXAD control board is designed to operate the gas valve, the ignition igniter, all the various sensors as well as the blower all in one unit. The entire heating and cooling system will not operate whatsoever lest this board is installed. Be very careful when you choose a control board due to so many small differences in systems. A matching board will have a matching part number that will fit in the brand and the model of furnace or air handler you have.
Chief elements to watch for in a bad primary control board
- Power to the circuit board needs to be reset rather frequently for the thermostat to kick in
- System has a fault code shown on the front of the control board
- Your system does not initialize at all
