Goodman GKS90904CXAA Control Board
The control board is designed to oversee everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. The HVAC system will be unable to run at all unless the control board is accurately installed and configured. You must do some research while selecting a replacement because of the wide variety of heating and cooling systems. The control board picked will need to be a match with your existing board and be compatible with the brand and the model of furnace or air handler you have.
Indications your primary control board is in dire straights
- System has a type of code shown on the front of the control board
- The whole unit ceases to go correctly
- Power to the control board has to be turned off and back on often for the system to continue working
