Goodman ACVC90905DXAB Control Board
The system will cease to be able to function without the control board in its proper place and configured for your unit. The Goodman ACVC90905DXAB control board is designed to regulate everything including the gas valve, the igniter, all the various sensors as well as the air circulator all at once. The selected board should match both the brand and specific model of furnace or air handler you have. Be very careful when you choose a replacement because of the many variances of heating and cooling systems.
Major clues your primary control board needs a replacement ASAP
- The furnace or AC does not initialize whatsoever
- The control board has to be reset a lot for it to run
- There seems to be some sort of error code indicated on the front of the control board
