Goodman GCVC90905DXAB Control Board
Your air handler will be unable to run at all without the board accurately installed and configured. The Goodman GCVC90905DXAB control board is designed to regulate everything including the gas valve, the ignition igniter, most sensors as well as the blower all at once. A matching board should have part numbers that match the brand and the model of the unit you have installed. You should always be careful when you are deciding on a replacement due to the vast differences in certain brands.
Chief elements of a poorly performing primary control board
- The AC or furnace cannot function well
- The whole system needs to be reset all the time for the system to continue working
- Could be an a flashing error code displayed somewhere on the board
