Goodman ACVC90905DXAA Control Board
The Goodman ACVC90905DXAA control board is made to oversee everything including the gas valve, the ignition igniter, all the various sensors and the blower all in one unit. The system will cease to operate whatsoever without the control board hooked up and is correctly configured. The board you choose must have a matching part number consistent with both the make and model of the unit you have installed. You must be careful when you are deciding on a replacement due to variances between certain brands.
Chief elements of a defective Goodman control board
- The system has to be powered down and back up quite frequently for it to work
- Your HVAC unit refuses to work well
- System has flashing code directly somewhere on the circuit board
