Goodman GCVC90905DXAA Control Board
HVAC systems will not operate without the main control board correctly installed. The Goodman GCVC90905DXAA control board is made to oversee everything including the gas valve, the ignition igniter, all the various sensors as well as the air circulator all together. The proper control board will have to match part numbers the brand and the model of furnace or air handler you have. Be absolutely sure while selecting a replacement due to the vast differences in systems.
Easy warnings of a deteriorating main circuit board
- There may be a numbered error code shown somewhere on the board
- The unit is unwilling to do anything period
- Power to the control board has to be reset often for the system to continue working
