Goodman GSC140421A Control Board
The control board is designed to direct everything including the gas valve, the igniter, the flame sensor as well as the air circulator all in one unit. Your furnace or AC will not operate whatsoever without the control board correctly installed. Be absolutely sure when you are deciding on a replacement because of the many variances of HVAC systems. A replacement board will have to match part numbers both the make and model of furnace or air handler you have.
Clues of a dying primary control board
- System has an error code appearing somewhere on the board
- The HVAC system has to be turned off and back on rather frequently for it to run correctly
- System is unable to run well
