International Comfort Products GDJ075M12A1 Control Board
Heating and cooling systems will not even run at all without the control board accurately installed and configured. The control board is made to command everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. The board that you will choose must have a matching part number consistent with both the make and model of your particular system. You must do some research when choosing a control board due to variances between certain brands.
Clues to watch for to know your primary control board will need to be replaced
- The heating and cooling system is not able to initialize whatsoever
- Power to the circuit board has to be turned off and back on quite a lot for it to run correctly
- There may be a strange code indicated somewhere on the circuit board
