International Comfort Products GDJ100M12C2 Control Board
Most systems will not operate without the control board installed as it should be according to the manufacturer. The International Comfort Products GDJ100M12C2 control board is designed to operate the gas valve, the ignition igniter, all the sensors as well as the blower all together. The board you choose must be compatible with the brand and the model of furnace or air handler you have. You must do some research while searching to pick up a replacement control board due to so many small differences in HVAC systems.
Simple signals your primary control board is going out
- When turned on, there is an error code displayed somewhere on the board
- The system board has to be powered down and back up quite frequently for it to run correctly
- AC or heating system is unwilling to start properly
