International Comfort Products GDJ100M12A1 Control Board
The control board is created to direct everything including the gas valve, the igniter, most sensors as well as the air circulator all together. Your furnace or AC will not function unless this important circuit board is correctly installed. The control board you choose is supposed to have a part number that matches both the brand and model of furnace or air handler you have. You must be careful when you decide to replace your control board due to the many differences between models and types.
How can I tell if my control board has a need to be replaced?
- The system board needs to be reset habitually for the furnace or AC to kick on
- The heating and cooling system refuses to initialize at all
- System has lit up error code directly somewhere on the circuit board
