International Comfort Products GDL100N16A3 Control Board
The control board is made to oversee everything including the gas valve, the igniter, most sensors as well as the air circulator all together. Your furnace or AC will not be able to function without the control board in connected and operational. You must do some research when you are deciding on a replacement due to the vast differences in heating and cooling systems. The brand of board you choose will need to pair with the part number from both the brand and model of your heating and cooling system.
Signals your main board needs replacing ASAP
- Everything has to be powered down and back up many times a week for the furnace or AC to kick on
- Could be an some sort of code indicated directly on the board
- Air conditioning or heating system declines to work well
