International Comfort Products NAC248GKA1 Control Board
The International Comfort Products NAC248GKA1 control board is designed to command everything including the gas valve, the ignition igniter, most sensors as well as the air circulator all together. The HVAC system will be unable to be able to function unless this important circuit board is accurately installed and configured. It is imperative that you select wisely when you are choosing a replacement board due to variances between HVAC systems. The board that you will choose should be compatible with both the brand and model of the system you have installed.
Clues of an ailing main board
- There is lit up error code appearing on the circuit board
- The system board has to be reset a lot for everything to run again
- Your HVAC unit declines to initialize at all
