International Comfort Products NTC7075BFA3 Control Board
Heating and cooling systems will not even activate without the main control board installed as it should be according to the manufacturer. The control board is created to regulate everything including the gas valve, the ignition igniter, the flame sensor and the blower all together. Be very careful when choosing a control board because of the wide variety of particular brands and their models. The board you select will have a matching part number that will fit in both the brand and specific model of the unit in question.
Key clues of a bad main board
- When turned on, there is an error code indicated directly somewhere on the board
- The unit is not able to do anything period
- The board has to be powered down and back up quite often for the heating or cooling to kick in
