International Comfort Products NNE075B12A1 Control Board
The entire heating and cooling system will not activate lest the main control board is in place and connected. The International Comfort Products NNE075B12A1 control board is created to command everything including the gas valve, the ignition igniter, the flame sensor as well as the blower all in one unit. It is of utmost importance upon choosing a board as a replacement due to the many differences between brand and air handler types. The chosen circuit board will need to be a match with your existing board and be compatible with both the brand and specific model of air handler system you have.
Major warnings of a poorly performing main circuit board
- Your HVAC unit declines to work at all
- When turned on, there is a fault code instantly appearing on the front of the control board
- The system board has to be reset many times a day for the thermostat to kick in
