International Comfort Products NNE075F16A1 Control Board
The International Comfort Products NNE075F16A1 control board is made to direct everything including the gas valve, the igniter, the flame sensor as well as the blower all at once. Your air handler will be unable to operate whatsoever lest the circuit board is properly connected to the unit. It is of utmost importance when you are deciding on a replacement due to the vast differences in brands, models and types of systems. The brand of board you choose should have part numbers that match the brand and the model of furnace or air handler you have.
Indications to watch for in a failing main circuit board
- System has a numbered error code directly somewhere on the circuit board
- Your system will not do anything at all
- Power to the control board has to be powered down and back up often for it to work
