International Comfort Products NNE100F20A1 Control Board
Your furnace or AC will not activate without the control board installed as it should be according to the manufacturer. The control board is made to command the gas valve, the ignition igniter, most sensors as well as the air circulator all in one unit. You must do some research when you choose a replacement due to so many small differences in particular brands and their models. The board you choose is supposed to have a part number that matches both the brand and model of your heating and cooling system.
Clues to watch for to know your main board should be replaced
- Heat or AC unit is unable to start correctly
- The whole system needs to be reset repeatedly for everything to run again
- There is a certain error code directly somewhere on the circuit board
