International Comfort Products N2A348GKA200 Control Board
The control board is made to regulate the gas valve, the ignition igniter, the flame sensor and the blower all at once. Your furnace or AC will not operate unless the control board is installed. The proper control board must be compatible with both the make and model of air handler system you have. Be absolutely sure when you are deciding on a replacement because of the wide variety of brand and air handler types.
Important clues of a weak primary control board
- There is flashing code revealed somewhere on the board
- The power to the system has to be reset frequently for it to kick in
- Air conditioner or furnace is unable to run well
