International Comfort Products NDN5100BHC2 Control Board
Your furnace or AC will not be able to function without the board in place and connected. The International Comfort Products NDN5100BHC2 control board is designed to command the gas valve, the ignition igniter, most sensors and the blower all at once. Be absolutely sure while searching to pick up a replacement control board due to differences in heating and cooling systems. The selected board should be compatible with both the brand and model of your particular system.
How do you know when your main board has to be replaced?
- Everything has to be powered down and back up many times a day for everything to run again
- Your system is unable to start well
- When turned on, there is flashing code shown directly on the circuit board
