International Comfort Products NDC7075BFA3 Control Board
The control board is designed to operate everything including the gas valve, the ignition igniter, most sensors as well as the blower all in one unit. Your furnace or AC will not activate unless this important circuit board is correctly installed. It is of utmost importance when you are deciding on a replacement due to the many differences between models within certain brands. The selected board should match the model number with both the make and model of your particular system.
What are some hints that my HVAC circuit board is about to go out?
- There is a strange type of error code being shown on the control board
- The power to the system has to be powered down and back up frequently for it to work
- The heating and cooling system is unwilling to initialize correctly
