Carrier FX4BNF042000 Control Board

The control board is constructed to control everything including the gas valve, the igniter, most sensors as well as the air circulator all in one unit. Heating and cooling systems will not even run at all without the board configured and seated properly. A control board that you have chosen will have a part number that will match both the brand and model of your Carrier FX4BNF042000 unit. It is of utmost importance when you decide to replace your control board due to the many differences between brands, models and types of systems.

What are some indications that my HVAC circuit board is about to stop working?
