Carrier FX4BNF048000AAAA Control Board
The Carrier FX4BNF048000AAAA control board is constructed to oversee everything including the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. The HVAC system will be unable to operate whatsoever unless this important circuit board is configured and seated properly. You must be sure when you are choosing a replacement board because of the diversity of HVAC systems. A control board that you have chosen will have a matching part number that will fit in the brand and the model of your particular system.
Red flags of an inadequate main board
- There is lit up error code directly on the circuit board
- Entire unit declines to function at all
- Everything has to be powered down and back up often in order to operate

If you decide on picking up or purchasing do your best and cross-check the model number and also make a visual comparison in order to be sure the correct replacement control board is being ordered. If you are not sure about the properly replacing the new control board on your own then it is probably best to contact a professional to do the work for you.
