Carrier FB4CNF036 Control Board
The Carrier FB4CNF036 control board is created to regulate everything including the gas valve, the ignition igniter, all the sensors and the blower all together. It is impossible for your furnace or air handler to even run at all without the main control board configured and seated properly. You must be careful when you decide to replace your control board because of the many variances of models within certain brands. The chosen circuit board will need to be a match with your existing board and be compatible with both the make and model of your Carrier FB4CNF036 unit.
Clues of a weakening main circuit board
- The AC or furnace is not able to function correctly
- There is a strange code being shown on the circuit board
- The system board has to be powered down and back up many times a day for it to run correctly
