Carrier FY4ANF018000 Control Board
Your system definitely will not operate whatsoever unless this board is properly connected to the unit. The Carrier FY4ANF018000 control board is created to control everything including the gas valve, the ignition igniter, the flame sensor and the blower all at once. You must be careful while searching to pick up a replacement control board because of the many variances of models within certain brands. The brand of board you choose will have to be compatible with both the make and model of the system you have installed.
Cues of a poorly performing main circuit board
- There is a numbered error code revealed on the front of the control board
- System declines to operate correctly
- The HVAC system needs to be reset rather frequently for it to run correctly
