Carrier 48XZN042090300 Control Board
The control board is made to direct everything including the gas valve, the ignition igniter, most sensors as well as the blower all together. The system will cease to operate whatsoever without the control board in its proper place and configured for your unit. The board that you will choose will need to be a match with your existing board and be compatible with both the brand and model of the unit you have installed. You must be careful while selecting a replacement due to so many small differences in systems.
What are the indications that my control board is almost dead?
- The furnace or AC will not initialize whatsoever
- Power to the circuit board has to be reset rather frequently in order to continue running
- There may be numbered code being displayed on the front of the control board
