Carrier 48XZN030060300 Control Board
The entire heating and cooling system will not activate without the main control board installed as it should be according to the manufacturer. The Carrier 48XZN030060300 control board is created to command the gas valve, the ignition igniter, most sensors as well as the blower all at once. The board you select should be compatible with both the make and model of the unit in question. You must do some research when choosing a control board due to the vast differences in models and types.
Red flags to watch for in a failing primary control board
- Air conditioner or furnace refuses to work whatsoever
- There is some sort of code shown somewhere on the circuit board
- Power to the circuit board has to be reset a lot for the thermostat to kick in
