Carrier 50JZ030310 Control Board
The Carrier 50JZ030310 control board is made to regulate everything including the gas valve, the igniter, all the sensors as well as the blower all at once. Your system definitely will not run without the board in connected and operational. You should always be careful while picking a new replacement board because of the wide variety of systems. The brand of board you choose must be compatible with the brand and the model of the unit in question.
Simple signals your primary control board is failing
- The heating and cooling system does not run at all
- Power to the circuit board needs to be reset repeatedly for the furnace or AC to kick on
- There seems to be some sort of error code lit up on the control board
