Carrier 50JZ036300 Control Board
The Carrier 50JZ036300 control board is created to control everything including the gas valve, the igniter, all the various sensors as well as the blower all in one unit. Most systems will not operate whatsoever without the main control board installed as it should be according to the manufacturer. The board you select must be compatible with both the brand and model of your heating and cooling system. You must do some research when you choose a replacement due to so many small differences in models and types.
General indicators that your control board has very little life left
- There seems to be a strange type of error code directly on the board
- Power to the control board has to be turned off and back on rather frequently for the furnace or AC to kick on
- The AC or furnace declines to work period
