Carrier 50JX048300 Control Board
The Carrier 50JX048300 control board is designed to control everything including the gas valve, the ignition igniter, all the sensors and the blower all together. The entire heating and cooling system will not operate whatsoever unless this board is correctly installed. Be absolutely sure while searching to pick up a replacement control board due to the vast differences in particular brands and their models. The chosen circuit board will need to pair with the part number from both the brand and model of the unit in question.
How do you know if your main circuit board really needs to be replaced?
- The board needs to be reset rather frequently for it to work
- The whole unit declines to run at all
- Could be an a strange type of error code directly on the front of the control board
