Carrier 50HJQ012 Control Board
The entire heating and cooling system will not operate whatsoever lest the circuit board is installed as it should be according to the manufacturer. The control board is constructed to command the gas valve, the igniter, the flame sensor as well as the air circulator all at once. The board you choose should have part numbers that match the brand and the model of the system you have installed. You must do some research while searching to pick up a replacement control board because of the wide variety of brand and air handler types.
Important signs your control board will eventually need to be replaced
- System has an error code revealed somewhere on the circuit board
- The furnace or AC is not able to work whatsoever
- Everything has to be powered down and back up quite frequently for the system to operate once again
