Carrier 50JZ042300 Control Board
The control board is made to oversee everything including the gas valve, the ignition igniter, most sensors as well as the blower all together. Heating and cooling systems will not even run lest the main control board is correctly installed. You should always be careful while searching to pick up a replacement control board because of the diversity of certain brands. The chosen circuit board should match both the brand and model of furnace or air handler you have.
Major warnings your control board needs to be replaced
- When turned on, there is lit up error code being shown somewhere on the circuit board
- Power to the circuit board has to be powered down and back up repeatedly for the system to operate once again
- Your HVAC unit does not work correctly
