Carrier 50SX042300 Control Board
HVAC systems will not run at all lest the circuit board is installed as it should be according to the manufacturer. The Carrier 50SX042300 control board is constructed to regulate the gas valve, the ignition igniter, all the sensors as well as the air circulator all in one unit. It is imperative that you select wisely when choosing a control board because of the diversity of heating and cooling systems. The board you select must have a matching part number consistent with both the brand and specific model of the system you have installed.
Major symptoms your Carrier control board needs replacing
- The whole system has to be reset more often than not for it to run
- There seems to be a fault code shown on the front of the control board
- Heat or AC unit is unwilling to start at all
