Carrier 50XL-A42 Control Board
HVAC systems will not run unless the control board is hooked up and is correctly configured. The Carrier 50XL-A42 control board is constructed to operate everything including the gas valve, the ignition igniter, most sensors as well as the blower all together. You must do some research when you are deciding on a replacement due to the vast differences in HVAC systems. A replacement board must have a matching part number consistent with the brand and the model of the unit in question.
What red flags are there that my main board is in need of replacing?
- AC or heating system ceases to start period
- The entire system has to be reset many times a week for it to run
- There seems to be flashing code shown directly somewhere on the circuit board
