Carrier 58MXB120F10120 Control Board
The HVAC system will be unable to run lest the main control board is installed. The control board is made to regulate the gas valve, the igniter, most sensors as well as the blower all at once. You should always be careful when you are choosing a replacement board due to the vast differences in brand and air handler types. The proper control board should match the model number with both the make and model of your particular system.
Chief elements of a declining main board
- When turned on, there is a fault code directly on the control board
- AC unit or heating unit cannot run well
- The board needs to be reset quite frequently for the system to continue working
