Carrier 58MXB140F10120 Control Board
The control board is made to regulate the gas valve, the igniter, most sensors and the blower all in one unit. The system will cease to be able to function without the board correctly installed. You must do some research while choosing a new control board due to so many small differences in certain brands. The board you choose will have a matching part number that will fit in both the brand and model of HVAC system.
Some clues your main board will need to be replaced
- AC or heating system does not operate correctly
- Power to the control board has to be powered down and back up often for it to kick in
- There may be a certain error code suddenly appearing somewhere on the board
