Carrier 58MCB040 Control Board
The Carrier 58MCB040 control board is created to direct the gas valve, the ignition igniter, the flame sensor as well as the blower all in one unit. The HVAC system will be unable to run without the control board installed as it should be according to the manufacturer. The board that you will choose must have a matching part number consistent with both the brand and model of air handler system you have. You must be sure upon choosing a board as a replacement due to the many differences between models and types.
Important clues of a defective main circuit board
- There is a fault code directly on the control board
- The HVAC system has to be reset more often than not for everything to run again
- Air conditioning or heating system ceases to go whatsoever
