Carrier 58MVB120F10120 Control Board
The control board is designed to command the gas valve, the ignition igniter, the flame sensor and the blower all together. Your system definitely will not run without the main control board properly connected to the unit. A matching board should have a replacement part number that matches both the make and model of the unit in question. You must be sure upon picking a replacement board due to so many small differences in systems.
What warnings are present when my main circuit board has to be replaced?
- System is unwilling to work correctly
- When turned on, there is some sort of error code indicated directly on the front of the control board
- Power to the circuit board has to be turned off and back on rather frequently for it to run correctly
