Carrier 58MCA Control Board
The Carrier 58MCA control board is designed to control the gas valve, the ignition igniter, all the sensors as well as the air circulator all together. The entire heating and cooling system will not run at all unless this important circuit board is in place and connected. The control board picked is supposed to have a part number that matches both the make and model of your heating and cooling system. You should always be careful while selecting a replacement because of the wide variety of models and types.
What are some indications that my control board really needs to be replaced?
- The unit refuses to run well
- The entire system needs to be reset more often than not in order to continue running
- There is some sort of code suddenly appearing somewhere on the board
