Carrier 58STA070 Control Board
The control board is constructed to regulate everything including the gas valve, the igniter, the flame sensor as well as the air circulator all together. Most systems will not function lest the main control board is in place and connected. The chosen circuit board will have a matching part number that will fit in both the brand and model of the unit you have installed. You must do some research when you decide to replace your control board due to differences in brand and air handler types.
Major warnings of a defective main circuit board
- The AC or furnace is unwilling to initialize at all
- Power to the circuit board has to be turned off and back on a lot in order to continue running
- There seems to be an error code displayed on the circuit board
