Carrier 58DLX09010020 Control Board
The Carrier 58DLX09010020 control board is constructed to operate everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. Your air handler will be unable to operate lest the main control board is installed. The board that you will choose is supposed to have a part number that matches the brand and the model of furnace or air handler you have. Be absolutely sure when you choose a replacement due to the many differences between brand and air handler types.
Major indications your main board will not live much longer
- There seems to be flashing code indicated on the circuit board
- AC or heating system is not able to function at all
- The system board has to be powered down and back up quite often in order to run
