Carrier 48CE Control Board
The control board is made to regulate everything including the gas valve, the ignition igniter, all the various sensors and the blower all in one unit. Your furnace or AC will not be able to function lest the main control board is correctly installed. The correct control board will need to be a match with your existing board and be compatible with both the brand and model of the system you have installed. Be absolutely sure while picking a new replacement board due to so many small differences in brand and air handler types.
Important clues of a barely functioning main board
- When turned on, there is a flashing error code indicated directly somewhere on the board
- The AC or furnace cannot initialize correctly
- The entire system needs to be reset quite a lot in order to operate
