Carrier 38YKC048 Control Board
The entire heating and cooling system will not operate lest this board is properly connected to the unit. The control board is created to operate the gas valve, the ignition igniter, the flame sensor as well as the air circulator all in one unit. A control board that you have chosen should be compatible with the brand and the model of your Carrier 38YKC048 unit. Be very careful when you decide to replace your control board due to the vast differences in systems.
