Carrier 48GP048090300 Control Board
Heating and cooling systems will not even function lest the main control board is correctly installed. The control board is created to control the gas valve, the ignition igniter, the flame sensor as well as the blower all in one unit. Be very careful when you are deciding on a replacement because of the diversity of models and types. A matching board should have a replacement part number that matches both the brand and model of your particular system.
