Carrier 48GX042060300 Control Board
Most systems will not operate lest this board is installed as it should be according to the manufacturer. The Carrier 48GX042060300 control board is designed to control everything including the gas valve, the igniter, all the various sensors as well as the blower all at once. It is of utmost importance while selecting a replacement because of the many variances of brands, models and types of systems. The chosen circuit board must be compatible with both the brand and specific model of your heating and cooling system.
