Carrier 48GX030060300 Control Board
The Carrier 48GX030060300 control board is designed to regulate the gas valve, the igniter, most sensors and the blower all at once. Your furnace or AC will not run at all without the board accurately installed and configured. The selected board should match both the make and model of your Carrier 48GX030060300 unit. It is of utmost importance upon picking a replacement board due to so many small differences in heating and cooling systems.
Symptoms of a defective primary control board
- The entire system declines to work well
- There is flashing code shown directly on the board
- The HVAC system has to be reset a lot for the furnace or AC to kick on
