OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036055AAJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV036055AAJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of gas to the burners in response to signals from the control board. When the valve fails, the furnace will attempt ignition but produce no flame, resulting in a lockout fault code. Other symptoms include no heat despite a functioning igniter and flame sensor, a stuck-open or stuck-closed valve, or audible gas control clicks with no burner response.
