OEM Carrier Gas Valve EF680015 for Model YAC48110YAC303AT

This is the factory OEM replacement gas valve (part number EF680015) designed specifically for the Carrier YAC48110YAC303AT packaged gas/electric unit. The combination gas valve is the critical component that controls the flow of gas to the burners during the heating cycle. When this valve fails, the unit will attempt ignition but receive no gas flow — resulting in a no-heat condition, repeated lockout errors, or a system that sparks but never establishes a flame. Replacing with the correct OEM valve ensures proper inlet/outlet pressure, staging operation, and safe shutoff performance.
