OEM Carrier Gas Valve EF680015 for Model YAC42110YAC202AK

This is the factory OEM replacement gas valve (part number EF680015) for the Carrier YAC42110YAC202AK. The combination gas valve is the core component responsible for regulating and delivering the precise flow of gas to the burners during each heating cycle. When this valve fails, the unit will typically lock out after repeated failed ignition attempts, produce no heat despite the inducer running, or trigger a fault code indicating no gas pressure or flow. A failed gas valve must be replaced promptly — it is not a serviceable component.
