OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV048095ADJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB3AAV048095ADJA gas furnace. The gas valve is the critical component that controls the flow of gas to the burners during each heating cycle. When it fails, the furnace will typically attempt ignition, the hot surface igniter will glow, but no flame will establish — resulting in a lockout fault code and no heat. In some cases a failed gas valve may also cause delayed ignition, intermittent heating, or a complete no-heat condition even when all other components test as functional.
