OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV048115ACJA

This is the factory OEM gas valve kit (part number EF660015) designed as the direct replacement for the Carrier GB3AAV048115ACJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of natural gas or propane from the supply line to the burner assembly in response to commands from the ignition control board. When the gas valve fails, the furnace will attempt ignition, the igniter will glow, but no flame will establish, resulting in a lockout fault code and a complete loss of heat.
