OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048135ADJA

This is the genuine OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV048135ADJA 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 integrated furnace control board. When the gas valve fails, the furnace will attempt ignition, the hot surface igniter will glow, but no flame will establish, resulting in a lockout condition and no heat. You may also see a diagnostic fault code indicating valve failure or a "no gas" condition.
