OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV024050ACJA

This is the factory-specified OEM gas valve kit (part number EF660015) for the Carrier GB3AAV024050ACJA gas furnace. The combination gas valve is the critical control component that regulates gas flow from the supply line to the burner assembly. It receives a 24V signal from the control board and opens to allow gas to flow during a verified ignition sequence. When the gas valve fails, the furnace will complete its ignition attempt — inducer on, igniter glowing — but no gas will flow, resulting in a lockout condition and a no-heat call. Common symptoms include repeated ignition lockouts, error codes indicating flame failure, or a furnace that runs through the full startup sequence without ever producing a flame.
