OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV042091AFJA

This is the factory-specified OEM gas valve kit (part number EF660015) for the Carrier GB1AAV042091AFJA gas furnace. The combination gas valve is the critical component that controls the flow of gas to the burners during each heating cycle. It receives a 24V signal from the control board and opens to allow gas flow once the igniter reaches operating temperature. When the valve fails, symptoms typically include a complete no-heat condition, repeated ignition lockouts, or a furnace that attempts to light but never sustains a flame — even when the igniter and flame sensor test correctly. A faulty gas valve can also cause delayed ignition, gas odor near the unit, or inconsistent burner operation.
