OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV060115ADJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB3AAV060115ADJA gas furnace. The combination gas valve is the critical component that controls the flow of gas to your furnace's burners. It receives a 24V signal from the control board and opens to allow gas flow during each heating cycle. When this valve fails, the most common symptoms include a complete no-heat condition, a furnace that attempts ignition but never fires, error codes indicating no gas pressure, or a unit that locks out after repeated failed ignition attempts. A faulty gas valve can also cause the furnace to run briefly before shutting down if the valve is slow to open or closes prematurely.
