OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV048115AFJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB3AAV048115AFJA gas furnace. The gas valve is the critical component that controls the flow of gas to the burners during each heating cycle. When it fails, the furnace may attempt ignition, the igniter glows, but no flame is established — resulting in a no-heat lockout condition. A faulty gas valve may also cause intermittent heating, low flame output, or a complete failure to open, leaving your system dead in cold weather.
