OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048090AAJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB1AAV048090AAJA gas furnace. The gas valve is the critical safety and flow-control component that regulates the supply of natural gas or propane to the burner assembly. When the valve fails, the furnace will attempt ignition but produce no flame, resulting in a lockout condition and no heat output. Common failure symptoms include the igniter glowing but burners not lighting, a fault code indicating gas valve failure, or the furnace cycling off immediately after the ignition sequence begins.
