OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024045AFJA

This is the genuine OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV024045AFJA gas furnace. The combination gas valve is the critical component that regulates the flow of gas to the burners during the heating cycle. When it fails, symptoms typically include a complete loss of heat, the burners failing to light after a successful ignition attempt, or the furnace entering a hard lockout fault code. A faulty gas valve may also cause erratic flame behavior, delayed ignition, or the inducer running continuously without progressing to the heating stage.
