OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV024070ACJA

This is the factory OEM gas valve kit (part number EF660015) designed as the direct replacement for the Carrier GB3AAV024070ACJA gas furnace. The combination gas valve is the critical component that controls the flow of gas to the burners during the heating cycle. It receives a 24V signal from the control board and opens to allow gas flow upon a confirmed call for heat. When this valve fails, common symptoms include a complete loss of heat, the furnace entering repeated lockout cycles, error codes indicating no gas flow, or the burners failing to light even when ignition is confirmed. A faulty valve may also stick open — a serious safety concern requiring immediate replacement.
