OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV042091ACJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB1AAV042091ACJA gas furnace. The gas valve is the critical component that controls the flow of gas to the burners — receiving a 24V signal from the control board and opening to allow combustion. When this valve fails, the furnace will attempt ignition but no gas will flow, resulting in a lockout condition and a complete loss of heat. Common symptoms include repeated ignition attempts with no flame, fault codes indicating gas valve failure, or a furnace that powers on but produces no heat.
