OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024045ADJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB1AAV024045ADJA gas furnace. The gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of natural gas or propane from the supply line to the burners in direct response to signals from the control board. When the gas valve fails, the furnace will attempt ignition, the igniter will glow, but no flame will establish, resulting in repeated lockout cycles and a complete loss of heat. Common symptoms include error codes indicating failed ignition, the smell of gas without burner operation, or a valve that sticks open or closed.

• Install difficulty: 4/5 — Gas valve replacement involves working with live gas lines and should be performed by a licensed HVAC technician or gas fitter. Tools required: adjustable wrench, pipe thread sealant (gas-rated), manometer for gas pressure verification, and leak-detection solution.
