OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024045ABJA

This is the factory-specified OEM gas valve kit (part number EF660015) for the Carrier GB1AAV024045ABJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates and controls the flow of gas to the burners in response to signals from the ignition control board. When the gas valve fails, your furnace will attempt ignition but produce no flame, resulting in a lockout fault code, cold air blowing, or a complete no-heat condition. A faulty valve may also cause intermittent heating, gas odor near the unit, or failure to open on demand.

• Specs: OEM combination gas valve kit | Part No. EF660015 | Factory-matched inlet/outlet sizing | Includes valve body and required installation hardware | 24V coil operation for compatibility with standard IFC control boards
• OEM vs Generic: This is a genuine Carrier OEM valve, calibrated to exact inlet pressure and flow specifications for the GB1AAV024045ABJA. Aftermarket valves often lack the precise pressure regulation required, risking improper combustion, nuisance lockouts, or unsafe gas delivery — always use OEM on gas-carrying components.
• Install Difficulty: 4/5 — Gas valve replacement involves working with live gas lines and should be performed by a licensed HVAC technician. Tools required: adjustable wrench, pipe thread sealant, manometer for gas pressure verification, screwdrivers, and a multimeter to verify 24V coil signal. Always shut off the gas supply and power to the unit before beginning work, and leak-test all connections after installation.
