OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048111AEJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV048111AEJA gas furnace. The combination gas valve is the critical component that controls the flow of gas from the supply line to the burner assembly. When it fails, the furnace will attempt ignition but produce no heat — the control board may log a lockout fault after multiple failed ignition cycles. Other symptoms include a furnace that runs the inducer and igniter but never fires, or intermittent heating followed by a no-heat condition.

• Specs: OEM combination gas valve | Factory-matched inlet/outlet sizing | 24V coil operation | Compatible with natural gas configurations — verify LP conversion requirements with your data plate
• OEM vs Generic: This is a genuine OEM Carrier part (EF660015), manufactured to exact factory specifications for pressure regulation, flow rate, and valve seat integrity. Aftermarket gas valves can have inconsistent pressure regulation, creating unsafe operating conditions or nuisance lockouts — always use OEM on gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, depressurizing the line, and leak-testing all connections after installation. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for outlet pressure verification, leak detection solution. We strongly recommend licensed HVAC technician installation for all gas valve replacements.
