OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048111AFJA

This OEM combination gas valve kit (part number EF660015) is the factory-specified replacement for the Carrier GB1AAV048111AFJA gas furnace. The combination gas valve is the critical component that regulates and delivers natural gas or propane to the burner assembly. When this valve fails, the furnace will attempt an ignition cycle but produce no flame — resulting in a lockout condition, error codes, or a complete loss of heat. Common failure symptoms include no gas flow to burners, a stuck-open or stuck-closed valve, inconsistent heating, or the control board flagging a gas valve fault.

• Specs: OEM combination gas valve | Part No. EF660015 | Factory-matched inlet/outlet connections | Compatible with natural gas and LP (verify unit configuration) | Meets all factory pressure and flow specifications
• OEM vs Generic: This is a genuine OEM Carrier part built to exact factory tolerances. Aftermarket gas valves can introduce pressure inconsistencies, improper shutoff timing, and may void equipment warranties — never compromise on a gas-carrying component.
• Install difficulty: 4/5 — Gas valve replacement involves shutting off the gas supply, relieving line pressure, disconnecting wiring harnesses, and verifying leak-free connections after installation. Tools needed: adjustable wrench, pipe thread sealant, manometer for gas pressure verification, and a combustible gas leak detector. This repair is recommended for licensed HVAC technicians only.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
