OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV036070AFJA

This is the OEM factory-specified gas valve kit (part number EF660015) for the Carrier GB3AAV036070AFJA gas furnace. The combination gas valve is the critical component that controls the flow of natural gas or propane to the burner assembly. It receives a 24V signal from the control board and opens in sequence with the igniter and flame sensor to deliver a safe, controlled flame. When the gas valve fails, symptoms include a complete loss of heat, the furnace going through ignition attempts without lighting, repeated lockout codes, or audible clicking with no burner flame present.

• OEM vs Generic: This is a genuine OEM Carrier part, ensuring exact coil resistance, valve seat tolerances, and pressure regulation that generic aftermarket valves cannot consistently replicate. Using an OEM valve protects your heat exchanger and maintains manufacturer safety certifications.
• Install difficulty: 4/5 — Gas valve replacement involves working with live gas lines. Always shut off the gas supply at the service valve before beginning.

We strongly recommend a licensed HVAC technician perform this repair.
