OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV060115ACJA

This is the factory OEM combination gas valve kit (part number EF660015) designed as a direct replacement for the Carrier GB3AAV060115ACJA gas furnace. The gas valve is the critical component that controls the flow of natural gas or propane to the burner assembly. When it fails, the furnace will attempt ignition — the igniter will glow and the flame sensor may even prove a brief flame — but gas flow will be insufficient or completely absent, resulting in a no-heat lockout condition. Common failure symptoms include error codes indicating failed ignition attempts, a furnace that runs the inducer and igniter but never sustains a flame, or a complete absence of heat despite all other components functioning normally.

• Specs: OEM combination gas valve | Part No. EF660015 | Compatible with natural gas and LP (verify configuration) | Factory-calibrated pressure regulation | 24V coil actuation
• OEM vs Generic: This is a genuine Carrier OEM valve — factory-set to exact inlet/outlet pressure specifications for the GB3AAV060115ACJA. Aftermarket valves frequently ship with incorrect pressure regulation, creating unsafe operating conditions and voiding equipment warranties.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, relieving line pressure, and leak-testing all fittings after installation. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), leak detection solution, manometer for pressure verification. We strongly recommend a licensed HVAC technician perform this repair.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.
