OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV036050AFJA

This is the factory OEM gas valve kit (part number EF660015) for the Carrier GB3AAV036050AFJA gas furnace. The combination gas valve is the central component that regulates the flow of gas to the burner assembly. It responds to 24V signals from the control board to open and allow ignition, then modulates or closes on demand. When this valve fails, the furnace will attempt ignition but produce no heat — you may see a fault code indicating no gas flow, failed ignition, or the system may lock out entirely after repeated unsuccessful ignition attempts.

• Specs: OEM combination gas valve | 24V coil input | Factory-calibrated inlet/outlet pressure settings | Direct drop-in replacement for EF660015 | Compatible with natural gas configurations (verify LP conversion if applicable)
• OEM vs Generic: This OEM valve is precision-calibrated to the exact inlet and outlet pressure specifications required by the Carrier GB3AAV036050AFJA. Aftermarket valves often ship with mismatched pressure ratings, risking incomplete combustion, lockout codes, or unsafe operation. OEM is always the recommended choice for gas-carrying components.
• Install Difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician. Required tools include a manometer for gas pressure verification, pipe wrench, leak-detection solution, and a multimeter to confirm 24V coil signal. Always shut off the gas supply and disconnect power before beginning work. Leak-test all fittings after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
