OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036045AEJA

This is the factory OEM gas valve kit (part number EF660015) designed as the direct replacement for the Carrier GB1AAV036045AEJA gas furnace. The combination gas valve is the critical component that regulates natural gas or propane flow to the burners. It responds to 24V control signals from the furnace control board to open and close gas flow during each heating cycle. When this valve fails, common symptoms include a complete loss of heat, a furnace that attempts ignition but produces no flame, error codes indicating gas valve fault, or a burner that lights briefly then shuts down immediately.

• Specs: OEM part number EF660015 | Combination gas valve design | 24V coil operation | Factory-matched inlet/outlet sizing and pressure ratings for the GB1AAV036045AEJA | Compatible with natural gas and LP configurations (verify unit setup)
• OEM vs Generic: This is a genuine OEM Carrier gas valve kit — not an aftermarket substitute. OEM valves are pressure-tested and calibrated at the factory to meet precise flow rates and shut-off response times. Generic valves can introduce inconsistent gas pressure, nuisance lockouts, and in worst cases, unsafe operation. For a safety-critical component like a gas valve, OEM is always the recommended choice.
• Install difficulty: 4/5 — Gas valve replacement involves working with live gas lines and high-voltage components. Always shut off the gas supply and electrical disconnect before beginning work. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), multimeter, manometer (for outlet pressure verification post-install). A licensed HVAC technician is strongly recommended for this repair.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
