OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036045ADJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV036045ADJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of natural gas or propane from the supply line to the burners in response to signals from the control board. When the gas valve fails, the furnace will attempt ignition but produce no flame, resulting in a lockout condition and no heat. Common failure symptoms include a furnace that clicks or sparks but never lights, or one that powers on normally yet delivers only cold air.

• Specs: OEM combination gas valve kit | Factory-matched inlet/outlet sizing | 24V coil actuation | Compatible with natural gas and LP configurations per unit data plate — always verify gas type before ordering
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances for gas pressure regulation, seat sealing, and coil voltage. Aftermarket valves can exhibit improper shutoff pressures or coil failures, posing both performance and safety risks. OEM is strongly recommended for gas-carrying components.
• 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), manometer for pressure verification, leak detection solution. Professional installation is strongly recommended.
