OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV036070ADJA

This is the OEM factory-replacement gas valve kit (part number EF660015) for the Carrier GB3AAV036070ADJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it regulates the flow of gas from the supply line to the burners in response to signals from the ignition control board. When the gas valve fails, the furnace will attempt an ignition sequence but produce no heat, often triggering a fault lockout code. Common failure symptoms include no burner flame despite a functioning igniter and flame sensor, a furnace that short-cycles immediately after attempted ignition, or a gas valve that sticks open or closed.

• Specs: OEM combination gas valve | Factory-matched inlet/outlet pipe sizing | 24V coil operation | Designed for natural gas with LP conversion availability — verify your fuel type before ordering
• OEM vs Generic: The OEM EF660015 kit meets Carrier's exact flow rate, pressure regulation, and safety shutoff specifications. Aftermarket valves frequently deviate in pressure tolerances, risking improper combustion, nuisance lockouts, or unsafe operation. Always use OEM on gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, relieving line pressure, and leak-testing all connections after installation. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for gas pressure verification, and leak detection solution. This repair is recommended for licensed HVAC technicians only.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered specifically for the Carrier GB3AAV036070ADJA gas furnace. Always verify your existing valve's part number against EF660015 and confirm your fuel type (natural gas or LP) before ordering. If you have any fitment questions, our HVAC parts specialists are available to verify compatibility before you purchase — no guesswork required.
