OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV036070AFJA

This is the factory OEM gas valve kit (part number EF660015) designed as a direct replacement for the Carrier GB1AAV036070AFJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it controls the flow of gas to the burners in response to signals from the ignition control board. When this valve fails, common symptoms include a complete no-heat condition, the furnace going into ignition lockout after repeated failed start attempts, or a fault code indicating no gas pressure detected despite gas supply being confirmed at the meter. A faulty valve may also cause delayed ignition, weak flame, or intermittent heating that leaves your home cold on the coldest nights.

• Specs: OEM combination gas valve | Part No. EF660015 | Factory-matched inlet/outlet pipe size and manifold pressure | 24V coil actuation | Designed for natural gas or LP conversion per original unit configuration
• OEM vs Generic: OEM gas valves from Carrier are manufactured to exact pressure-regulation and flow specifications. Generic aftermarket valves may not regulate manifold pressure precisely, leading to unsafe flame conditions, nuisance lockouts, or voided equipment warranties — always use OEM on gas-side components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the manual gas supply, relieving line pressure, and disconnecting wiring harness and gas fittings. Tools needed: adjustable wrench, pipe thread sealant (approved for gas), multimeter, manometer for manifold pressure verification. This repair should be performed by a licensed HVAC technician in most jurisdictions.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day when placed before 3 PM local time.

Compatibility: This OEM gas valve kit is specifically matched to the Carrier GB1AAV036070AFJA gas furnace.

If you have any questions about fitment, our HVAC parts specialists will confirm compatibility before your order ships — no guesswork, no returns.
