OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV042091ABJA

This is the factory OEM gas valve kit (part number EF660015) for the Carrier GB1AAV042091ABJA 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, the furnace may attempt ignition and lock out, produce no heat at all, or trigger a fault code indicating no gas pressure or flow. Replacing the gas valve with an exact OEM unit restores proper pressure regulation, correct flow rates, and reliable ignition sequencing as designed by Carrier.

• Specs: OEM combination gas valve | Part No. EF660015 | Factory-matched inlet/outlet pressure ratings | 24V coil voltage | Compatible with natural gas configuration — verify LP conversion requirements separately
• OEM vs Generic: OEM gas valves are calibrated to exact manifold pressure specifications for the GB1AAV042091ABJA burner assembly. Aftermarket valves may have pressure tolerances that cause incomplete combustion, nuisance lockouts, or carbon monoxide risk — do not compromise on this safety-critical component.
• Install difficulty: 4/5 — Gas valve replacement must be performed by a licensed HVAC technician or qualified gas fitter. Tools required: adjustable wrench, pipe thread sealant, manometer for manifold pressure verification, and leak detection solution. Always shut off gas supply and disconnect power before beginning work.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier GB1AAV042091ABJA gas furnace. Verify your existing valve's part number and gas type (natural gas vs. LP) against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — order with confidence and get back to heat fast.
