OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048091ABJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB1AAV048091ABJA gas furnace. The combination gas valve is the critical component that controls the flow of gas from your supply line to the burners. It opens on command from the control board when all safety conditions — including pressure switch closure and igniter warm-up — are confirmed. When this valve fails, the furnace will cycle through ignition attempts but produce no heat, often resulting in a lockout fault code. You may also notice a gas odor with no ignition, or the furnace simply refusing to fire at all.

• Specs: OEM combination gas valve kit | Factory-matched inlet/outlet sizing | 24V coil voltage | Includes mounting hardware and fittings as kitted by Carrier | Part# EF660015
• OEM vs Generic: OEM gas valves are factory-calibrated to the exact manifold pressure specifications for the GB1AAV048091ABJA. Aftermarket valves often require field adjustment and may not meet original pressure tolerances, risking improper combustion or nuisance lockouts.
• Install difficulty: 4/5 — Gas valve replacement involves working with natural gas or propane lines. This repair should be performed by a licensed HVAC technician. Tools required: manifold pressure gauge, adjustable wrench, pipe thread sealant, leak detection solution, and a multimeter to verify 24V coil operation before installation.
• 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.
