OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV048091AEJA

This is the OEM factory-specified gas valve kit (part number EF660015) for the Carrier GB1AAV048091AEJA gas furnace. The combination gas valve is the heart of your furnace's fuel delivery system — it controls the flow of natural gas or propane from the supply line to the burner assembly under direct command from the integrated furnace control board. When the gas valve fails, the furnace will attempt ignition, the hot surface igniter will glow, but no flame will establish, resulting in a lockout fault code. Other symptoms include no heat with the inducer and igniter functioning normally, or an intermittent heating failure that worsens over time.

• Specs: OEM combination gas valve | Part No. EF660015 | Factory-rated inlet/outlet pressure | 24V coil actuation | Compatible with natural gas and LP configurations (verify rating on data plate)
• OEM vs Generic: This is a genuine OEM Carrier part engineered to exact factory tolerances for the GB1AAV048091AEJA. Generic valves may differ in pressure regulation, coil impedance, or port sizing — all of which can cause unsafe operation, nuisance lockouts, or code violations. OEM is always recommended for gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, depressurizing the line, disconnecting wiring harness connectors, and re-sealing all gas fittings with approved thread sealant. Tools needed: adjustable wrench, pipe wrench, manometer (to verify outlet pressure post-install), multimeter, and leak-detection solution. A licensed HVAC technician is strongly recommended for this repair.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
