OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV048095AFJA

This is the factory-original replacement gas valve kit (OEM part number EF660015) for the Carrier GB3AAV048095AFJA gas furnace. The combination gas valve is the critical component that regulates the flow of natural gas or propane from the supply line to the burner assembly. When the valve fails, the furnace will complete the ignition sequence — inducer starts, igniter glows — but no flame is established, triggering a hard lockout. Common symptoms include a no-heat call, repeated ignition attempts with no burner flame, or fault codes indicating gas valve failure on the control board.

• Specs: Combination gas valve | Factory-matched inlet/outlet sizing | 24V coil operation | Compatible with natural gas and LP configurations per unit data plate | OEM part number EF660015
• OEM vs Generic: This is a genuine OEM Carrier gas valve kit, built to exact factory pressure regulation and flow specifications. Aftermarket valves may not meet the precise outlet pressure required for the GB3AAV048095AFJA heat exchanger, risking incomplete combustion, nuisance lockouts, or unsafe operation.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, relieving line pressure, and reconnecting gas fittings with approved thread sealant. Tools needed: adjustable wrench, 1/4" nut driver, manometer (for outlet pressure verification), and leak-detection solution. Gas work should be performed by a licensed HVAC technician. Always verify manifold pressure after installation.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.
