OEM Carrier Gas Valve Kit EF660015 for Model GB1AAV024065AFJA

This is the factory-specified OEM combination gas valve kit (part number EF660015) for the Carrier GB1AAV024065AFJA gas furnace. The combination gas valve controls the flow of gas to the burners, regulating pressure and acting as the final safety gate between the gas supply and the heat exchanger. When this valve fails, the furnace will complete its ignition sequence — inducer on, igniter glowing — but no flame will establish, resulting in repeated lockout codes and a cold home. Common failure symptoms include no heat, error codes indicating no gas flow, or a valve that opens but delivers insufficient gas pressure for reliable ignition.

• Specs: OEM combination gas valve | Part No. EF660015 | Factory-matched inlet/outlet pressure settings | 24V coil operation | Direct drop-in replacement for Carrier GB1AAV024065AFJA
• OEM vs Generic: OEM gas valves are factory-calibrated to exact inlet and manifold pressure specifications. Aftermarket valves frequently deviate in pressure regulation, risking nuisance lockouts, incomplete combustion, or unsafe operation — always use OEM on gas-carrying components.
• Install difficulty: 4/5 — Gas valve replacement requires shutting off the gas supply, depressurizing the line, and leak-testing all fittings after installation. Tools needed: adjustable wrench, pipe thread sealant (gas-rated), manometer for pressure verification, and a combustible gas leak detector. This repair is recommended for licensed HVAC technicians or experienced DIYers familiar with gas systems.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
