OEM Carrier Gas Valve Kit EF660015 for Model GB3AAV036075ABJA

This is the factory OEM replacement gas valve kit (part number EF660015) for the Carrier GB3AAV036075ABJA gas furnace. The combination gas valve is the critical component that controls gas flow from the supply line to the burner assembly. It responds to 24V signals from the control board to open during ignition and close when the call for heat ends. When this valve fails, common symptoms include a complete no-heat condition, the furnace locking out after multiple ignition attempts, or the burners failing to light even when the igniter glows normally. In some cases, a faulty valve may also cause weak or uneven flame across the burner manifold.

• OEM vs Generic: This OEM valve is manufactured to Carrier's precise pressure-regulation tolerances. Aftermarket valves may not match inlet pressure ratings or flow coefficients, risking incomplete combustion, nuisance lockouts, or unsafe operation — always use OEM on gas-carrying components.
