OEM Lennox Gas Valve — 57W06

The genuine OEM Lennox 57W06 gas valve is the heart of the fuel-delivery system in your Lennox furnace. Working with the ignition control and safety circuit, it regulates gas flow to the burners — opening on a call for heat, holding a stable pressure while the furnace fires, and closing completely to shut off fuel when the cycle ends. It is a precision-engineered component that directly affects both heating performance and combustion safety.

Common failure symptoms: The furnace fails to ignite, the igniter glows or sparks but no gas is delivered, burners light weakly or unevenly, or you hear clicking with no flame. A valve that leaks internally, sticks, or loses its solenoid can cause no-heat calls and, in some cases, unsafe gas conditions.

Why OEM matters: The Lennox 57W06 is calibrated to the correct manifold pressure, voltage, and pipe configuration your furnace was designed for. Aftermarket valves can misregulate gas flow, causing poor combustion or safety lockouts. Installing the factory-matched valve restores proper fuel control and protects the integrity of your Lennox equipment. Gas valve replacement should be performed by a licensed HVAC technician.
