The genuine OEM Lennox 98W07 gas valve regulates the flow of natural or LP gas to the burners in your Lennox furnace. Working in concert with the ignition control and safety circuit, it opens only when a call for heat is present and the safeties are satisfied, then meters gas at the correct manifold pressure for clean, efficient combustion.
Common failure symptoms: A failed gas valve typically results in no heat, burners that fail to ignite, or a furnace that locks out on ignition failure. You may also notice intermittent operation, a valve that clicks but does not open, delayed ignition, or the system short-cycling. Because it directly controls fuel delivery, a malfunctioning valve should always be replaced rather than repaired.
Why OEM matters: The Lennox 98W07 is calibrated to the exact pressure specifications, voltage, and connection layout your furnace requires. An aftermarket substitute risks improper gas pressure, combustion problems, and safety-lockout issues. Installing the factory valve ensures safe, reliable ignition and keeps your Lennox heating system operating to spec. This is a gas-carrying safety component — installation should be performed by a qualified HVAC technician with proper leak testing.
