OEM Lennox Gas Valve — 98M41

The genuine OEM Lennox 98M41 gas valve is the heart of your Lennox furnace's heating operation, precisely regulating the flow of natural gas to the burners. Controlled by the furnace's ignition system, it opens on a call for heat to deliver a metered gas supply for clean, efficient combustion, and closes completely when the cycle ends or a safety limit trips. It also holds the correct manifold pressure so the burners fire at the manufacturer's rated input.

Common failure symptoms: A failing gas valve is a leading cause of no-heat complaints. You may hear the igniter glow and the system attempt ignition, but the burners never light because the valve won't open. Other signs include short-cycling, weak or uneven flames from incorrect gas pressure, a clicking valve that fails to actuate, or a furnace that locks out after repeated failed ignition attempts.

Why OEM matters: A gas valve is a safety-critical component that must match your furnace's exact voltage, gas type, and pressure specifications. The OEM 98M41 is engineered to Lennox tolerances for correct manifold pressure, reliable shutoff, and seamless integration with your furnace's control board. For a component handling combustible gas, genuine OEM is the only responsible choice — installation should always be performed by a licensed HVAC technician.
