The genuine OEM Lennox 72W35 gas valve manages the flow of fuel to your furnace burners, opening on a heat call and shutting off safely when the cycle ends. Built to Lennox's exact pressure regulation and electrical specifications, it delivers the precise, metered gas supply required for clean ignition and stable, efficient combustion.
Common signs of a failing gas valve include a furnace that fails to ignite, no heat when the thermostat calls, intermittent or short-cycling burners, delayed ignition, or repeated safety lockouts. A leaking or stuck valve can also keep the entire heating system from operating.
Because the gas valve is a safety-critical component, the OEM Lennox 72W35 is the right choice — it matches the inlet pressure, regulation, and control signals your Lennox furnace was designed around. Non-OEM valves risk improper combustion, nuisance faults, and safety hazards. Install the factory-original part for guaranteed fit, certified safety compliance, and long-term reliability.
