OEM Lennox Gas Valve — 80M30

The genuine OEM Lennox 80M30 gas valve regulates and controls the flow of natural gas or propane to your furnace burners. Working in concert with the ignition control and safety circuit, it opens only when a call for heat and proof of ignition conditions are met, then delivers a precisely regulated pressure to ensure clean, efficient combustion. It is a direct factory replacement for the Lennox equipment it was originally installed in.

Symptoms of a faulty gas valve include a furnace that ignites but produces little or no heat, burners that fail to light, delayed ignition or a whoosh at startup, a clicking valve that won't open, or the smell of gas. Because the gas valve is a safety-critical component, intermittent operation should be addressed immediately.

Installing the OEM Lennox 80M30 guarantees the correct gas pressure regulation, electrical rating, and thread connections your furnace was engineered for. Aftermarket valves can deliver improper manifold pressure, causing sooting, short cycling, or unsafe operation. As a component that governs combustion safety, only a genuine OEM valve should be trusted — protecting both your equipment warranty and your home.
