OEM Lennox Gas Valve — 47K24

The genuine OEM Lennox 47K24 gas valve is the heart of your furnace's combustion system, precisely controlling the flow of natural gas or propane to the burners. Working in concert with the ignition control and safety circuit, it opens on a call for heat and shuts off instantly when the cycle ends — regulating fuel pressure to deliver clean, efficient, and safe combustion in your Lennox furnace.

Warning signs of a failing gas valve include the furnace not igniting or producing no heat, burners that light weakly or inconsistently, a clicking valve that won't open, or a system that locks out on a safety fault. Because a malfunctioning gas valve is a safety concern, any gas smell or repeated ignition failure should be addressed promptly.

Using the OEM Lennox 47K24 is essential for gas-fired equipment. This valve is matched to your furnace's specific pressure ratings, connection sizes, and control voltage. Aftermarket valves risk incorrect gas pressure, poor fitment, and compromised safety interlocks. The factory part guarantees correct calibration, proper fit, and safe, reliable heating for your Lennox system. Professional installation by a licensed technician is strongly recommended.
