The genuine OEM Lennox 78L62 is a Honeywell VR8305Q-4161 LP (liquid propane) gas valve operating on 24V and rated for ambient temperatures from -40°F to 175°F. It controls the flow of propane to the burners in compatible Lennox furnaces, opening on a call for heat and closing to safely shut off fuel, serving as a core safety and combustion-control component in LP-fueled systems.

When this valve fails, common symptoms include no ignition, delayed or rough lighting, short cycling, an unstable or weak flame, or the furnace failing to produce heat while the blower still runs. A valve that clicks without opening — or one that will not fully close — indicates it is time for replacement.

Because it is configured specifically for LP/propane service, installing the OEM Lennox 78L62 valve is essential to maintain the correct manifold pressure and fuel calibration your equipment demands. Genuine Honeywell VR8305Q parts guarantee proper 24V operation, reliable combustion, and preservation of your Lennox system's safety certification — critical protections that generic replacements cannot ensure with propane fuel.
