OEM Lennox Gas Valve Spring — 10M82

The genuine OEM Lennox 10M82 gas valve spring is a precision-calibrated component that controls the pressure regulation and return action within your Lennox gas valve. The spring sets the reference force the regulator diaphragm works against, helping maintain the correct manifold gas pressure and ensuring the valve seats properly when the burner cycles off. Because it directly influences gas flow and combustion, it is a critical safety and performance part.

Common failure symptoms of a weak, broken, or incorrect spring include improper manifold pressure, an under- or over-firing burner, delayed ignition, a valve that fails to fully shut off, or unstable flame. Any of these conditions can trigger lockouts or unsafe operation and warrant immediate attention.

Why OEM matters: Gas valve springs are matched to a specific spring rate that determines regulated outlet pressure. The OEM 10M82 delivers the exact calibration your Lennox valve was engineered for — an off-spec spring can shift manifold pressure outside safe limits and compromise combustion. Because this part governs gas flow, always use the factory-authorized component and have installation performed by a qualified HVAC technician to ensure safe, code-compliant operation.
