Lennox Y5352 Lennox 550002283 Flame Sensor Kit for GWM Series Wall Mounted Gas Boilers OEM Replacement HVAC Boiler Ignition Sensor
Product Overview
The Lennox Y5352 Flame Sensor Kit 550002283 is a genuine OEM ignition sensor designed specifically for Lennox GWM Series wall mounted gas boilers. This flame sensor plays a critical safety role by detecting burner flame presence and confirming proper ignition during the heating cycle. If flame is not detected, the control board will shut down the gas valve to prevent unsafe operation.
Over time, flame sensors can accumulate oxidation or fail, leading to intermittent ignition, short cycling, or boiler lockouts. Replacing the flame sensor with the correct OEM Lennox part restores reliable burner operation and ensures safe, consistent heating performance.
This factory original Lennox flame sensor kit is engineered for direct fit installation and dependable flame rectification in compatible GWM gas boiler models. Ideal for HVAC technicians, boiler service professionals, and property maintenance applications.
