Why Replace Your Flame Sensor?
Over time, flame sensors can accumulate oxidation and carbon buildup on the sensing rod, causing the furnace to misread or fail to detect the burner flame. This results in repeated ignition attempts, short cycling, or a complete furnace lockout. Replacing the flame sensor with a genuine York OEM part restores accurate flame signal readings and ensures safe, uninterrupted heating operation.
