Description
When your furnace relies on clean, safe ignition and stable flame detection, the York S1 025 37499 000 Flame Sensor delivers dependable, OEM grade performance. This essential safety component ensures that a stable flame is present before gas continues flowing — helping prevent unsafe combustion or gas leaks.
