Description
Ensure safe and reliable furnace operation with the York S1 025 35354 000 Flame Sensor, a genuine OEM part engineered to monitor burner ignition and maintain combustion safety. This critical component detects the presence of flame inside the combustion chamber — if flame is lost, the sensor signals the control board to shut off the gas valve, preventing gas leaks and unsafe operation.
