Application
This flame sensor is intended for use in Utica-Dunkirk gas-fired furnaces and boilers that require part number 550002284. Always verify compatibility with your specific model before installation. Refer to the equipment’s service manual for proper installation procedures and torque specifications.
Why Replace Your Flame Sensor?
Over time, flame sensors can accumulate oxidation or carbon deposits on the sensing rod, reducing their ability to pass the microamp signal required by the control board. Symptoms of a failing flame sensor include repeated ignition lockouts, short cycling, or a “no flame” fault code. Replacing the sensor with a genuine Utica-Dunkirk part restores proper system operation and helps avoid unnecessary service calls.
