Description

Why Replace Your Flame Sensor?

Over time, flame sensors accumulate oxidation and residue on the sensing rod, reducing the microamp signal sent to the control board. When the signal drops below the control board’s threshold, the system shuts down as a safety precaution. Replacing the flame sensor with a genuine Utica-Dunkirk part restores full system performance and prevents unnecessary service calls.
