Why Replace Your Flame Sensor?
Over time, flame sensors can accumulate oxidation or carbon buildup, leading to weak or failed flame signal readings. A compromised flame sensor may cause repeated ignition lockouts, short cycling, or complete system shutdown. Replacing the sensor kit with a genuine Laars part restores proper system function and helps extend equipment life.
