Application

Always verify compatibility with your specific model and serial number 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 buildup on the sensing rod, reducing their ability to detect a flame accurately. This often results in the appliance locking out on a “no flame” fault even when the burner is functioning correctly. Replacing the sensor with a genuine OEM part restores proper flame signal strength and eliminates unnecessary service calls.
