Carrier LH33WZ520 Flame Sensor The Robertshaw 1980-024 is aThe Carrier LH33WZ520 Flame Sensor is a critical OEM replacement part designed for combustion safety in gas fired furnaces. This sensor operates via flame rectification, passing a small microamp signal through the burner flame to the integrated furnace control (IFC). When the silicon carbide igniter or hot surface igniter successfully lights the burners, this flame rod detects the presence of ions within the flame. If the furnace control board fails
