Carrier LH33WZ520 Flame Sensor and aluminum tubing across allThe 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
