This premium left-hand flame sensor rod is an essential safety component for gas-fired heating systems and commercial HVAC units. Designed to ensure reliable ignition and operation, the sensor works by detecting the presence of a flame through flame rectification. If the burner fails to ignite or the flame is lost, this sensor signals the control board to immediately shut off the gas supply, preventing dangerous gas accumulation. This L/H flame sensor is a common replacement part for furnaces and heating units that experience short-cycling or ignition failure. Constructed with high-temperature resistant materials, it provides long-lasting durability in demanding heating environments.
