This premium replacement flame sensor with a 64 1/2-inch lead wire is a vital safety component for modern heating systems and commercial HVAC units. Designed to detect the presence of a flame during the ignition process, this sensor uses flame rectification to signal the control board that it is safe to keep the gas valve open. If your furnace or rooftop unit experiences frequent short-cycling or shuts down immediately after ignition, a corroded or failing flame sensor rod is often the cause. This high-quality sensor features a durable metal rod and a heat-resistant ceramic insulator, ensuring long-lasting performance in high-temperature environments. The extra-long 64.5-inch wire provides versatile routing options for larger appliance cabinets, making it an essential part for maintaining reliable and safe heating operation.
