Replacement Ignitor

This hot surface ignitor is a direct replacement component for Lennox LEN41K56 gas furnace heating systems. Featuring a durable silicon nitride element, this ignitor delivers reliable, fast ignition by rapidly heating incoming gas to combustion temperature, ensuring consistent system performance and startup reliability. The unit operates at 80V (50/60 Hz) with 92 watts of power output and measures 54mm in element length, making it ideal for retrofit and maintenance applications in commercial and residential HVAC installations. The ignitor utilizes proven SureLight hot surface ignition technology and incorporates a White Rodgers 768A-4 ignitor assembly, designed specifically for compatibility with White Rodgers control systems. Construction includes a steatite ceramic insulator body with white Teflon-coated lead wires and a 2-terminal AMP receptacle connector featuring 0.084-inch female sockets for secure, foolproof connections. Optional zinc-plated steel mounting tabs accommodate various installation configurations. With a resistance range of 10.9 to 19.7 ohms at 25 Degrees C, this component meets original equipment specifications for Lennox furnace systems. The silicon nitride heating element provides extended service life and superior thermal performance compared to conventional ignitors. This replacement part is essential for HVAC technicians and facility managers performing routine maintenance, repairs, or system upgrades on compatible Lennox heating equipment. Proper installation with compatible control systems ensures optimal ignition timing and furnace efficiency.
