Lennox 98M85 Ignitor
The Lennox 98M85 Ignitor (also identified by part number 100220-01) is an OEM silicon nitride hot surface ignitor designed for high-performance gas furnace applications. Engineered specifically for Lennox, Armstrong, and Ducane heating systems, this replacement furnace ignitor produces a precise, high-temperature spark to ensure consistent fuel ignition and reliable startup cycles. Unlike standard glass or silicon carbide alternatives, the 98M85 features a durable electrode assembly construction capable of withstanding the rapid thermal expansion and harsh oxidation environments found in modern high-efficiency HVAC units.
Field technicians prefer this genuine OEM Lennox part because it maintains exact ignitor compatibility with existing control board timing sequences, preventing "no-light" codes and nuisance flame-sensing lockouts. For contractors performing furnace repair, the Lennox 98M85 provides a seamless drop-in fit, restoring the furnace to its original factory specifications for combustion efficiency and operational safety.
Key Benefits- OEM Compatibility: Exact replacement for 98M8501 and R100220-01, ensuring a perfect fit in Lennox and Armstrong-Air units.
- Silicon Nitride Durability: Advanced ceramic material offers superior resistance to physical vibration and high-temperature cycling.
- Reliable Ignition: Designed to provide rapid heat-up and a concentrated spark for immediate gas ignition.
- Universal Replacement: Successfully replaces older, less efficient hot surface ignitor models in compatible equipment.
What are the symptoms of a failing Lennox 98M85 ignitor?
Common signs include the furnace blower running without heat, visible cracks on the ignitor element, or the control board flashing a "low flame signal" or "ignition failure" code. A technician can verify failure using a multimeter to check for an open circuit or high resistance.
Can I use a universal ignitor instead of the 98M85?
While universal kits exist, using the Lennox 98M85 ensures the mounting bracket and electrical connector match the furnace's original design, maintaining the safety integrity and ignition timing of the system.
How do I handle a silicon nitride ignitor during installation?
Avoid touching the element with bare hands. Skin oils can create "hot spots" that accelerate degradation. Always handle the part by the ceramic base or the provided mounting bracket.
