Lennox 28W91 Ignition Wire
The Lennox 28W91 Ignition Wire is a critical 70-inch high-voltage lead engineered for precise spark delivery in residential and commercial HVAC ignition systems. As a veteran-grade OEM Lennox replacement part, this 70" ignition cable (model 100035-02) features heavy-duty insulation designed to withstand the high-thermal environment of a furnace combustion chamber without dielectric breakdown. The 70-inch length provides necessary slack for complex routing, ensuring a secure connection between the ignition control board and the spark electrode or spark plug. In the field, maintaining high-integrity conductivity and insulation is paramount to preventing intermittent ignition failures and ensuring consistent furnace spark ignition performance under heavy cycles.
Key Benefits- Optimized 70-Inch Reach: Extended length allows for flexible routing and precise positioning in large-scale furnace cabinets and industrial heating units.
- Durable Dielectric Insulation: Engineered to eliminate voltage leaks and electromagnetic interference, ensuring the full electrical impulse reaches the spark electrode.
- Direct OEM Compatibility: Replaces Lennox 28W91 and 100035-02, guaranteeing a perfect fit on specified Lennox furnace models.
- High-Temperature Resistance: Constructed with robust materials that maintain structural integrity during prolonged exposure to heating system exhaust and ambient heat.
Is the Lennox 28W91 compatible with all Lennox furnaces?
While this 70" ignition wire is a widely used Lennox OEM part, compatibility is model-specific. It is primarily utilized in systems requiring an extended lead to reach the ignition source.
What are the symptoms of a failing ignition wire?
The most common field indicators include visible cracking in the insulation, carbon tracking, or an audible "clicking" sound from a spark jumping to the chassis rather than the burner, often resulting in a furnace ignition failure code.
Can I trim the 28W91 wire to a shorter length?
Field modification is not recommended. This part is factory-terminated to ensure a low-resistance connection; altering the ignition cable can compromise the spark intensity and system safety.
This item is not eligible for free shipping.
