Lennox 84K65 Ignitor/Sensor
The Lennox 84K65 Ignitor/Sensor is a critical OEM replacement component designed for precise ignition and flame rectification in high-efficiency furnace systems. This dual-purpose spark ignitor and flame sensor is engineered to withstand the rigorous thermal cycling of commercial and residential HVAC units. The 84K65 is identical to R42446-001, ensuring a direct-fit solution for technicians servicing legacy and current Lennox-platform equipment. When troubleshooting furnace ignition failure, this component provides the high-voltage spark required to initiate combustion while simultaneously monitoring the flame signal to prevent hazardous gas buildup. Its robust ceramic insulation and high-grade electrode material minimize oxidative degradation, ensuring reliable furnace start-up and consistent performance. This Lennox replacement part is essential for restoring the safety sequence of the integrated furnace control board, making it a standard inventory item for contractors prioritizing OEM furnace repair parts and system longevity.
Key Benefits
- Direct OEM Compatibility: Ensures seamless integration with Lennox control boards requiring a secondary flame rectification signal.
- Dual-Function Design: Combines spark ignition and flame sensing into a single footprint to simplify HVAC troubleshooting and installation.
- High-Temperature Durability: Engineered with premium materials to resist carbon fouling and thermal shock during heavy heating cycles.
- Verified Cross-Reference: Confirmed match for 84K65 and R42446-001, eliminating guesswork during emergency service calls.
Common Questions
Will this ignitor fix a 'no flame' lockout code?
If your control board indicates a flame sense failure or ignition lockout, replacing the Lennox 84K65 often resolves the issue, provided the burner ground is clean and the gas valve is functional.
Can I use this to replace a hot surface ignitor (HSI)?
No, this is a spark-to-light ignitor and sensor. It is specifically designed for systems utilizing a spark ignition sequence and is not interchangeable with silicon carbide or nitride HSIs.
How do I ensure a proper flame signal after installation?
Verify that the electrode is positioned directly in the burner path and ensure the 84K65 sensor wire is securely connected to the "SENSE" or "IGN" terminal on the ignition module.
