Lennox 84W24 Replacement Kit

The Lennox 84W24 Replacement Kit is a field-critical OEM solution for restoring precise gas furnace ignition in high-efficiency systems. This comprehensive integrated control board kit is the designated replacement for the obsolete 84W2401, with current technical specifications identifying the Lennox 12X08 as the direct and improved substitute. For a veteran contractor, this kit facilitates a seamless transition for flawed Lennox SureLight systems, addressing common failure points in the furnace ignition control logic. The 12X08 ignition control kit includes a high-performance Honeywell integrated control board, a durable silicon nitride ignitor, and all necessary wiring harnesses—including 5-pin and 12-pin configurations—to ensure proper hot surface ignition timing and flame sensing. Engineered for compatibility with G60DFV, G60UHV, and G61MPV series units, this kit eliminates the complexities of piece-meal repairs by providing a factory-tested control module and igniter assembly that meet strict HVAC OEM specifications for 0.5A, 60Hz operation.

• Direct OEM Compatibility: Replaces 84W2401 and 84W23, ensuring the replacement 12X08 mounts correctly to existing chassis points.
• Enhanced Reliability: Features a 95-volt silicon nitride ignitor designed for superior thermal shock resistance compared to older carbide versions.
• Advanced Diagnostics: The included Honeywell S9230F1014 board provides clear LED error codes for rapid troubleshooting of flame failure or pressure switch issues.
• Full Installation Hardware: Comes with igniter brackets, diagnostic labels, and conversion stickers to maintain clear service records inside the burner box.

• Is the 12X08 a direct drop-in for the 84W24? Yes, the 12X08 is the official manufacturer-superseded part for both 84W24 and 84W2401, designed to handle the specific sequence of operations for Lennox furnaces.
• Why does my furnace show alternating fast-blinking LEDs? This typically signals a furnace igniter failure or incorrect voltage. Replacing the board and ignitor together with this ignition control kit usually resolves these communication and power errors.
• Can I use my old igniter bracket? While some brackets may look similar, it is highly recommended to use the new bracket included in the Lennox replacement kit to ensure proper ignitor positioning relative to the burner ports.
