Lennox 68M28 Ignition Control Kit

The Lennox 68M28 Ignition Control Kit is the specified OEM replacement for restoring sequence logic and burner ignition in Lennox PGE10, PGE12, GCS26, and GCS29 packaged units. This comprehensive retro-fit kit centers around the 60M32 integrated blower control and is engineered to supersede legacy GCI-1 and GCI-2 boards. When upgrading from a GCI-1, this kit provides a necessary transition from the older two-rod sensing system to a dedicated three-rod electrode setup, ensuring a more stable flame rectification signal. The included high-voltage ignition cable and 42-inch flame sensor wire address common system lockout issues caused by carbon fouling or insulation breakdown in older harnesses.

As a veteran tech, you know that timing is everything. This furnace control board kit manages the 30-second pre-purge, the 10-second trial for ignition, and the 30-second blower-on delay with industrial precision. By utilizing the LB-107357 ignition module, you maintain direct spark ignition (DSI) reliability while benefiting from clear LED diagnostic codes for faster troubleshooting on the roof. The kit simplifies the conversion process with dedicated adapter harnesses, preventing the need for field-splicing original thermostat wiring or gas valve leads.

• OEM Compatibility: Exact replacement for Lennox part numbers 46K68, 81K76, and 97L20, ensuring zero-footprint mounting with the included adapter plate.
• Enhanced Flame Sensing: Upgrades GCI-1 systems to a modern 42-inch white flame sensor wire and 3-rod electrode for superior current detection.
• Advanced Diagnostics: On-board LEDs provide instant feedback for pressure switch failures, auxiliary limit trips, and flame failure lockouts.
• Complete Installation Kit: Includes the 60M32 board, adapter harnesses, high-voltage ignition cable, and mounting hardware to minimize downtime.

• Can I use this to replace a 60M32 board that is already installed? Yes, if the unit already has a 60M32, this is the direct replacement; however, the harnesses may not be required if the existing wiring matches the 6-pin and 5-pin plugs.
• What do the LED flash codes mean? A slow flash indicates normal standby, a fast flash signifies a call for heat, and 2 or 3 flashes point to ignition failure or pressure switch issues, respectively.
• Is a separate flame sensor required? Yes, this kit moves the sensing logic away from the ignition cable to a dedicated sensor, which is included in the box.
