Lennox 19J95 Control Kit

The Lennox 19J95 Control Kit is an OEM-specified integrated ignition control replacement engineered specifically for SLP98 and SLP99 gas furnace series. As a veteran-grade furnace circuit board replacement, this kit is the direct operational successor to legacy part numbers 15M50 and 102813-02. It serves as the primary furnace ignition control logic, managing the 120V ignitor firing sequence, flame rectification, and synchronous gas valve operation to ensure precise combustion cycles. This board is fully compatible with both communicating (iComfort) and non-communicating thermostat systems, providing HVAC contractors with flexible installation parameters for high-efficiency Lennox residential units.

For technicians in the field, the Lennox replacement control kit 19J95 includes a 7-segment LED diagnostic display, facilitating rapid troubleshooting of system lockouts and component failures. It is designed to interface exclusively with 120V ignitors (part number 100536-02) and should not be deployed in units using 95V ignition hardware. By integrating the latest furnace control board firmware, this kit optimizes blower motor ramps and ignition timing, critical for maintaining the high AFUE ratings of the Lennox Dave Lennox Signature Collection furnaces. This 24V integrated control ensures robust flame sensing and safety monitoring, effectively preventing gas accumulation during failed ignition attempts.

• Direct OEM Compatibility: Engineered as a drop-in replacement for obsolete 15M50 and 102813-02 Lennox furnace parts, ensuring exact physical fit and wiring alignment.
• Integrated Diagnostics: Features an on-board 7-segment display that provides real-time error codes, reducing time spent on system diagnostics.
• Dual-Mode Communication: Supports advanced communicating iComfort protocols while remaining backward-compatible with standard 24V HVAC controls.
• Precision Safety Logic: Actively monitors flame rollout, pressure switches, and limit circuits to maintain safe furnace operation.

• Can I use the 19J95 with a 95V ignitor? No. This control is designed strictly for 120V ignition systems. Installing it with a 95V ignitor will result in immediate component failure.
• Is manual configuration required for the unit size code? Yes. Technicians must set the DIP switches and configure the unit size code on the LED display to match the furnace's original specifications during installation.
• Does this board replace the 102813-05 model? Yes, the 19J95 kit utilizes the latest 102813-05 integrated control as its core component for the SLP98V and SLP99V series.
