103130-03 | Lennox OEM-Upgraded Furnace Control Board Replacement

Honeywell · HVAC & Building Controls

Description  The 103130-03 is an OEM-upgraded furnace control board that replaces the original factory part in many Lennox and affiliated heating systems. It functions as the primary logic and monitoring module for ignition sequence, blower control, safety interlocks and status diagnostics.     Technical Specifications  Condition New/Never Used Surplus Brand Lennox (OEM-upgraded listing) Category HVAC Controls Part Number 103130-03 Subcategory Furnace Control Board Model Reference S9232F2002 (Lennox SureLight series) Function Ignition and blower control board for gas-fired furnace Supply Voltage 24 V control circuit (main board powered via furnace internal transformer) Supported System Types Single-stage, two-stage, communicating/non-communicating furnaces Diagnostics Display Seven-segment LED or status LEDs Compatible Replacements Replaces 103130-03, 103130-04, 103130-05 among others Typical Board Dimensions Approx. 10 in × 8 in × 1 in (varies by furnace panel) Weight ~1 lb (≈0.45 kg) OEM Usage Lennox SureLight/EL/SL series, Armstrong/Ducane equivalents Repair Difficulty Level Moderate – professional HVAC technician recommended Certification UL listed for furnace control use     Information About 103130-03 The 103130-03 board is a direct replacement and upgrade for Lennox SureLight control systems (for example the original part designation may appear as S9232F2002) using 24 V control circuits in forced-air furnace systems. It is commonly used in models from Lennox’s SL, EL, or other series units (such as SL280, EL296, SL297) that support communicating or non-communicating operation. The control board monitors a variety of inputs (flame sensor, pressure switches, limit switches, thermostat signals) and governs outputs to the inducer motor, gas valve, ignition transformer, and blower. Designed for straightforward field swap-out, the board also supports non-communicating and communicating configurations via dip-switch or link settings. In modern listings it is offered as an OEM-upgraded version by third-party suppliers replacing the original hardware. Key Features: Direct Replacement Compatibility: Drop-in fit for Lennox part number 103130-03 (and commonly 103130-04/05) ensuring broad model coverage. Ignition Control Integration: Manages ignition sequencing, flame detection, and safety shutdowns in gas-fired furnaces. Blower & Motor Coordination: Supervises blower relay or ECM signals, fan timing, and post-purge operations for efficient airflow control. Diagnostic LED Display: Seven-segment display or LED status codes allow technicians to interpret fault codes or system status quickly. Support for Communicating & Non-Communicating Systems: Configurable for both standard thermostat systems and Lennox iComfort® enabled units. Safety & Sensor Monitoring: Continuously checks flame sensor continuity, pressure/draft switch status, limit switch, rollout switch and other key safety interlocks. High-Quality Construction: Designed for reliable operation over many years, with robust circuitry to withstand furnace cycling and electrical stress. Broad Brand Cross-Compatibility: While Lennox-branded, the board is offered as a replacement for Armstrong, Ducane, Allied models as well when those use the 103130-03 series control board. Ease of Installation: Pre-configured mounting points and standard control harness connectors minimize installation time and error risk. The 103130-03 delivers the reliability and precision required for furnace system control board replacement in mid- to high-efficiency residential units.
