Replacement Ignitor

This replacement control board is a 2-stage variable speed ignition control board engineered for gas furnace systems operating on 18-30 VAC 60 Hz input. Measuring 1.85in x 8.125in x 4.15in, this compact unit is designed as a direct replacement for Lennox HVAC systems and serves as the equivalent to Honeywell S9230F1014 boards. The board features 2-stage operation capability and requires a 95V igniter (part 100536-01) for proper functionality. It is not compatible with 80V SureLight igniter systems, so compatibility verification is essential before installation. The unit includes built-in heating isolation relay technology and offers multiple accessory terminals for expanded system control. The EAC terminal energizes electronic air cleaners with indoor blower operation at 1 amp capacity, while the HUM terminal energizes humidifiers when CAI is active on heat calls, also at 1 amp. Diagnostic troubleshooting is simplified through an integrated red LED that flashes in programmable X and Y code patterns, allowing technicians to quickly identify furnace status and system faults without requiring external diagnostic equipment. This intelligent diagnostics feature significantly reduces service time and minimizes guesswork during installation and maintenance. Ideal for HVAC contractors, maintenance professionals, and facility managers responsible for commercial and residential heating system repairs and upgrades, this control board provides reliable performance and straightforward diagnostics to minimize downtime and ensure optimal furnace operation.
