Lennox 10W56 Ignition Control
Install the Lennox 10W56 Ignition Control Module to restore precise timing and safety monitoring to your residential gas heating system. As a direct OEM replacement part, this integrated solid-state control manages the 24VAC ignition sequence, ensuring consistent burner light-off and flame supervision. Known technically as part number 100253-01, this unit replaces legacy modules found in various Lennox and Allied Air configurations, including the 15GCSX series. It features a high-impact, durable construction designed to withstand the thermal stress of a furnace vestibule while providing critical flame sensing and lockout protection.
For field technicians, the 10W56 provides a streamlined installation with standard 1/4 inch spade terminals for simplified wiring. This furnace ignition board operates on a 50/60Hz frequency and is rated for a maximum of 0.5 Amps, making it compatible with both natural gas and propane (LP) applications. By maintaining the strictly defined ignition trial periods and pre-purge cycles, it prevents gas accumulation and short-cycling, ensuring the unit meets factory performance standards for residential gas furnaces.
Key Benefits- Broad Compatibility: Direct substitute for Lennox 100253-01 and cross-referenced with multiple HVAC ignition modules in the 15GCSXAV and BV series.
- Safety Logic: Features integrated flame sensing and automatic lockout functionality to prevent hazardous gas buildup during ignition failure.
- Technical Reliability: Engineered as a solid-state ignition control to provide more stable voltage output and timing than mechanical equivalents.
- Universal Fuel Support: Optimized for use in systems configured for either natural gas or liquid propane.
Is the 10W56 compatible with my specific Lennox model?
This part is a standard replacement for the 100253-01 series. To confirm fitment, verify the part number on your existing board or check the wiring diagram for compatibility with 24VAC Hot Surface Ignition (HSI) or Intermittent Pilot setups.
What does a flashing LED on this control board indicate?
Diagnostic codes vary by specific board revision, but typically, a slow flash indicates a call for heat without flame sense, while a fast flash or steady light can indicate an internal failure or lockout due to failed ignition attempts.
Can I use this for both 50Hz and 60Hz power supplies?
Yes, the Lennox 10W56 is rated for 50/60Hz, making it suitable for standard North American grid specifications and specific international applications.
