Compatible with Honeywell S8610U Intermittent Pilot Control Module
This ignition module supports Honeywell S8610U, S8610U1003, and S8610U3009 controllers with intermittent pilot ignition. It’s designed with a flame monitoring function that automatically cuts off fuel if ignition fails within about six minutes, enhancing safety and minimizing gas leaks. The unit supports single, double, and remote sensing configurations, offering flexibility for different furnace setups. The design emphasizes plug-and-play compatibility with original interfaces, cutting installation time, though professional installation is advised for safety and proper matching.
50A55-843 Integrated Furnace Control Board
This integrated control board is designed to manage ignition sequences and safety shutoffs with a built-in microprocessor. It supports multiple part numbers in the 50A55-843 family, indicating broad compatibility with White Rodgers and other system configurations. Key features include automatic gas interruption ignition control, flame sensing, and thermostat interaction to ensure safe operation. The board’s robust construction aims to withstand heat and vibration, extending furnace service life. Installation typically benefits from professional handling due to wiring and port compatibility requirements.
50A55-843 Ignition Control Module — NEALMART
The NEALMART 50A55-843 ignition module uses microprocessor-based automatic control to monitor the gas burner, inducer, and fan. It interprets signals from the thermostat and flame sensor to ignite the burner and monitor flame status, then shuts off when appropriate. Electrical specs include a 25 VAC input with various relay outputs for valves, ignitors, and circulators. The unit emphasizes safety and reliability, with a fuse-protected low-voltage circuit. Installation should consider compatibility with existing wiring and the furnace’s control strategy.
The ROP Shop Universal TransistORIZED Ignition Module
The ROP Shop offers a replacement ignition module kit designed as a transistorized ignition module replacement. Included are the ignition module, a wire connector, a wire nut, screws, and instructions. This kit provides a practical, affordable option for homeowners or technicians seeking a straightforward replacement that aligns with similar electronic ignition architectures. Compatibility with a broad range of ignition systems makes it suitable for various furnace models, though exact fit should be verified by comparing connector types and wiring diagrams.
S8610U Furnace Control Board Module (2 Pack) — Apzte
This is a second listing of the Apzte brand two-pack universal ignition module tailored for Honeywell S8610U3009 and S8610U1003 controllers. It emphasizes compatibility with natural or LP gas systems and notes a part number focus on S8610U controllers. The two-pack option supports maintenance planning and parts replacement strategies, allowing for quick swaps if ignition issues arise. As with other modules, verify wiring compatibility and ensure the unit matches the specific furnace model and control board version before installation.
S8610M3009 S8610U Furnace Control Board Module Replacement
This Apzte module targets Honeywell S8610U3009 and S8610U1003 configurations for intermittent pilot furnaces and residential boilers.

Prospective buyers should confirm that the model is intended for intermittent pilot setups rather than standing pilot systems and ensure correct wiring harness compatibility with their furnace control panel. The module aims to provide reliable ignition sequence control with safe flame monitoring.
Buying Guide: Key Purchase Considerations
When selecting a universal ignition control module, consider the following factors to ensure proper fit and safe operation:
- Compatibility: Verify the exact model numbers of your furnace’s ignition controller (for example, S8610U3009 or S8610U1003) and confirm the new module supports intermittent pilot systems if that is your furnace type.
- Gas Type and Configuration: Ensure the module supports natural gas or LP gas as needed, and confirm whether your system uses single-barrel, double-barrel, or remote sensing configurations.
- Safety Features: Look for flame monitoring, automatic shutoff on failed ignition, and proper isolation of gas supply when faults are detected. These features reduce the risk of gas leaks and improve safety.
- Electrical Requirements: Check input voltage (commonly 24–25 VAC) and relay ratings for valves, ignitors, and circulators to prevent overloading circuits.
- Installation Type: Some modules are plug-and-play with existing harnesses, while others require wiring adaptation. Professional installation is recommended when in doubt to ensure proper matching and safety.
- Durability and Build Quality: Consider manufacturing quality, PCB design, and resistance to heat and vibration, which affect long-term reliability in furnace environments.
- Warranty and Support: A product with a clear warranty and accessible customer support can help address compatibility questions post-installation.
