White Rodgers 50A56-956 Ignition Control
The White Rodgers 50A56-956 is a professional-grade integrated furnace control designed for 24V single-stage heating systems. This hot surface ignition (HSI) module serves as a high-reliability field replacement, specifically engineered to provide a direct replacement for 539617. Operating on a 7-second trial for ignition (TFI) sequence with 0 pre-purge time, this board manages the inducer motor, igniter, and gas valve timing with precision. For technicians troubleshooting intermittent lockout issues or board failure, this unit offers a drop-in solution that restores HVAC flame rectification and safety circuit monitoring. The 50A56-956 ignition board is built to withstand the thermal cycling typical of modern residential furnaces, ensuring consistent voltage delivery to the 120V silicon carbide igniters while maintaining strict diagnostic oversight through its onboard LED indicators.
Key Benefits for Technicians- OEM Compatibility: Seamlessly replaces the 539617 ignition control without the need for complex rewiring or harness adapters.
- Precise Ignition Timing: Features a fixed 7-second TFI and zero pre-purge for rapid heat delivery in compatible air handlers.
- Integrated Diagnostics: Internal logic monitors system faults, simplifying service calls by identifying flame signal or limit switch issues.
- Robust Field Performance: Designed for high-demand environments, managing the sequential operation of the blower motor and draft inducer.
Does this board support two-stage heating cycles?
No, the White Rodgers 50A56-956 is strictly designed for single-stage furnace applications utilizing a 24V control circuit.
Will this resolve a "no flame sense" error?
Yes, provided the flame sensor is clean and the grounding is secure; this module handles the flame rectification signal necessary to keep the gas valve energized.
Is the 50A56-956 compatible with 80V or 120V igniters?
This control is engineered to manage standard 120V hot surface igniters commonly found in legacy furnace platforms.
