Fenwal 35-615922-125 Module
The Fenwal 35-615922-125 is a professional-grade 24VAC DSI module specifically engineered for Greenheck make-up air units and high-demand gas-fired appliances. This microprocessor-based direct spark ignition control provides precise sequence management, integrating an inducer blower relay to coordinate combustion airflow with the ignition cycle. As a veteran-preferred HVAC ignition control board, it features DETECT-A-FLAME technology for robust flame supervision, ensuring the gas valve only remains energized when a stable flame is verified. Designed for harsh mechanical environments, the Fenwal 35-61 platform operates reliably between -40°F and 176°F. The onboard system diagnostic LED streamlines troubleshooting by providing immediate flash codes for airflow faults or flame failures, minimizing downtime for field technicians. With a 15-second pre-purge and a 10-second trial for ignition, this module ensures safe, repeatable start-ups across natural gas and LP applications, making it the standard replacement ignition module for maintaining specialized Greenheck equipment.
Key Benefits- Advanced Diagnostics: Built-in diagnostic LED provides rapid flash-code feedback for pressure switch faults and ignition lockouts.
- Integrated Blower Control: Features a dedicated inducer blower relay to manage the full combustion cycle from a single point.
- Enhanced Safety: High-speed microprocessor control continuously monitors flame current and airflow integrity during operation.
- OEM Compatibility: Specifically programmed for Greenheck HVAC systems, ensuring correct timing and safety logic over universal alternatives.
- Flexible Sensing: Supports both local and remote flame sensing configurations to match specific burner geometries.
What does a steady LED light or specific flash code mean on this Fenwal module?
The diagnostic LED indicates system status; a steady light usually signifies normal operation, while specific patterns point to airflow restrictions, flame signal loss, or internal hardware faults. Always reference the Fenwal 35-61 series manual for the exact code definitions.
Can the 35-615922-125 replace other 35-61 series ignition boards?
While the base platform is similar, the 35-615922-125 features a specific Greenheck configuration. You must verify that the pre-purge, inter-purge, and trial-for-ignition timings match your original equipment to maintain safety certifications.
How do I measure the flame signal on this control board?
Technicians can measure the flame current by connecting a DC micro-ammeter to the FC+ and FC- terminals. A healthy signal typically reads 1.0 μA DC or higher during the burner cycle.
