Fenwal 35-703917-007 Control
The Fenwal 35-703917-007 is a high-performance 120V Direct Spark Ignition (DSI) control designed for precise microprocessor-based burner management. Engineered for natural, LP, and manufactured gas applications, this Fenwal ignition module features a 0-second pre-purge and a 15-second trial for ignition (TFI) window. As a veteran-grade HVACR replacement part, it incorporates a diagnostic LED that provides immediate feedback via three distinct error codes, significantly reducing troubleshooting time on-site. The 35-703917-007 ignition control is polarity insensitive, which mitigates the risk of miswiring during field installation. With a rugged operating temperature range of -40°F to 175°F, it ensures reliable gas burner flame sensing through flame rectification. This unit includes built-in flame current test pins for instant signal verification and is designed to manage a single gas valve and high-voltage spark electrode efficiently.
Key Benefits- Precise Microprocessor Timing: Delivers 100% repeatable 15-second TFI cycles for consistent burner starts.
- On-Board Diagnostics: Rapidly identify system faults using the multi-code LED indicator.
- Safety-First Logic: Automatic 1-hour reset and immediate 0.8-second flame failure response time.
- Simplified Installation: Polarity insensitive 120 VAC input and 1/4" quick-connect terminals for fast retrofitting.
- Advanced Flame Sensing: Minimum 1.0 μA flame current requirement ensures stable operation in demanding environments.
How do I check the flame signal on this Fenwal module?
Use a DC micro-ammeter connected to the FC+ and FC- test pins. A stable reading of 1.0 μA or higher is required to maintain the flame circuit.
What does a steady LED light indicate during operation?
A steady-on LED typically signals an internal hardware or software fault, requiring a power reset or control replacement if the condition persists.
Can this control replace older analog Fenwal models?
Yes, the 35-70 series is the designated microprocessor upgrade for legacy 05-13, 05-14, and 05-38 analog controls, offering superior timing accuracy.
