Fenwal 35-605924-113 Ignition Module

The Fenwal 35-605924-113 is a 24VAC microprocessor-based direct spark ignition module engineered for precise control of gas valves and igniters in commercial and residential heating systems. Often found in Coleman HVAC units, this DSI control board features a non-volatile lockout and provides high-voltage energy to the electrodes via a dedicated S8610U replacement alternative configuration. It serves as the 05-279000-023 direct replacement, ensuring backward compatibility with older Fenwal footprints while maintaining system safety through continuous flame monitoring. The 35-605924-113 ignition control utilizes a 15-second trial for ignition and a 30-second prepurge period to stabilize atmospheric conditions within the burner assembly. Its multi-pin connector design facilitates rapid HVAC furnace board troubleshooting by isolating wiring faults from module failures. For contractors performing a Fenwal ignition module replacement, this unit integrates seamlessly with existing manifold gas valves and sense electrodes to restore reliable heating cycles.

• Direct OEM Compatibility: Specifically engineered to replace legacy 05-279000-023 modules without manifold modification.
• Microprocessor Reliability: Enhanced logic for flame sensing and trial-for-ignition sequences prevents nuisance lockouts.
• Robust Construction: Designed to withstand the high-temperature environments of Coleman heating cabinets.
• Safety Monitoring: Automatic 100% shut-off upon flame failure protects the heat exchanger and surrounding components.

How do I resolve a lockout on the Fenwal 35-605924-113?
Perform a hard reset by cycling the 24VAC power; if the unit fails to sense flame after the trial period, inspect the electrode gap and ensure the ground wire is properly bonded to the burner chassis.

Is this module compatible with intermittent pilot systems?
No, this is a direct spark ignition module. It is designed to spark directly at the main burner and does not utilize a pilot assembly.

What is the standard prepurge timing?
This specific model features a 30-second prepurge to clear the combustion chamber before the 15-second ignition trial begins.
