Utica-Dunkirk 240008781 Control

The Utica-Dunkirk 240008781 Electronic Ignition Control is a critical OEM component engineered for high-performance gas-fired boilers, specifically designed as a direct replacement for MGB and MGC series boiler models. This Honeywell S9361A2060 integrated high limit control provides precise management of ignition timing and flame sensing, ensuring optimal combustion efficiency and reducing potential downtime caused by intermittent signal failure. For technicians servicing ECR International family brands including Dunkirk, Pennco, and Utica Heating, this control module serves as an exact drop-in replacement to restore factory-specified performance and safety parameters.

Operating on a 120V / 60Hz secondary electrical service, the Utica-Dunkirk 240008781 ignition module utilizes advanced microprocessing to monitor the ignition sequence and high-limit safety thresholds. It is essential to verify that your specific unit utilizes the two-wire pilot design, as this module is the designated service part for older pilot configurations and is not interchangeable with newer single-wire systems (240011101). Utilizing this gas boiler control board ensures the system retains its original AHRI ratings and operational certifications, maintaining the precise 4.5-second flame proving window required for safe burner stabilization and consistent heat exchange.

• Direct OEM Compatibility: Engineered specifically for Utica MGB and Dunkirk MGC series boilers to ensure seamless integration.
• Enhanced Ignition Reliability: Provides stable burner operation and precise electronic ignition control to prevent nuisance lockout errors.
• System Safety Integration: Incorporates an integrated high limit control to monitor water temperature and prevent overheating conditions.
• Technical Accuracy: Restores original manufacturer specifications for ignition timing and sound quality requirements.

Is the 240008781 interchangeable with newer Utica pilot assemblies?
No. This control is designed for the older two-wire pilot system. If your boiler has been upgraded to the newer single-wire pilot assembly, you must use the 240011101 control instead.

What does it mean when the control displays Error 62 (ERR62)?
Error 62 typically indicates a flame signal recognition issue or ignition failure. If troubleshooting confirms the control is not sensing the pilot, this module is the designated replacement to resolve the lockout.

Can this control be used on both natural gas and LP configurations?
Yes, the Utica-Dunkirk 240008781 is compatible with both fuel types, provided it is installed within the matching boiler series and pilot configuration.
