Utica-Dunkirk 550001624 Control Board Kit

The Utica-Dunkirk 550001624 Control Board Kit is a critical 120 VAC multi-element management component designed for precise sequencing and safety in hydronic heating systems. This kit is a direct replacement for Argo AT0623 electric hot water boilers and is essential for managing the primary nervous system of the unit. The board regulates high-voltage switching, integrated circuit protection, and real-time system diagnostics through an array of four green element energized LED indicators and a dedicated red fault indicator for rapid troubleshooting. By integrating high-quality resistors, capacitors, and transistors into a single UL-recognized and CSA-certified module, this kit ensures stable communication between the thermostat and the boiler’s heating elements, optimizing HVAC energy efficiency while maintaining precise temperature control profiles across residential and light commercial applications.

• Enhanced Diagnostic Monitoring: Features a 5-LED diagnostic array to distinguish between normal operation and system faults, reducing diagnostic time for field technicians.
• OEM Compatibility: Specifically engineered for Argo AT Series boilers, ensuring accurate terminal alignment and fitment without modification.
• Comprehensive Kit Components: Includes the 2-element control board, circuit breaker, 5 terminal wires, and 9 high-temp cable ties for a complete field installation.
• System Safety Standards: Verified UL and CSA certification ensures the module meets strict electrical load and safety parameters for high-voltage heating equipment.

How do I identify a fault using the Utica-Dunkirk 550001624?

The integrated red LED light indicates a boiler fault. If this illuminates while the green LEDs are inactive, check the high-limit switch and flow rates. If the red light persists despite adequate water flow, the control module may require testing for relay failure or voltage drops.

Can this board be used on other electric boilers?

This kit is specifically calibrated for the electrical characteristics of the Argo AT0623 model. Using it on non-specified models may lead to improper element sequencing or short-cycling, which can damage the boiler's heat exchanger.

Does this kit include a replacement circuit breaker?

Yes, the 550001624 is a complete control board kit that includes the main circuit breaker and necessary wiring harnesses to ensure the entire control circuit is refreshed during the repair.
