Utica-Dunkirk 14662803 Ignition Module

The Utica-Dunkirk 14662803 Ignition Module is a critical OEM replacement control board designed for high-efficiency residential and commercial boilers. Specifically engineered for the Utica UB90 Series II and Dunkirk Q90 series, this module manages the entire firing sequence, including the draft inducer purge cycle, spark-to-pilot ignition, and constant flame rectification sensing. As a direct replacement for the United Technologies 1013-15 (and legacy 1013-10 models), it provides precise 120V AC timing control and a 24V AC interface to the gas valve, ensuring reliable burner operation in high-temperature environments.

For technicians troubleshooting no-heat calls, the 14662803 ignition control features onboard diagnostic LED indicators that assist in identifying lockout conditions or voltage drops across the safety circuit. This microprocessor-based board is essential for maintaining the AFUE rating of gas-fired systems by optimizing ignition trial times and monitoring for nuisance shutdowns caused by improper grounding. When replacing a failed UT 1013-15 control, this genuine Utica/Dunkirk part ensures seamless integration with existing wire harnesses and aquastat connections for immediate restoration of boiler functionality.

• OEM Compatibility: Exact replacement for Utica 146-62-803 and United Technologies UT 1013-15.
• System Safety: Monitors flame presence and manages safety shutdowns to prevent hazardous gas accumulation.
• Diagnostic Intelligence: Integrated LEDs provide real-time feedback on system status and fault codes.
• Industrial Build: Rugged construction designed to withstand the ambient heat of boiler vestibules.
• Plug-and-Play: Pre-programmed for specific Utica and Dunkirk boiler ignition sequences.

What are the signs of a failing 14662803 module?
Common indicators include intermittent ignition failure, the spark failing to stop once the pilot is lit, or a diagnostic LED flashing a specific code. If the boiler experiences a "no-click" event during a call for heat despite 24V delivery from the thermostat, the control board may be grounded out or defective.

Can this board replace other United Technologies modules?
The 14662803 is specifically cross-referenced to Replace UT 1013-15 and 1013-10. Always verify the part number on your existing board before installation as these modules are programmed with specific trial-for-ignition timings critical to equipment safety.

Why is my new module going into lockout?
Lockouts are often caused by poor grounding or a dirty flame sensor. Ensure the ground wire is secured to the burner chassis and that the flame rectification signal meets the minimum microamp requirement specified by Utica-Dunkirk.
