Utica-Dunkirk 550001528 Flame Sensor Overview
The Utica-Dunkirk 550001528 is an OEM replacement flame sensor designed to maintain safe and efficient burner operation in compatible Utica-Dunkirk boiler systems. Flame sensors are a critical safety component — they detect the presence of a burner flame and signal the control board to confirm ignition. If no flame is detected, the control board locks out the system to prevent unburned gas from accumulating, protecting both the equipment and the occupants.
Key Features
- OEM replacement part for compatible Utica-Dunkirk boiler models
- Detects burner flame to confirm safe ignition and continuous operation
- Triggers control board lockout if flame is not sensed, preventing unsafe conditions
- Designed for precise fit and reliable performance in original equipment applications

Application
This flame sensor is intended for use with select Utica-Dunkirk boiler models. Always verify compatibility with your specific unit’s model and serial number before installation. Consult the equipment’s service manual or a qualified HVAC technician for proper installation procedures.
Why Replace Your Flame Sensor?
Over time, flame sensors can accumulate oxidation or residue on the sensing rod, causing intermittent or failed flame detection. Symptoms of a failing flame sensor include repeated ignition lockouts, short cycling, or a boiler that lights briefly then shuts off. Replacing the flame sensor with a genuine OEM part like the Utica-Dunkirk 550001528 restores accurate flame detection and dependable system operation.
