Utica-Dunkirk 550001528 Flame Sensor

Maintaining a reliable rectification signal is critical for preventing nuisance lockouts in Utica and Dunkirk gas-fired boilers. The Utica-Dunkirk 550001528 Flame Sensor is a high-precision OEM component designed to monitor burner ignition and ensure the safe operation of your heating system. Engineered for professional-grade HVACR applications, this sensor features a high-sensitivity flame detection rod that communicates directly with the ignition control module to confirm the presence of a stable pilot or main burner flame. In high-demand gas-fired heating systems, carbon buildup on an older sensor can lead to short cycling or ignition failure codes; replacing it with this robust, corrosion-resistant sensor ensures the HVAC safety parts in your furnace or boiler are functioning within factory specifications. Designed for direct replacement compatibility, it simplifies heating system maintenance by providing a stable microamp signal to the control board, even in harsh combustion environments. Trust this genuine part for rapid response times and consistent performance in residential or commercial gas-fired units.

• Ensures accurate flame rectification to prevent unsafe gas accumulation and system lockouts.
• Constructed with high-heat-resistant materials to withstand consistent exposure to the burner flame.
• Precision-engineered for seamless integration with Utica and Dunkirk control modules.
• Facilitates a consistent microamp signal for reliable flame-sensing performance.
• Reduces diagnostic time by eliminating intermittent failures associated with worn or corroded sensors.

• What causes a flame sensor to fail? Most failures result from soot accumulation, oxidation, or ceramic cracking, which disrupts the electrical path needed to signal the control board.
• How do I know if I need a 550001528 replacement? If your boiler starts and then shuts off after a few seconds (short cycling) or displays a flame failure error code, the sensor is often the primary culprit.
• Is this compatible with all Utica boilers? This part is specifically sized for models requiring the 550001528 part number; always verify your specific model's parts list to ensure the correct rod angle and length.
