Utica-Dunkirk 44819-002 Pressure Switch
The Utica-Dunkirk 44819-002 Pressure Switch is a critical safety component designed for precise differential pressure sensing in high-efficiency venting systems. Calibrated to a specific 0.35" WC set point, this Tri-D 2615 series switch ensures the inducer fan is generating sufficient draft before allowing the ignition sequence to proceed. As a veteran-grade OEM replacement part, it features a distinctive blue housing for rapid field identification and is engineered to withstand the thermal cycling common in residential boiler and furnace applications. Proper installation of this combustion air pressure switch is essential for preventing hazardous conditions like flue gas spillage. Technical specifications include a 2615-PSI range and a Tri-Dial configuration, making it a drop-in solution for contractors servicing Utica and Dunkirk heating systems. By monitoring the vacuum within the heat exchanger, this switch provides the reliable feedback loop required for stable HVAC system performance and safety compliance during the heating season.
Key Benefits- Factory-Calibrated Precision: Fixed at a .35-inch water column setting to meet strict OEM airflow requirements.
- Direct OEM Compatibility: Specifically engineered for seamless integration into Utica-Dunkirk boiler and furnace assemblies.
- Durable Construction: Built with high-grade internals to resist corrosion and diaphragm fatigue in demanding flue environments.
- Enhanced System Safety: Critical for detecting inducer motor failure or blocked vent conditions to prevent unsafe operation.
Is the blue housing indicative of a specific pressure range?
Yes, in this product line, the blue color coding typically identifies the .35" WC trip point, distinguishing it from switches used in higher-pressure or secondary-stage furnace applications.
What causes a pressure switch like the 44819-002 to fail?
Common field issues include diaphragm perforation, moisture buildup in the sensing lines, or terminal corrosion. Always check for a blocked flue or failing inducer motor before replacing the switch.
Can I use this to replace a switch with a different WC rating?
No. For heating equipment, it is mandatory to match the 0.35" WC rating exactly to ensure the unit operates within the manufacturer's specified safety parameters.
