Utica-Dunkirk 127000014 Pressure Switch

Ensure system safety and operational integrity with the Utica-Dunkirk 127000014 High Pressure Switch. This critical safety component is engineered as a manual reset pressure switch, designed to trip and interrupt the heating circuit if internal boiler pressures exceed safe thresholds. Specifically calibrated to opens at 415 PSI, this limit control acts as a terminal failsafe, protecting the heat exchanger and hydronic piping from over-pressurization during abnormal operating conditions.

For veteran technicians, the 127000014 pressure switch provides the reliable mechanical sensing required in high-demand industrial and commercial boiler applications. As a genuine Utica Dunkirk boiler part, it offers exact physical and electrical compatibility, eliminating the HVAC pressure switch troubleshooting issues often associated with generic alternatives. The M/R high pressure switch configuration ensures that once a high-limit event is detected, a manual inspection is required before the system can be brought back online, prioritizing equipment longevity and site safety.

• Precise Safety Calibration: Factory-set to trigger at 415 PSI to prevent catastrophic system failure.
• Manual Reset Functionality: Requires a physical reset, forcing a technician to verify the cause of the high-pressure spike.
• Robust Build Quality: Constructed to withstand the high-temperature environments of commercial boiler rooms.
• Direct OEM Replacement: Ensures seamless integration with existing Utica Dunkirk HVAC parts and control boards.

What causes this switch to trip? Typically, a pressure spike above 415 PSI is caused by an expansion tank failure, a faulty high-limit aquastat, or air trapped within the hydronic loop. Always verify system gauge accuracy before replacing the switch.

Can I bypass the manual reset for testing? Bypassing safety controls is never recommended. If the 127000014 opens at 415 PSI, use a calibrated manometer to verify if the boiler is truly over-pressurizing or if the switch diaphragm has fatigued.

Is this switch compatible with residential boilers? Consult your specific model's parts list; while common in larger Utica and Dunkirk units, ensure the 415 PSI setpoint matches your system's design specifications.
