The Utica-Dunkirk 1401003 is a critical safety component designed for high-efficiency gas furnaces and boilers. This SPDT pressure switch is factory-calibrated to a 0.50" WC setpoint, ensuring precise monitoring of the inducer motor's draft pressure. Built for reliability in demanding HVACR environments, it features a 1/4" barbed connection for secure pneumatic tubing attachment. As a genuine OEM replacement part, it maintains the integrity of the unit’s combustion sequence by verifying proper venting before ignition. Contractors often specify this differential air pressure switch for its consistent performance and electrical compatibility with Utica and Dunkirk hydronic systems. Utilizing a single-pole double-throw (SPDT) configuration, it provides versatile wiring options for various control board lockout circuits. Rely on this HVAC inducer limit switch to prevent unsafe operation during venting failures or blocked flue conditions, ensuring the system operates within manufacturer-specified tolerances. Key Benefits for Technicians: Precise Calibration: Factory-set at 0.50" WC to ensure accurate pressure sensing and system safety. Standardized Connections: Features a 1/4" barbed vacuum port for quick integration with existing sensing lines. OEM Compatibility: Designed specifically as a direct-fit replacement pressure switch for ECR International brands. Durable Construction: Engineered to withstand the thermal cycling and vibration typical of inducer fan assemblies. Common Questions: Can I use this switch if my current unit is set to a different WC? No, pressure switches must match the exact water column (WC) rating specified by the manufacturer to prevent delayed ignition or nuisance tripping. What does the SPDT circuit allow for? The SPDT configuration allows for both normally open and normally closed connections, making it adaptable to various boiler control modules. Is the mounting bracket included? Mounting configurations can vary; verify if the existing bracket from the Utica-Dunkirk 1401003 can be reused or if a universal bracket is required.
