Utica Boilers 1401004 Air Pressure Switch Spdt 3.5 Inches Wc 0.44 Inches Wc

Product Description

The Utica Boilers 1401004 is an air pressure switch designed for use in residential and light commercial heating systems. This switch carries a single-pole double-throw (SPDT) configuration and is rated at 3.5 inches water column (WC) with a reset point of 0.44 inches WC. HVAC technicians and boiler service professionals rely on pressure switches like this one to monitor the operation of the inducer or draft blower motor. When the inducer motor runs correctly, it creates a negative pressure that closes the switch and signals the control board to move forward in the ignition sequence. If that pressure is not achieved, the switch stays open and locks out the burner, protecting the heat exchanger and flue system from unsafe conditions.

The SPDT design gives this switch two circuit paths: one that is normally closed and one that is normally open. This allows the boiler control board to monitor both the presence and the absence of adequate combustion air pressure. A faulty or stuck pressure switch is one of the most common causes of a no-heat call in gas-fired boilers, making a reliable replacement part critical for fast, accurate diagnostics and repair. The 1401004 is a direct replacement part sourced from Utica Boilers, ensuring compatibility with the systems it was engineered for. Using an OEM-specified pressure switch helps avoid callback issues that can arise from aftermarket parts with slightly different actuation points. This part suits service technicians who need a dependable, specification-matched component to restore boiler operation quickly and correctly.

• SPDT configuration supports both normally open and normally closed circuit monitoring
• Rated at 3.5 inches WC with a 0.44 inches WC reset point for precise pressure sensing
