It is a single-pole double-throw (SPDT) switch rated at 0.5 inches water column (WC). This component plays a critical role in the safe operation of induced-draft and forced-draft boilers. The switch monitors the negative pressure created by the draft inducer motor. If the inducer fails to produce the correct airflow, the switch prevents the burner from firing. This protects the system from operating under unsafe flue gas conditions. HVAC technicians rely on this type of pressure switch during routine maintenance, diagnostics, and component replacement. The barb fitting connection makes installation straightforward and compatible with standard pressure tubing used in most boiler setups. The SPDT configuration allows the switch to break one circuit and make another simultaneously, giving the boiler control board accurate feedback on draft status. A faulty or out-of-calibration pressure switch is a common cause of boiler lockout codes. Replacing the switch with a correctly rated OEM-spec unit like the 1401003 restores reliable ignition sequencing. This part is specific to Utica Boilers and Dunkirk heating equipment, both of which share a product platform under the same manufacturing group. Technicians should verify the set point and fitting size before installation to confirm compatibility with the target unit. The 0.5 inches WC set point is a common rating found in many residential boiler models. Keeping this switch in stock reduces downtime during heating season service calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSPDT air pressure switch rated at 0.5 inches water column for accurate draft proving\u003c\/li\u003e\n\u003cli\u003eBarb fitting connection for easy tubing attachment during field installation\u003c\/li\u003e\n\u003cli\u003eCompatible with Utica Boilers and Dunkirk induced-draft and forced-draft heating systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Utica Boilers 1401003 air pressure switch provides reliable draft proving at a 0.5 inches WC set point, helping technicians restore safe boiler operation quickly and with confidence.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UTICA BOILERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1401003\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPDT (Single-Pole Double-Throw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Point\u003c\/strong\u003e: 0.5 inches WC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Barb Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Induced-Draft and Forced-Draft Boilers\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UTICA BOILERS","offers":[{"title":"Default Title","offer_id":51120793747762,"sku":"1401003","price":56.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304882558.jpg?v=1777739876","url":"https:\/\/voomisupply.com\/products\/utica-boilers-1401003-air-pressure-switch-spdt-0-5-inches-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
