{"product_id":"773-121","title":"773-121","description":"This high-quality York Pressure Switch is a vital safety and performance component for residential and commercial heating systems. As a precision air proving switch, it monitors the pressure differential generated by the draft inducer blower, ensuring that the ventilation system is clear and the motor is operational before the furnace is allowed to ignite. Calibrated with a 1.00\" WC (Water Column) set point, this switch prevents hazardous operation in the event of a blocked flue, restricted intake, or mechanical failure. If your furnace is failing to start or displaying a pressure switch lockout code, this reliable replacement part is essential for restoring safe and efficient HVAC performance. It is designed for durability and consistent sensing in demanding heating applications.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC component\u003cbr\u003e\nApplication: Designed for use in forced-air furnaces and HVAC systems to verify proper airflow and venting pressure before ignition.\u003cbr\u003e\nSpecifications: 1.00\" WC (Water Column) trip point, air proving safety function, compatible with negative and positive pressure sensing.","brand":"BCFurnace","offers":[{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 773-121","offer_id":49602274558237,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 024-27638-001","offer_id":49602274754845,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 02427638001","offer_id":49602274787613,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 024-35261-000","offer_id":49602274820381,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 02435261000","offer_id":49602274591005,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 106122","offer_id":49602274689309,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ 9371DO-HS-0010","offer_id":49602274853149,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ S1-024-27638-001","offer_id":49602274623773,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ S1-02427638001","offer_id":49602274722077,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ S1-024-35261-000","offer_id":49602274656541,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH 1.00\" WC \/ S1-02435261000","offer_id":49602274885917,"sku":null,"price":164.51,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/cbc6879e842c4788b509ab79b06b9039.webp?v=1773967210","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-121","provider":"BCFurnace","version":"1.0","type":"link"}
