{"product_id":"773-219","title":"773-219","description":"This high-performance air pressure switch is a critical safety component for residential gas furnaces and high-efficiency heating systems. Functioning as an air-proving sensor, it monitors the pressure differential generated by the inducer blower motor to ensure the exhaust system is venting combustion gases safely. Rated at 0.90\" WC (Water Column), this switch is designed to prevent the ignition sequence if a flue blockage or mechanical failure is detected, protecting your home from potential hazards. It is a common replacement part for HVAC systems experiencing startup issues, intermittent heating cycles, or pressure-related error codes. Engineered for precision and reliability, this switch helps maintain the efficiency and safety of your gas-fired heating equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Commonly used in residential gas furnaces and high-efficiency HVAC units to verify inducer motor draft and ensure proper venting of exhaust gases before ignition.\u003cbr\u003e\nSpecifications: Pressure Rating: 0.90\" WC (Water Column); Function: Air Proving and Draft Verification; Application: Gas-fired heating systems.","brand":"BCFurnace","offers":[{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 773-219","offer_id":50509971128605,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 42-102070-11","offer_id":50509971194141,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 42-105583-08","offer_id":50509971259677,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 5930782","offer_id":50509971292445,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 5934654","offer_id":50509971161373,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ PD425152","offer_id":50509971226909,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/12754f78121a4db88702b01e380a809e.webp?v=1773959435","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-219","provider":"BCFurnace","version":"1.0","type":"link"}
