{"product_id":"773-233","title":"773-233","description":"This professional-grade Rheem Air Pressure Switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. Functioning as an air proving switch with a precise 0.90\" WC (Water Column) set point, it monitors the negative pressure generated by the draft inducer motor. This ensures that the venting system is clear and the exhaust fan is operating correctly before the ignition sequence begins. If your heating system is failing to start or shuts down prematurely, a faulty pressure switch may be the culprit. Engineered for durability and reliable performance, this switch helps maintain the safety and operational integrity of your residential or commercial heating equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC Component\u003cbr\u003e\nApplication: Used in gas-fired furnaces and HVAC heating units to monitor inducer motor airflow and venting safety.\u003cbr\u003e\nSpecifications: 0.90\" WC (Water Column) pressure rating; Air proving function; Safety lockout integration.","brand":"BCFurnace","offers":[{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 773-233","offer_id":47251816382749,"sku":null,"price":114.11,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 42-24196-88","offer_id":47251816448285,"sku":null,"price":114.11,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH 0.90\" WC \/ 5931302","offer_id":47251816415517,"sku":null,"price":114.11,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/224e40d159c04df5a3e9f732dafcd4bf.webp?v=1773959340","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-233","provider":"BCFurnace","version":"1.0","type":"link"}
