{"product_id":"773-038","title":"773-038","description":"Ensure your heating system operates safely and efficiently with this high-quality 2-stage air pressure switch. Specifically engineered for dual-stage gas furnaces, this air-proving switch acts as a critical safety component by monitoring the negative pressure generated by the inducer fan motor. It ensures that the furnace has proper venting and combustion airflow before allowing the ignition process to begin. With calibrated set points of -0.60\" WC and -0.35\" WC, this switch helps maintain peak performance in multi-stage HVAC systems. This is an essential replacement part for resolving common furnace issues such as ignition failure, venting errors, or pressure switch lockout codes.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: High-efficiency two-stage gas furnaces and HVAC heating systems.\u003cbr\u003e\nSpecifications: Dual-stage operation; Low-stage set point: -0.35\" WC; High-stage set point: -0.60\" WC; Type: Air Proving\/Safety Switch.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 773-038","offer_id":47251070058781,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 103271-02","offer_id":47251070157085,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 103613-02","offer_id":47251070189853,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 104549-02","offer_id":47251070124317,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 14A44","offer_id":47251070091549,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 84W06","offer_id":47251070222621,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG -0.60\" WC \/ -0.35\" WC \/ 93W78","offer_id":47251070255389,"sku":null,"price":172.47,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/113b44426bf441199d050345fbcf91a3.webp?v=1773967116","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-038","provider":"BCFurnace","version":"1.0","type":"link"}
