{"product_id":"773-061","title":"773-061","description":"Ensure your heating system operates safely and efficiently with this premium dual-stage furnace air pressure switch. Specifically engineered for two-stage gas furnaces, this air proving switch serves as a vital safety mechanism that monitors the draft produced by the inducer blower motor. By verifying that combustion gases are being properly vented, it prevents the furnace from ignition if an airflow obstruction or blower failure is detected. With calibrated set points of 0.20\" WC and 0.35\" WC, this switch is designed to handle the variable air pressures associated with multi-stage heating cycles. It is an essential replacement part for resolving common furnace issues such as failure to ignite, frequent cycling, or pressure switch lockout codes. Built for durability and precise response, this technical component maintains the reliable performance of your residential HVAC system.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used in residential two-stage gas furnaces to verify proper venting and inducer motor operation.\u003cbr\u003e\nSpecifications: Dual-stage (2-STG) functionality; Set points: 0.20\" WC (Water Column) and 0.35\" WC; Type: Air Proving Switch","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH 2-STG 0.20\" WC \/ 0.35\" WC \/ 773-061","offer_id":47251209683229,"sku":null,"price":120.64,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG 0.20\" WC \/ 0.35\" WC \/ 102529-02","offer_id":47251209814301,"sku":null,"price":120.64,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG 0.20\" WC \/ 0.35\" WC \/ 18M64","offer_id":47251209748765,"sku":null,"price":120.64,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG 0.20\" WC \/ 0.35\" WC \/ 18M6401","offer_id":47251209781533,"sku":null,"price":120.64,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 2-STG 0.20\" WC \/ 0.35\" WC \/ 63W41","offer_id":47251209715997,"sku":null,"price":120.64,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d8ca5d4237d04e1e93405323b7c964ff.webp?v=1773957825","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-061","provider":"BCFurnace","version":"1.0","type":"link"}
