{"product_id":"773-305","title":"773-305","description":"This premium two-stage air pressure switch is a vital safety component designed for high-efficiency gas furnaces. As an essential air proving switch, its primary function is to monitor the negative pressure created by the draft inducer motor, ensuring that combustion gases are being safely exhausted through the flue before allowing the furnace ignition sequence to begin. If your heating system is failing to start or is cycling off prematurely, a faulty pressure switch is often the culprit. This dual-stage switch features two distinct set points to accommodate varying blower speeds, providing precise monitoring for both low-fire and high-fire heating cycles. Engineered for reliability and durability, this component helps maintain the safety, efficiency, and proper operation of your residential HVAC system.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in multi-stage gas furnaces and HVAC heating systems to monitor venting pressure and ensure proper inducer motor operation.\u003cbr\u003e\nSpecifications: Two-stage dual-setpoint operation; Stage 1 calibrated to -0.45\" WC; Stage 2 calibrated to -0.85\" WC; vacuum-actuated safety interlock.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.45\" WC \/ -0.85\" WC \/ 773-305","offer_id":47251227181341,"sku":null,"price":96.16,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.45\" WC \/ -0.85\" WC \/ 0130F00501","offer_id":47251227214109,"sku":null,"price":96.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c1d4c58574fc48fc9ae7dc23c9883343.webp?v=1773957839","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-305","provider":"BCFurnace","version":"1.0","type":"link"}
