{"product_id":"773-238","title":"773-238","description":"This Rheem Air Pressure Switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. As an essential air-proving switch, it monitors the pressure within the inducer motor assembly to ensure proper venting of combustion gases. If the furnace detects insufficient airflow or a blocked vent, this switch prevents the ignition sequence, protecting your home and equipment. Replacing a faulty pressure switch is a common fix for furnaces that fail to ignite, inducer motors that run without the burner lighting, or systems that shut down mid-cycle due to airflow errors. This precision-calibrated switch ensures your heating system operates reliably and safely during the cold weather months.\u003cbr\u003e\nType: Air Pressure Switch \/ Air Proving Switch\u003cbr\u003e\nSize: Standard HVAC component\u003cbr\u003e\nDimensions: Not specified × Not specified × Not specified\u003cbr\u003e\nApplication: Used in gas-fired furnaces and heating equipment to monitor combustion blower pressure and ensure safe exhaust venting.\u003cbr\u003e\nSpecifications: Dual-point pressure ratings: -1.15\" WC (Water Column) \/ -0.98\" WC.","brand":"BCFurnace","offers":[{"title":"RHEEM PRESSURE SWITCH -1.15\" WC \/ -0.98\" WC \/ 773-238","offer_id":50509930070301,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"RHEEM PRESSURE SWITCH -1.15\" WC \/ -0.98\" WC \/ 42-106242-05","offer_id":50509930103069,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ae653b7695184c7dabda5016b03c3a91.webp?v=1773959287","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-238","provider":"BCFurnace","version":"1.0","type":"link"}
