{"product_id":"120-208","title":"120-208","description":"This professional-grade Air Pressure Switch is a vital safety component for residential and commercial heating systems. Designed as an air proving switch, it monitors the pressure within the draft inducer assembly to ensure the blower motor is creating sufficient airflow to vent combustion gases safely. With a calibrated set point of 1.60\" WC (Water Column), this switch acts as a critical safety interlock, preventing the furnace or boiler from igniting if venting issues or blockages are detected. This reliable replacement part is essential for troubleshooting heating systems that fail to ignite or display pressure switch-related error codes, restoring the safe and efficient operation of your HVAC equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC component size\u003cbr\u003e\nApplication: Forced-air gas furnaces, heating units, and HVAC systems requiring combustion air verification.\u003cbr\u003e\nSpecifications: 1.60\" WC (Water Column) trip point, air proving functionality, safety interlock mechanism","brand":"BCFurnace","offers":[{"title":"YORK\/ETC PRESSURESWITCH 1.60\"WC \/ 120-208","offer_id":50216793571613,"sku":null,"price":273.53,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC PRESSURESWITCH 1.60\"WC \/ S1-02425329706","offer_id":50216793604381,"sku":null,"price":273.53,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/72efe653d2854dda9022bad369041143.webp?v=1773964381","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-208","provider":"BCFurnace","version":"1.0","type":"link"}
