{"product_id":"762-093","title":"762-093","description":"The L120-20F Disc Limit Switch is a professional-grade thermal safety component designed for use in residential and commercial HVAC systems. This high-limit control switch plays a critical role in furnace safety by monitoring the temperature within the heat exchanger. Engineered to prevent overheating, the switch automatically opens the electrical circuit when the internal temperature reaches 120°F, shutting down the heating source. As an automatic reset model, it restores connectivity once the temperature drops by its 20°F differential (resetting at 100°F). This reliable fan disc switch is an essential replacement part for restoring the safety and efficiency of gas or electric furnaces and air handlers.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: Standard 3\/4-inch mounting disc\u003cbr\u003e\nDimensions: 0.75 in (disc diameter) × Not specified × Not specified\u003cbr\u003e\nApplication: Commonly used as a safety cutout or fan control in furnaces, air handlers, and various heating and cooling appliances.\u003cbr\u003e\nSpecifications: Opening Temperature: 120°F; Temperature Differential: 20°F; Reset Type: Automatic; Switch Logic: Open on Rise; Configuration: Fixed Temperature Disc","brand":"BCFurnace","offers":[{"title":"DISC LIMIT SWITCH AUTO RESET L120-20F \/ 762-093","offer_id":47251575570717,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH AUTO RESET L120-20F \/ 47-104465-02","offer_id":47251575603485,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH AUTO RESET L120-20F \/ 5931446","offer_id":47251575636253,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ff526b5618494af3889939786397dee8.webp?v=1773959028","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-093","provider":"BCFurnace","version":"1.0","type":"link"}
