{"product_id":"762-074","title":"762-074","description":"The DISC LIMIT SWITCH AUTO RESET L240-20F is a vital safety component for residential and commercial heating systems. Designed as a high-limit control, this fan disc switch monitors the internal temperature of furnaces and HVAC units to prevent hazardous overheating. When the ambient temperature reaches the 240-degree Fahrenheit threshold, the switch opens to break the electrical circuit, immediately shutting down the heat source. Once the system cools down by approximately 20 degrees, the auto-reset feature restores the connection for continued operation. This replacement part is essential for maintaining proper furnace cycling and protecting the heat exchanger from thermal damage. It is an ideal solution for fixing short-cycling issues or heating systems that have shut down due to high-temperature safety triggers.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Used in gas furnaces, electric heaters, and HVAC blower assemblies as a thermal safety cutout to prevent equipment damage and ensure fire safety.\u003cbr\u003e\nSpecifications: Cut-out Temperature: 240°F; Differential\/Reset: 20°F drop (resets at 220°F); Reset Type: Automatic; Contact Configuration: Normally Closed (NC).","brand":"BCFurnace","offers":[{"title":"DISC LIMIT SWITCH AUTO RESET L240-20F \/ 762-074","offer_id":47620762468637,"sku":null,"price":122.4,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH AUTO RESET L240-20F \/ 34335002","offer_id":47620762501405,"sku":null,"price":122.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/a0dd653c3eb243e0a8c829af9c099378.webp?v=1773967490","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-074","provider":"BCFurnace","version":"1.0","type":"link"}
