{"product_id":"762-023","title":"762-023","description":"The 3\/4\" Disc High Limit Switch is a vital safety component designed for HVAC systems and heating appliances. This automatic reset thermal control monitors temperatures to prevent equipment overheating and potential damage. When the surface temperature reaches the 140°F limit, the switch opens the electrical circuit to cut power to the heating element or fan. Once the unit cools down by 40°F, it automatically resets, restoring normal operation without manual intervention. This durable fan disc switch is an essential replacement part for maintaining the safety and efficiency of furnaces, heaters, and other forced-air applications.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: 3\/4 inch disc diameter\u003cbr\u003e\nDimensions: 0.75 in\u003cbr\u003e\nApplication: Commonly used in residential furnaces, electric heaters, air handlers, and clothes dryers to provide thermal protection and fan control.\u003cbr\u003e\nSpecifications: Cut-out temperature: 140°F; Reset temperature: 100°F (40°F differential); Switch configuration: Normally Closed (NC); Automatic reset; 3\/4\" flanged mount.","brand":"BCFurnace","offers":[{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 762-023","offer_id":47250977128733,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 3L01-140","offer_id":47250977161501,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 3L01140","offer_id":47250977227037,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 3L140","offer_id":47250977292573,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ L140-40F","offer_id":47250977194269,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/f0f74c2f26ef4e47bdfcbc7a1ff75d57.webp?v=1773957059","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-023","provider":"BCFurnace","version":"1.0","type":"link"}
