{"product_id":"762-073","title":"762-073","description":"The L140-30F Disc Limit Switch is a critical safety component designed for residential heating systems and furnaces. This high-limit control switch monitors the internal temperature of your HVAC equipment, acting as a thermal cutout to prevent overheating. When the temperature reaches its 140-degree Fahrenheit threshold, the switch opens the circuit to shut down the heating element or burner, protecting the appliance from damage. Once the unit cools down by the 30-degree differential, the auto-reset feature restores the connection, allowing for normal operation. This durable fan disc thermostat is a common replacement part for furnaces that are cycling improperly or failing to maintain safe operating temperatures.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: Small \/ Standard 3\/4-inch disc\u003cbr\u003e\nApplication: Used primarily in gas and electric furnaces, air handlers, and heating appliances as a safety limit or fan control.\u003cbr\u003e\nSpecifications: Temperature Rating: Open at 140°F; Differential: 30°F (Closes at 110°F); Reset Type: Automatic; Circuit: Normally Closed (NC); Mount Type: Surface mount flange.","brand":"BCFurnace","offers":[{"title":"DISC LIMIT SWITCH AUTO RESET L140-30F \/ 762-073","offer_id":47251378372893,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH AUTO RESET L140-30F \/ 1065294","offer_id":47251378405661,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH AUTO RESET L140-30F \/ 1149300","offer_id":47251378438429,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ff00a75ff91c4eb6ac71f2707c2f94f9.webp?v=1773958406","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-073","provider":"BCFurnace","version":"1.0","type":"link"}
