{"product_id":"762-078","title":"762-078","description":"This 3\/4\" bimetal disc limit switch is an essential safety component for residential and commercial HVAC systems, including furnaces and air handlers. Functioning as a high-limit control, it monitors the internal temperature of your heating equipment to prevent overheating and potential damage. The switch is designed to automatically trip and open the circuit when temperatures reach 155°F, effectively shutting down the heat source. Once the temperature cools by 40°F, the auto-reset feature restores the electrical connection, allowing for seamless and safe operation. This reliable thermal sensor is a standard replacement part for maintaining the performance and safety standards of modern forced-air heating systems.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: 3\/4 inch\u003cbr\u003e\nApplication: Commonly installed in furnaces, air handlers, and forced-air heating units to provide thermal protection and high-limit temperature monitoring.\u003cbr\u003e\nSpecifications: Open Temperature: 155°F; Reset Differential: 40°F (Closes at 115°F); Reset Type: Automatic; Sensor Type: Bimetal Disc","brand":"BCFurnace","offers":[{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L155-40F \/ 762-078","offer_id":47251455770909,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L155-40F \/ 025-47296-000","offer_id":47251455869213,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L155-40F \/ 02547296000","offer_id":47251455901981,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L155-40F \/ S1-025-47296-000","offer_id":47251455836445,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L155-40F \/ S1-02547296000","offer_id":47251455803677,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/4e51ca0166cc4c479545d616efbfd693.webp?v=1773967302","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-078","provider":"BCFurnace","version":"1.0","type":"link"}
