{"product_id":"762-112","title":"762-112","description":"This premium L155-40F Auto Reset Disc Limit Switch is an essential safety component for residential heating systems and HVAC equipment. Designed to function as a high-limit control, this bimetal disc switch monitors the internal temperature of your furnace or air handler to prevent overheating. When the system reaches the pre-set temperature of 155°F, the switch opens the circuit to safely shut down the heating element or burner. As an auto-resetting model, it automatically closes the circuit once the temperature drops by 40°F, allowing your unit to resume normal operation without manual intervention. Replacing a faulty or worn limit switch is crucial for maintaining the safety, efficiency, and longevity of your forced-air heating system.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard bimetal disc size\u003cbr\u003e\nApplication: Used primarily in forced-air furnaces, air handlers, and HVAC heating systems as a safety cut-off and temperature regulation device.\u003cbr\u003e\nSpecifications: Temperature Open: 155°F; Temperature Close: 115°F (40°F differential); Reset Type: Automatic; Circuit: Normally Closed (NC)","brand":"BCFurnace","offers":[{"title":"DISC LIMIT SWITCH, AUTO RESET L155-40F \/ 762-112","offer_id":47251907084573,"sku":null,"price":65.8,"currency_code":"CAD","in_stock":true},{"title":"DISC LIMIT SWITCH, AUTO RESET L155-40F \/ 626470R","offer_id":47251907117341,"sku":null,"price":65.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/21729ba25b6f45b89d1d77dfc60a9864.webp?v=1773959499","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-112","provider":"BCFurnace","version":"1.0","type":"link"}
