Designed as an auto-reset high limit control, it monitors internal temperatures to prevent equipment overheating and potential thermal damage. The switch is engineered with an L150-40F thermal profile, meaning it activates at 150°F and automatically resets once the temperature drops by 40°F. This fan disc style controller is a common solution for furnace repair and climate control maintenance, ensuring the appliance operates within safe parameters by either cutting power to heating elements or activating a cooling fan. Its SPDT configuration allows for versatile wiring options, making it an essential part for maintaining system reliability and household safety.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used as a safety limit or fan control in furnaces, air handlers, unit heaters, and various HVAC heating equipment.\u003cbr\u003e\nSpecifications: Circuit: SPDT (Single Pole Double Throw); Reset Type: Automatic; Open Temperature: 150°F; Differential: 40°F; Style: Disc Type","brand":"BCFurnace","offers":[{"title":"Limit Switch, Auto Reset, SPDT, L150-40F \/ 021-773","offer_id":50216324858141,"sku":null,"price":230.87,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch, Auto Reset, SPDT, L150-40F \/ CNT01031","offer_id":50216324890909,"sku":null,"price":230.87,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/3ac09bd2d5d84e57858ac00f5a8f68e6.webp?v=1773963012","url":"https:\/\/bcfurnace.myshopify.com\/products\/021-773","provider":"BCFurnace","version":"1.0","type":"link"}
