{"product_id":"040-377","title":"040-377","description":"The L210-20F High Limit Switch is a vital safety component for furnaces and HVAC heating systems, designed to provide reliable overheating protection. Functioning as a thermal cutout, this fan disc thermostat monitors internal air temperature and automatically breaks the electrical circuit if the system exceeds the 210°F safety threshold. This prevents damage to the heat exchanger and ensures safe operation of the appliance. Once the temperature drops by 20°F, the switch automatically resets to restore functionality. Replacing a faulty high-limit control is essential for maintaining proper airflow regulation and fire safety in residential and commercial forced-air heating units.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Commonly used in gas furnaces, electric heaters, and HVAC blower assemblies as a safety cutout to prevent equipment overheating.\u003cbr\u003e\nSpecifications: Cut-out temperature: 210°F; Temperature differential: 20°F (resets at 190°F); Automatic reset; Normally closed (NC) circuit configuration; Standard disc-style mounting.","brand":"BCFurnace","offers":[{"title":"Limit Switch\/Thermostat, L210-20F \/ 040-377","offer_id":50215666319645,"sku":null,"price":180.25,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch\/Thermostat, L210-20F \/ 338085-758","offer_id":50215666352413,"sku":null,"price":180.25,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/bb185165e3504bbdacba2d0c46fefee3.webp?v=1773967391","url":"https:\/\/bcfurnace.myshopify.com\/products\/040-377","provider":"BCFurnace","version":"1.0","type":"link"}
