{"product_id":"543-046","title":"543-046","description":"The 3-inch High Limit Switch (L200-20F) is a vital safety component designed for residential and commercial HVAC heating systems. This thermal limit control acts as a protective sensor, monitoring the temperature within the furnace heat exchanger. It is engineered to automatically interrupt the electrical circuit and shut down the burner if the internal temperature exceeds a safe threshold of 200°F, preventing potential damage to the unit and ensuring home safety. Featuring a 20°F differential, the switch resets once the system cools to 180°F. If your furnace is short-cycling or the blower motor continues to run without heat, this high-quality replacement limit switch is a primary troubleshooting component for restoring reliable performance and overheating protection.\u003cbr\u003e\nType: Furnace High Limit Safety Control\u003cbr\u003e\nSize: 3-inch insertion depth\u003cbr\u003e\nDimensions: 3 inches\u003cbr\u003e\nApplication: Commonly used in gas furnaces, electric heating units, and forced-air HVAC systems as a primary safety limit or blower motor control.\u003cbr\u003e\nSpecifications: Temperature Rating: L200-20F (Opens at 200°F, Closes at 180°F); 20°F fixed differential; features a 3-inch probe for heat sensing.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L200-20F \/ 543-046","offer_id":47251550929181,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-20F \/ 47-25350-09","offer_id":47251550961949,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/a487af6da180405faa32debb49b44d14.webp?v=1773958988","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-046","provider":"BCFurnace","version":"1.0","type":"link"}
