{"product_id":"543-058","title":"543-058","description":"Ensure the safety and efficiency of your heating system with this 3-inch high limit switch. Designed as a critical safety component for gas furnaces and HVAC units, the L200-30F high limit control monitors internal temperatures to prevent the heat exchanger from overheating. When temperatures reach the 200°F threshold, the switch opens to interrupt the heating cycle, protecting your appliance and home. This thermal cutout switch features an automatic reset, closing again once the temperature drops by 30°F. If your furnace is frequently cycling off or failing to ignite, replacing a faulty or worn limit control is an essential repair for maintaining consistent airflow and safe operation. Engineered for durability and reliable performance in residential and commercial forced-air systems.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 3-inch\u003cbr\u003e\nDimensions: 3 inches (insertion depth)\u003cbr\u003e\nApplication: Used in residential gas furnaces, HVAC heating systems, and forced-air units to monitor plenum temperature and provide over-temperature protection.\u003cbr\u003e\nSpecifications: Temperature Rating: Opens at 200°F; Differential: 30°F (resets at 170°F); Switch Type: Normally Closed (NC); Reset Type: Automatic; 3-inch probe length.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ 543-058","offer_id":50932558823709,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ 025-29041-006","offer_id":50932558954781,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ 025-29041006","offer_id":50932558987549,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ 02529041-006","offer_id":50932559020317,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ 02529041006","offer_id":50932559085853,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ S1-025-29041-006","offer_id":50932558856477,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ S1-02529041-006","offer_id":50932558889245,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ S1-02529041006","offer_id":50932558922013,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-30F \/ S102529041006","offer_id":50932559053085,"sku":null,"price":152.43,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/9dd1d3dead27499f9594dff6ff269963.webp?v=1773966536","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-058","provider":"BCFurnace","version":"1.0","type":"link"}
