{"product_id":"543-049","title":"543-049","description":"Ensure the safety and efficiency of your heating system with this high-performance 3-inch High Limit Switch. This critical safety component is designed for residential furnaces and HVAC units to prevent the system from overheating. The L200-20F thermal control monitors the temperature of the heat exchanger, automatically opening the electrical circuit if the temperature reaches 200°F. It features a 20°F differential, meaning it will reset and restore power once the system cools to 180°F. Replacing a faulty limit sensor is essential for preventing short-cycling and protecting your furnace from internal damage. This reliable thermal cutout is a must-have for HVAC maintenance and furnace repair, providing peace of mind and consistent climate control.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 3-inch probe length\u003cbr\u003e\nDimensions: 3 in\u003cbr\u003e\nApplication: Used as a safety cutout in gas-fired furnaces, air handlers, and HVAC heating systems to monitor plenum temperatures.\u003cbr\u003e\nSpecifications: Temperature Limit: Opens at 200°F; Differential: 20°F (Closes at 180°F); Switch Type: Normally Closed (NC); Insertion Depth: 3 inches.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L200-20F \/ 543-049","offer_id":47251874349341,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-20F \/ 47-25349-05","offer_id":47251874382109,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L200-20F \/ 472534905","offer_id":47251874414877,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/dcd57795c77b4e5c980b4fcb09a61bf5.webp?v=1773959419","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-049","provider":"BCFurnace","version":"1.0","type":"link"}
