{"product_id":"543-042","title":"543-042","description":"Ensure your heating system operates safely with this 3-inch High Limit Switch. Designed as a critical safety cutoff for gas furnaces and HVAC units, this thermal sensor monitors the temperature within the heat exchanger to prevent overheating. The L160-20F model is engineered to trip and interrupt power to the burner if the internal temperature reaches 160 degrees Fahrenheit, protecting your equipment from heat-related damage and potential fire hazards. Once the unit cools by a 20-degree differential, the switch allows the system to resume normal operation. This high-limit control is a vital replacement part for maintaining furnace reliability and home safety in various forced-air heating applications.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 3-inch probe length\u003cbr\u003e\nDimensions: 3 inches\u003cbr\u003e\nApplication: Used in residential gas furnaces and forced-air heating systems to monitor heat exchanger temperatures and provide high-temperature safety protection.\u003cbr\u003e\nSpecifications: Trip Temperature: 160°F; Reset Differential: 20°F; Switch Configuration: Normally Closed (NC); Mounting: Flange mount with 3-inch insertion depth.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L160-20F \/ 543-042","offer_id":47251649986845,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L160-20F \/ 47-25349-01","offer_id":47251650117917,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L160-20F \/ 47-25350-05","offer_id":47251650019613,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L160-20F \/ 5931605","offer_id":47251650052381,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L160-20F \/ 6612230","offer_id":47251650085149,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/cda2ffc4ca0143068406cb83ed2d5117.webp?v=1773959135","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-042","provider":"BCFurnace","version":"1.0","type":"link"}
