{"product_id":"547-126","title":"547-126","description":"The 7-inch High Limit Switch L150-30F is a vital safety component for residential gas furnaces and HVAC heating systems. Designed to monitor the internal temperature of the heat exchanger, this limit control switch acts as a failsafe by automatically interrupting the heating cycle if the unit reaches an unsafe temperature. Featuring a 7-inch probe for accurate air temperature sensing, this thermal switch ensures your heating system operates within safe parameters, preventing components from sustaining damage due to overheating. Common signs that a high limit switch needs replacement include the furnace blower fan running continuously or the heating system short-cycling. This durable, automatic-reset switch provides a reliable solution for maintaining optimal temperature regulation in central forced-air heating applications.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 7-inch probe length\u003cbr\u003e\nDimensions: 7 inches (insertion depth)\u003cbr\u003e\nApplication: Residential gas furnaces, forced-air heating systems, and HVAC units requiring overheat protection and temperature regulation.\u003cbr\u003e\nSpecifications: Temperature Limit: Opens at 150°F; Differential: 30°F (Closes at 120°F); Reset Type: Automatic; Sensor Type: Insertion probe.","brand":"BCFurnace","offers":[{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ 547-126","offer_id":47250996953373,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ 1370906S","offer_id":47250996986141,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/14376367922e4732815166e67f0e3820.webp?v=1773957171","url":"https:\/\/bcfurnace.myshopify.com\/products\/547-126","provider":"BCFurnace","version":"1.0","type":"link"}
