{"product_id":"547-124","title":"547-124","description":"This 7-inch high limit switch is a vital safety component engineered for gas furnaces and forced-air heating systems. Designed to monitor the temperature within the heat exchanger, this thermal limit control acts as a safeguard against overheating. If the internal temperature reaches an unsafe threshold of 170°F, the switch automatically interrupts power to the burner or heating element, preventing equipment damage and ensuring home safety. Featuring a 30°F differential, the switch is designed to reset once the system cools to a safe operating temperature of 140°F. This replacement part is essential for HVAC repair when a furnace is short-cycling or failing to stay lit due to a faulty safety sensor.\u003cbr\u003e\nType: Furnace High Limit Safety Switch\u003cbr\u003e\nSize: 7-inch probe length\u003cbr\u003e\nDimensions: 7 inches\u003cbr\u003e\nApplication: Residential gas furnaces, forced-air heating units, and HVAC heat exchanger safety monitoring\u003cbr\u003e\nSpecifications: Trip Temperature: 170°F (L170); Reset Differential: 30°F (30F); Normally Closed configuration; 7-inch insertion depth","brand":"BCFurnace","offers":[{"title":"7\" HIGH LIMIT SWITCH L170-30F \/ 547-124","offer_id":47252025966877,"sku":null,"price":82.76,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L170-30F \/ 1370910S","offer_id":47252025999645,"sku":null,"price":82.76,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c71488d57a0c4f18b029c972ad665df4.webp?v=1773959912","url":"https:\/\/bcfurnace.myshopify.com\/products\/547-124","provider":"BCFurnace","version":"1.0","type":"link"}
