{"product_id":"001-060","title":"001-060","description":"The Lennox L170-40F Blue Label High Limit Switch is a critical safety component designed for furnace and HVAC systems. This fan disc style control switch acts as a fail-safe by monitoring the internal temperature of the heat exchanger. If the system exceeds a safe operating temperature of 170°F, the switch automatically interrupts power to prevent overheating and potential equipment damage. Once the temperature cools by the 40°F differential, the circuit resets. This high-quality replacement part is essential for maintaining the safe operation of residential and commercial heating units. If your furnace is short-cycling or failing to provide consistent heat, a faulty high-limit sensor may be the issue.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used as a safety cutout in furnaces, air handlers, and rooftop HVAC units to protect against overheating.\u003cbr\u003e\nSpecifications: Temperature Rating: L170-40F (Opens at 170°F, 40°F differential); Blue Label identifier; 2-pin terminal connection; Fan disc configuration.","brand":"BCFurnace","offers":[{"title":"LENNOX LIMIT SWITCH L170-40F, BLUE LABEL \/ 001-060","offer_id":50215947108637,"sku":null,"price":36.67,"currency_code":"CAD","in_stock":true},{"title":"LENNOX LIMIT SWITCH L170-40F, BLUE LABEL \/ 75M31","offer_id":50215947141405,"sku":null,"price":36.67,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/33be0edd7f7144fcaa8f24f37d601c67.webp?v=1773965833","url":"https:\/\/bcfurnace.myshopify.com\/products\/001-060","provider":"BCFurnace","version":"1.0","type":"link"}
