{"product_id":"120-630","title":"120-630","description":"The York Fan Limit L170-60F is a high-performance safety and operational control designed for forced-air heating systems. This fan limit switch plays a critical role in furnace maintenance by monitoring the temperature within the heat exchanger. It functions as a dual-purpose sensor: it regulates the blower motor's cycle to ensure efficient heat distribution and serves as a high-limit safety cut-out. If the internal furnace temperature reaches the 170°F threshold, the switch automatically interrupts the heating circuit to prevent overheating and potential equipment damage. Once the system cools by the designated 60°F differential, it allows for safe operation to resume. This part is essential for HVAC repair when a furnace fan fails to start, runs continuously, or if the unit is short-cycling due to a faulty limit sensor.\u003cbr\u003e\nType: Fan Limit Switch\u003cbr\u003e\nSize: Standard furnace control component\u003cbr\u003e\nApplication: Commonly used in residential and commercial furnaces, air handlers, and heating units to control blower fan timing and provide high-temperature safety protection.\u003cbr\u003e\nSpecifications: High-limit trip temperature: 170°F; Fan differential: 60°F; SPST or SPDT configuration depending on wiring; Automatic reset functionality.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC FAN LIMIT L170 60F \/ 120-630","offer_id":50216914059549,"sku":null,"price":84.87,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC FAN LIMIT L170 60F \/ S1-02526366003","offer_id":50216914092317,"sku":null,"price":84.87,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ae3f21924bd7438dbb1101b42e0a7a28.webp?v=1773964477","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-630","provider":"BCFurnace","version":"1.0","type":"link"}
