{"product_id":"120-656","title":"120-656","description":"The York L170 Manual Reset High Limit Switch is an essential safety component designed for residential and commercial forced-air furnaces and HVAC systems. This high-limit control acts as a critical safeguard by monitoring the temperature within the heat exchanger. If the system exceeds a safe operating temperature of 170°F—often caused by restricted airflow, a dirty filter, or a failing blower motor—the switch automatically breaks the electrical circuit to shut down the heating elements or burners. As a manual reset thermal disc, it ensures that the system cannot restart until a technician or user has inspected the unit and physically reset the switch, preventing repetitive overheating and potential equipment damage. Durable and reliable, this fan disc style switch is a standard replacement part for maintaining the safety and efficiency of your heating equipment.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard HVAC residential\/commercial size\u003cbr\u003e\nDimensions: unknown × unknown × unknown\u003cbr\u003e\nApplication: Forced-air furnaces, gas-fired heating units, and HVAC air handlers requiring a high-temperature safety cutout.\u003cbr\u003e\nSpecifications: Cut-out temperature: 170°F; Reset type: Manual; Contact action: Normally closed (opens on temperature rise); Mounting: Flange mount for surface sensing.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC LIMIT SWITCH L170 MANUALRESET \/ 120-656","offer_id":50216931819805,"sku":null,"price":89.19,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC LIMIT SWITCH L170 MANUALRESET \/ S1-02527792708","offer_id":50216931852573,"sku":null,"price":89.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/a9c3670d7bd04cde9abca379739be6a7.webp?v=1773964591","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-656","provider":"BCFurnace","version":"1.0","type":"link"}
