{"product_id":"120-658","title":"120-658","description":"The York\/ETC High Limit Control Switch is a vital safety component designed for residential and commercial heating systems. This fan disc-style switch acts as a thermal safeguard for your furnace or air handler, monitoring internal temperatures to prevent overheating. Engineered to open the electrical circuit when the system reaches 230°F, it effectively shuts down the heating element to protect the appliance from damage and ensure home safety. Once the temperature drops by the 30°F differential, the switch resets, allowing the unit to resume normal operation. If your furnace is short-cycling or failing to heat, a worn-out limit switch may be the cause. This high-quality replacement part ensures your HVAC system maintains peak efficiency and reliable temperature regulation.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard small-format thermal disc\u003cbr\u003e\nApplication: Used primarily as a safety cut-out in gas furnaces, electric heaters, and air handling units to prevent heat exchanger damage.\u003cbr\u003e\nSpecifications: Opening Temperature: 230°F; Closing Temperature: 200°F (30°F differential); Automatic reset; Two-terminal connection.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC LIMIT SWITCH L230-30F \/ 120-658","offer_id":50216932016413,"sku":null,"price":100.46,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC LIMIT SWITCH L230-30F \/ S1-02529041013","offer_id":50216932049181,"sku":null,"price":100.46,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/1f1c8fd102084400b2c73412b6f8c030.webp?v=1773964601","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-658","provider":"BCFurnace","version":"1.0","type":"link"}
