{"product_id":"543-016","title":"543-016","description":"Ensure your heating system operates safely and efficiently with this premium high limit control switch. Designed as a critical safety mechanism for forced-air furnaces and HVAC units, this thermal sensor monitors the temperature within the heat exchanger. If internal temperatures reach a dangerous level, the switch automatically interrupts the burner circuit to prevent overheating and potential equipment damage. It features a precise 230-degree Fahrenheit cutout point and a 30-degree reset differential to ensure your system returns to operation only when it has cooled to a safe temperature. This 3-inch limit control is a vital replacement part for addressing common furnace issues like short-cycling or a blower motor that runs constantly due to a tripped safety circuit.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 3-inch insertion\u003cbr\u003e\nDimensions: 3 inches\u003cbr\u003e\nApplication: Residential gas furnaces, electric heating systems, and forced-air HVAC units requiring thermal overload protection.\u003cbr\u003e\nSpecifications: Cut-out temperature: 230°F; Cut-in\/Reset temperature: 200°F (30°F differential); Normally closed circuit; 3-inch flange-to-tip depth.","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L230-30F \/ 543-016","offer_id":47251351109917,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L230-30F \/ C340366P08","offer_id":47251351208221,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L230-30F \/ L230-30F","offer_id":47251351240989,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L230-30F \/ SWT01652","offer_id":47251351142685,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L230-30F \/ SWT1652","offer_id":47251351175453,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/98d60b66f2f8426cbef6674445b5b8fa.webp?v=1773967254","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-016","provider":"BCFurnace","version":"1.0","type":"link"}
