{"product_id":"547-150","title":"547-150","description":"This 7-inch high limit switch is a vital safety component designed for residential and commercial heating systems, including furnaces and HVAC units. Functioning as a thermal safeguard, this control switch monitors the temperature within the heat exchanger or plenum. It is engineered to automatically interrupt the electrical circuit if temperatures reach a predetermined safety threshold of 150°F, preventing overheating and potential damage to the appliance. Once the system cools by 30°F, the switch resets to allow for normal operation. If your heating system is short-cycling or failing to provide consistent heat, a malfunctioning high limit sensor may be the cause. This durable replacement part ensures your furnace operates within safe temperature parameters, protecting your equipment and maintaining home safety.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 7-inch insertion length\u003cbr\u003e\nDimensions: 7 inches\u003cbr\u003e\nApplication: Used primarily in forced-air furnaces, HVAC systems, and high-capacity heating appliances as a primary safety limit control.\u003cbr\u003e\nSpecifications: Cut-out Temperature: 150°F; Differential\/Cut-in: 30°F; Automatic reset; Probe-style sensor.","brand":"BCFurnace","offers":[{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ 547-150","offer_id":47251386794269,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ 1NT21L-5056","offer_id":47251386827037,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ L150-30F...","offer_id":47251386859805,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L150-30F \/ THT02435","offer_id":47251386892573,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ddd6d274e0e74149af0df9715d2c4082.webp?v=1773958465","url":"https:\/\/bcfurnace.myshopify.com\/products\/547-150","provider":"BCFurnace","version":"1.0","type":"link"}
