{"product_id":"547-122","title":"547-122","description":"The 7-inch High Limit Switch L190-30F is a critical safety component designed for modern heating systems and HVAC equipment. This thermal limit control acts as a vital safeguard, monitoring internal temperatures to prevent your furnace or heating unit from overheating. If the temperature reaches its 190°F threshold, the switch automatically opens to break the electrical circuit, protecting the appliance from heat damage and ensuring safe operation. With a 30°F differential, the switch is engineered to reset once the system cools to a safe level. This reliable sensor is a common replacement part for residential and commercial furnaces where precise temperature regulation and safety are paramount.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 7-inch probe depth\u003cbr\u003e\nDimensions: 7 in\u003cbr\u003e\nApplication: Used primarily in gas and electric furnaces, HVAC units, and heating appliances to monitor internal plenum temperatures and provide over-temperature protection.\u003cbr\u003e\nSpecifications: Cut-out temperature: 190°F; Differential: 30°F; Configuration: Normally Closed (NC) - Opens on Rise; Probe length: 7 inches.","brand":"BCFurnace","offers":[{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ 547-122","offer_id":47252072202525,"sku":null,"price":169.89,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ SWT 03031","offer_id":47252072268061,"sku":null,"price":169.89,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ SWT03031","offer_id":47252072235293,"sku":null,"price":169.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d0f61581799c4a759b337f3403cefcb7.webp?v=1773960108","url":"https:\/\/bcfurnace.myshopify.com\/products\/547-122","provider":"BCFurnace","version":"1.0","type":"link"}
