{"product_id":"547-190","title":"547-190","description":"This professional-grade 7-inch high limit control switch is a vital safety component designed for heating systems, furnaces, and HVAC units. Functioning as a thermal safeguard, it continuously monitors internal temperatures to prevent overheating and potential equipment damage. When the system reaches a critical temperature threshold, the switch interrupts the electrical circuit, automatically resetting once the unit has cooled down by its designated differential. This high-reliability thermal cut-out is essential for maintaining optimal airflow and temperature regulation in residential and commercial air handling equipment. It is a common replacement part for troubleshooting short-cycling heating units and ensuring the long-term safety and efficiency of your climate control system.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 7-inch probe length\u003cbr\u003e\nDimensions: 7 inches\u003cbr\u003e\nApplication: HVAC systems, residential and commercial furnaces, air handlers, and forced-air heating units.\u003cbr\u003e\nSpecifications: Cut-out Temperature: 190°F; Reset Differential: 30°F; Automatic reset; Normally closed circuit configuration.","brand":"BCFurnace","offers":[{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ 547-190","offer_id":47251364938013,"sku":null,"price":90.13,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ 65208400","offer_id":47251365036317,"sku":null,"price":90.13,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ 86H72","offer_id":47251364970781,"sku":null,"price":90.13,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ 86H7201","offer_id":47251365003549,"sku":null,"price":90.13,"currency_code":"CAD","in_stock":true},{"title":"7\" HIGH LIMIT SWITCH L190-30F \/ L190-30F...","offer_id":47251365069085,"sku":null,"price":90.13,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/b64736fbf7f54549b9ccc80139399b65.webp?v=1773958378","url":"https:\/\/bcfurnace.myshopify.com\/products\/547-190","provider":"BCFurnace","version":"1.0","type":"link"}
