{"product_id":"543-035","title":"543-035","description":"The 3-inch High Limit Switch L190-20F is a vital safety component designed for HVAC systems, gas furnaces, and electric heating appliances. This thermal cutout switch acts as a failsafe, monitoring the internal temperature of your equipment to prevent overheating. When the ambient temperature reaches the fixed set point of 190°F, the switch opens the electrical circuit to shut down the heating element or burner, protecting the appliance from damage and ensuring home safety. Featuring a 20°F differential, the switch automatically resets once the temperature drops, allowing for continued operation. This durable high-limit thermostat is an essential replacement part for maintaining the reliability and efficiency of residential and commercial heating units.\u003cbr\u003e\nType: High Limit Thermostat Control Switch\u003cbr\u003e\nSize: 3-inch insertion depth\u003cbr\u003e\nDimensions: 3 inches\u003cbr\u003e\nApplication: Commonly used in forced air furnaces, unit heaters, HVAC air handlers, and clothes dryers to provide over-temperature protection.\u003cbr\u003e\nSpecifications: Cut-out temperature: 190°F; Differential\/Reset: 20°F; Configuration: Normally Closed (NC); Mount type: Flange mount","brand":"BCFurnace","offers":[{"title":"3\" HIGH LIMIT SWITCH L190-20F \/ 543-035","offer_id":47251449413917,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L190-20F \/ 3L09-9","offer_id":47251449446685,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L190-20F \/ 3L099","offer_id":47251449544989,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true},{"title":"3\" HIGH LIMIT SWITCH L190-20F \/ L190-20F","offer_id":47251449479453,"sku":null,"price":68.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/a78f2cafaa744866bff2c2eb0b139853.webp?v=1773958730","url":"https:\/\/bcfurnace.myshopify.com\/products\/543-035","provider":"BCFurnace","version":"1.0","type":"link"}
