{"product_id":"762-042","title":"762-042","description":"This 3\/4-inch Disc Limit Switch is a vital thermal safety component designed for residential and commercial HVAC systems. Functioning as a high-limit control, this switch monitors internal temperatures within your furnace or air handler to prevent overheating. If the system exceeds its safe operating temperature, the switch automatically opens the electrical circuit to shut down the heating element or burner. Once the unit cools by the designated temperature differential, the automatic reset feature restores connectivity, ensuring continuous and safe operation of your heating equipment. This durable fan disc is an essential replacement part for maintaining the safety and efficiency of gas or electric furnaces.\u003cbr\u003e\nType: Fan Disc \/ High Limit Control Switch\u003cbr\u003e\nSize: 3\/4 Inch\u003cbr\u003e\nDimensions: 0.75 in (Disc Diameter) × unknown × unknown\u003cbr\u003e\nApplication: Commonly used in gas and electric furnaces, air handlers, and HVAC equipment as a safety cut-off or fan control switch.\u003cbr\u003e\nSpecifications: Open Temperature: 170°F; Temperature Differential: 20°F (Resets at 150°F); Reset Type: Automatic; Contact Action: Normally Closed (NC) until temperature threshold is reached.","brand":"BCFurnace","offers":[{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L170-20F \/ 762-042","offer_id":47251350749469,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L170-20F \/ 1184422","offer_id":47251350847773,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L170-20F \/ 338096-702","offer_id":47251350782237,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L170-20F \/ L170-20F","offer_id":47251350815005,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/30efdd8605024bd292f09ed2ff7241ca.webp?v=1773958347","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-042","provider":"BCFurnace","version":"1.0","type":"link"}
