{"product_id":"762-502","title":"762-502","description":"This professional-grade 3\/4-inch disc fan switch is a critical component for regulating airflow in heating systems and HVAC equipment. Designed as an automatic reset thermal control, this switch monitors the temperature within the furnace plenum or heat exchanger to cycle the blower fan on and off efficiently. By ensuring the fan only operates when the air is sufficiently warm and shutting it down once the system cools, it maximizes energy efficiency and prevents the circulation of cold air. The durable bimetal disc construction provides reliable, long-lasting performance, making it an ideal replacement part for restoring proper ventilation and preventing overheating in residential and light commercial heating units.\u003cbr\u003e\nType: Fan Disc Control Switch\u003cbr\u003e\nSize: 3\/4\" Disc\u003cbr\u003e\nDimensions: 0.75 in\u003cbr\u003e\nApplication: Forced-air furnaces, electric heaters, HVAC blower motors, and air handling units.\u003cbr\u003e\nSpecifications: Automatic reset; Fan logic: Closes on temperature rise at 110°F and opens on temperature fall with a 20°F differential (at 90°F); SPST (Single Pole Single Throw) circuitry.","brand":"BCFurnace","offers":[{"title":"FAN SWITCH 3\/4\" DISC AUTO RESET F110-20F \/ 762-502","offer_id":49602556035357,"sku":null,"price":21.17,"currency_code":"CAD","in_stock":true},{"title":"FAN SWITCH 3\/4\" DISC AUTO RESET F110-20F \/ 3F01-110","offer_id":49293596918045,"sku":null,"price":21.17,"currency_code":"CAD","in_stock":true},{"title":"FAN SWITCH 3\/4\" DISC AUTO RESET F110-20F \/ 3F01110","offer_id":49293596885277,"sku":null,"price":21.17,"currency_code":"CAD","in_stock":true},{"title":"FAN SWITCH 3\/4\" DISC AUTO RESET F110-20F \/ F110-20F","offer_id":49293596852509,"sku":null,"price":21.17,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/3e8048b355fd4ddb9d452312a00eb823.webp?v=1773960631","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-502","provider":"BCFurnace","version":"1.0","type":"link"}
