{"product_id":"120-939","title":"120-939","description":"This automatic reset high limit control switch is a critical safety component designed for HVAC systems and forced-air furnaces. Functioning as a fan disc thermal cutout, this switch monitors the internal temperature of your heating equipment to prevent overheating. When the temperature reaches the pre-set high limit of 130°F, the switch automatically opens the circuit to shut down the burner or heating element, protecting the appliance from heat damage. Once the system cools back down to 100°F, the switch resets itself to restore normal operation. This durable, snap-action disc switch is essential for maintaining safe operating temperatures and extending the lifespan of residential and commercial heating units.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard Fan Disc\u003cbr\u003e\nApplication: Commonly used in furnaces, air handlers, and HVAC heating systems as a safety limit or fan control device.\u003cbr\u003e\nSpecifications: Open Temperature: 130°F; Close Temperature: 100°F; Reset Type: Automatic; Configuration: Normally Closed (NC)","brand":"BCFurnace","offers":[{"title":"SWITCH,LIMIT,100\/130,AUTO \/ 120-939","offer_id":50216999223581,"sku":null,"price":19.55,"currency_code":"CAD","in_stock":true},{"title":"SWITCH,LIMIT,100\/130,AUTO \/ S1-02552068000","offer_id":50216999256349,"sku":null,"price":19.55,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/120-939","provider":"BCFurnace","version":"1.0","type":"link"}
