Refrigerator doors are the hinged panels that provide access to the interior of a refrigerator. They are designed to keep cold air inside while preventing warm air from entering, which helps preserve food and beverages. Most refrigerator doors have shelves and compartments for organizing items like bottles, jars, and dairy products. Many refrigerator doors come with features such as ice makers and water dispensers for added convenience. Some models also have a french door design, which includes two side-by-side doors that open to a wide space, making it easier to store larger items.
