The refrigerator’s overall weight is dependent on a number of components and parts. The biggest factor that directly impacts the weight is their size. Full-sized refrigerators measure up to 70 inches (almost 6 feet) tall. Similarly, some of them come with insulated walls, and these walls are super thick and include heavy insulation often made up of rigid polyurethane foam.Then a refrigerator has various mechanical components such as refrigerant, compressor, coils, door, drawer, etc., and all these are significant contributors. Hence most refrigerators are heavy.
