Premium design for the modern kitchen The RS51K5680SL, it’s what you don’t see that helps bring refined beauty into your home. Recessed handles and hidden hinges provide a touch of elegant minimalism that complements any modern decor. There’s still plenty for the eye to admire, from the sophisticated pattern design to the blue LED display. Twin Cooling System™ gives you the best of both worlds The RS51K5680SL uses two separate air flows and precise temperature control to maintain optimal humidity levels on both the refrigerator and freezer sides. This Twin Cooling System™ helps keep your apples fresh, prevents your ice cream from getting freezer burn, and stops ice cubes from smelling like the garlic bread you’ve stored in the refrigerator.
