This Whirlpool WRT771RWYB refrigerator comes with a Temperature Management System enabled by 6th Sense Technology. This allows it to adapt and deliver great cooling performance and food preservation. The adapative defrost in the freezer saves up to 12% more energy by running the defrost cycle only when necessary and monitoring how often the compressor operates and the doors are open. The FreshFlow Air Filter reduces common odors and is fifteen times more powerful than baking soda. The contemporary design brings a modern look to any kitchen with top freezer refrigerators that features smooth, contoured doors, hidden hinges and a flush base grille.
