The Whirlpool WP2313637 Refrigerator Ice Cutter Grid is a replacement component used to cut formed ice slabs into uniform cubes within compatible refrigerator ice makers. Positioned inside the ice maker assembly, this grid contains a series of tensioned metal wires arranged in a precise pattern. During the harvest stage of the ice-making cycle, the system briefly warms the wires so they pass through the ice slab and separate it into individual cubes. The component connects within the ice maker frame and works with the heating and harvesting mechanism. By producing evenly sized cubes and supporting smooth ice release, this part assists in consistent ice production and stable operation of the refrigerator’s automatic ice-making system.
