The Whirlpool W10712394 Upper Rack Adjuster Kit-Metal for Dishwasher helps restore smooth and reliable upper rack movement. Designed to support the rack’s height adjustment, this kit allows the upper rack to be raised or lowered for better loading flexibility. It typically works by connecting the rack to its adjustment mechanism, helping it move evenly and stay properly positioned during use. Replacing worn or damaged adjuster components can improve rack stability and make loading and unloading dishes easier. The metal construction provides a practical replacement for damaged parts and helps maintain consistent rack operation. This kit is suitable for compatible Whirlpool dishwashers and can help restore normal upper rack functionality without replacing the entire rack assembly.
