The Whirlpool W11489994 Refrigerator Rail is an essential component that makes certain the smooth operation of your refrigerator's drawers and shelves. Consider it a track system which functions such as a slide. These rails are positioned within the refrigerator to support and guide specific drawers or shelves. As you pull out these compartments to reach your food, the rollers beneath them move smoothly down the tracks. This allows for smooth and frictionless movement. A broken or damaged rail might severely limit this usefulness. Drawers can snag, wobble, or become misaligned, creating frustration and sometimes damage the components themselves. Replacing a damaged rail with the Whirlpool W1148994 guarantees that these drawers and shelves move smoothly again.
