Using your pre - owned Whirlpool freezer light cover is easy. Just place it in the freezer section where it originally came from in the fridge/freezer. Before installing, make sure the area is clean. As for maintenance, you can use a soft, damp cloth to wipe it down occasionally. Don't use abrasive cleaners as they might damage the cover. Remember, this part comes with a 3 - month warranty, but it doesn't cover normal wear - and - tear on the appearance or damage after you've installed and used it. If you notice any problems right after receiving the item, let the seller know right away. If you're not sure if it fits your model, ask the seller before making the purchase.
