Using the Westinghouse Side by Side Fridge Compartment Light Cover is easy. First, make sure your fridge is unplugged to avoid any electrical hazards. Then, carefully remove the old light cover. You can do this by gently prying it off. Next, place the new light cover in the same position as the old one and press it firmly until it clicks into place. Once it's on, plug your fridge back in, and you're good to go. As for maintenance, it's a good idea to clean the light cover every few months. You can use a soft, damp cloth to wipe it down. Avoid using harsh chemicals as they might damage the cover. Also, be careful when handling the cover to prevent cracks or breakage. If you notice any issues with the light cover, such as it not staying in place or if the light isn't shining properly, don't hesitate to reach out to us for further assistance.
