Using this AEG mica waveguide cover is easy. First, make sure your microwave oven is unplugged to avoid any electrical hazards. Open the oven door and locate the old waveguide cover. Remove the old one carefully by following the manufacturer's instructions. Then, place the new mica waveguide cover in the same position as the old one. Ensure it fits snugly and securely. When using your microwave, keep in mind that the mica waveguide cover helps to protect the oven's internal components from food splatters. Avoid using sharp objects to clean the cover as it may damage the material. To maintain the cover, wipe it gently with a soft, damp cloth after each use. If there are stubborn stains, you can use a mild detergent. Replace the cover if you notice any signs of damage, such as cracks or holes, to ensure the proper functioning of your microwave oven.
