Using these Chef oven door inner glass seals is easy. First, remove the old seals from the oven door window. Then, carefully place the new seals around the inside of the window, making sure the 16mm cutouts line up with the corners. Press the seals firmly to ensure a good fit. When using your oven, avoid using sharp objects near the seals to prevent damage. To keep the seals in good condition, clean them regularly with a mild soap and water solution. If you notice any signs of wear or damage, replace the seals promptly. If you have any questions during the process, feel free to contact us.
