Using this Hoover dryer door hinge cover is a breeze. First, make sure your dryer is unplugged to avoid any electrical hazards. Then, carefully remove the old hinge cover. You can do this by unscrewing the mounting screws. Once the old cover is off, take your new genuine hinge cover and align it with the mounting holes. The cover has a length of 125mm, and the distance between the mounting holes is 112mm, so it should fit perfectly. Simply screw it in place using the same screws you removed earlier. If you're unsure about anything during the installation process, contact us with your dryer's brand and model number, and we'll be happy to help. As for maintenance, keep the cover clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners as they could damage the cover. This part is fully guaranteed, so if you encounter any issues, don't hesitate to reach out to us.
