Using this door latch assembly is easy. First, make sure your dryer is unplugged to avoid any electrical hazards. Then, remove the old door latch from your Bosch WT or WTY series dryer. Simply attach the new latch in the same place as the old one. When you're done, plug your dryer back in and test the door to make sure it latches properly. As for maintenance, it's a good idea to check the latch regularly for any signs of wear or damage. If you notice anything wrong, replace it as soon as possible. Remember, if you're not sure whether this latch is right for your dryer model, contact us with your full model number before you buy.
