Using this Samsung fridge French door closing bar is easy. First, make sure your fridge is unplugged for safety. Then, locate the old bar between the two doors and carefully remove it. Take your new closing bar and align it in the same position as the old one. Secure it properly. Before plugging the fridge back in, double - check that the bar is firmly in place. As for maintenance, keep the bar clean by wiping it with a soft, damp cloth regularly. Avoid using harsh chemicals as they may damage the bar. If you notice any signs of wear or if the bar doesn't seem to be closing the doors properly, contact us right away. And remember, if you're ever in doubt about the part's compatibility, always check with us using your fridge's full model number.
