Using this Samsung French door closing bar is easy. First, make sure your fridge is unplugged to avoid any electrical hazards. Gently remove the old closing bar from between the two doors. Take your new bar and align it properly in the same position where the old one was. Press it firmly until it clicks into place. As for maintenance, regularly wipe the bar with a soft, damp cloth to keep it clean. Avoid using harsh chemicals as they may damage the bar. If you notice any signs of wear or if the bar doesn't close properly, contact us right away. Before purchasing, always double - check your fridge model to ensure a perfect fit.
