Using this Samsung French door closing bar is straightforward. Just place it between the two fridge doors where it originally belongs. When installing, make sure it's properly aligned for a smooth closing function. As for maintenance, keep it clean by wiping it with a soft, damp cloth regularly. This will prevent dirt and debris from building up. If you notice any signs of wear or if the bar doesn't seem to be working well, check if it's loose or damaged. If you're unsure about anything related to this part, don't hesitate to contact us with your fridge's model number. Also, remember to double - check the compatibility before making a purchase to avoid any issues.
