How to use the Child lock on Samsung Refrigerator?

Child lock on Samsung refrigerators prevents accidental changes from taking place on the control panel, keeping your food and your family safe. If child lock is enabled you will be unable to use the control panel and some features such as the ice dispenser may not function.

Child Lock (Control Lock): Some refrigerators have a child lock (control lock) that locks the control panel and the dispenser at the same time. This appears on panels that are located outside of the refrigerator and can be locked or unlocked by holding Ice Maker Off until you hear a chime (3 seconds).
