A:Answer Hello srm777,
Thank you for reaching out and letting us know about your inquiry if the child lock locks the door when turned on. We understand that this may be essential for you. We're here to help.
As per checking, this Samsung refrigerator has a Control Lock feature. Its main functionality prevents accidental manipulation; you need to press and hold Control Lock for 3 seconds. It will disable all controls with the indicator (lock) on it. To deactivate, press and hold again for 3 seconds. Will enable the control buttons as usual.
For reference, you may refer to the link below for the user manual containing additional information about the Control Lock feature. See page 35.
