I understand your concern and I'll be happy to help you, I would suggest disconnecting the unit for 5 minutes, and then connect it back and set the unit in the recommended temperature, which is -2F freezer/38F fridge, if after this the unit still isn't holding the temperature please feel free to contact us via our live chat: https://bit.ly/2qLSIlI Facebook or Twitter: @Samsungsupport, or you may call us at the 1-800-SAMSUNG. We appreciate your business with us.
