Hello Kisha! We are sorry to hear that your unit is not cooling. I have provided a few solutions to help rectify the concern.
Check if the power plug is properly connected.
• Check if the set temperature on the digital display is warmer than the freezer or fridge
inner temperature. If it is, set the refrigerator colder.
• Is the refrigerator in direct sunlight or located near a heat source?
• Is the back of the refrigerator too close to the wall, preventing proper ventilation?
I have also provided a link to help as well.
