Temperature is too Warm/Refrigerator is not Cooling Properly - Undercounter Refrigerator
Possible Solutions
Is the door opened often?
Be aware that the refrigerator will warm up when this occurs. To keep the refrigerator cool, try to get everything you need out of the refrigerator at once, keep food organized so it is easy to find, and close the door as soon as the food is removed.
Is the base grill blocked?
For best performance, do not install the refrigerator behind a cabinet door or block the base grille. Blocking the base grill will prevent proper airflow and could cause the refrigerator not to cool properly.
