A:AnswerHello teacher9999 - Your refrigerator will automatically maintain the temperature level you select. The temperature control dial has 5 settings plus "0". 1 is the warmest. 5 is the coldest. At first, set the dial to 3 and allow 24 hours to pass before adjusting the temperature to your needs. - TREY@HAIER
A:AnswerHello Olley. It is normal for the top and sides of the unit to be warm or hot to the touch during normal operation. Make sure that you have an inch of air space around the case to allow good airflow. Thanks for checking. Olga
