What should I do if the refrigerator is not cooling properly?

First, check that the power cord is properly plugged in and the temperature is set correctly. Make sure the refrigerator is not located near a heat source or in direct sunlight, and that there is at least 5 cm of clearance from the rear and sides. Also ensure food is not blocking the ventilation vents, as obstructed airflow can prevent proper cooling. (Page 43)
