It is important that a refrigerator be set to a level position. The door swing, drainage and proper operation rely on a level appliance. Because floors are often not perfectly level, it may be necessary to adjust the leveling feet on a refrigerator to bring it into a level position.
Place a level on top of the refrigerator near the front. Do not put it on the door because the door may not be aligned with the refrigerator case. Check that the refrigerator is level. Also check that it is level from front to back.
Before leveling, unplug the appliance to avoid an electrical shock hazard. Never tip a refrigerator or freezer, it is very heavy and can fall causing damage or injury. Always have an able bodied assistant when moving heavy appliances.
If it is not level, adjust one or more of the feet until it is level. The feet are bolts that can be turned to raise or lower the refrigerator. If they cannot be adjusted with your fingers, use a crescent wrench or pliers.
If you have an ice-maker, it should also be checked for level after first leveling the refrigerator. It can be repositioned by loosening the mounting screws, adjusting it for level and then retightening the screws.
