Straighten the door by adjusting a hinge
A sagging refrigerator or freezer door doesn't just look bad. It can cause the door gaskets to seal poorly, and that means your fridge will work harder to keep the milk cold. It can also lead to frost buildup in the freezer. To realign the door, just pry off the hinge cap and loosen the hinge screws. Then align the door with the top of the refrigerator. Adjust only the top hinge to straighten an upper door. To realign the lower door, adjust the middle hinge. Moving the middle hinge will affect the upper door, so you may have to adjust the top hinge afterward.
