A refrigerator door should close tightly and completely when you shut it. The seal of the refrigerator is essential when you want to keep the interior of the refrigerator cool and your food in good condition. If you find that the refrigerator door is not closing well or that it bounces open, this is a matter that needs to be attended to before your food starts to spoil.
Unplug the refrigerator.
Check for anything blocking the door. Remove any food that may be preventing the door from closing and close all of the drawers in the refrigerator completely.
Gently clean refrigerator door's gasket, which is the soft padding on the door's edge, by soaking a sponge in a mixture of dish soap and warm water.
Inspect the gasket for any twisting or damage. If the gasket is damaged, get the make and model of the refrigerator and order a new gasket. Remove the old gasket by removing the retaining screws with a screwdriver and then popping the new one into place. Then replace the retaining screws and see if the door is fixed.
Adjust the hang of the refrigerator door by loosening the screws on the hinges with a screwdriver, repositioning the door and tightening the hinges again.
Close the refrigerator door and plug it in again.
Close a dollar bill in the refrigerator door and pull it out again. If there is some resistance before the bill slides out, the door is sealing properly in that spot. If the dollar bill comes out easily, the seal is not working correctly.
