The door of the freezer is jammed because the first time we open it, the cold air goes down. Standing barefoot in front of an open freezer, you will surely notice that the toes have become cold - cold, dense air sweeps over them. It makes room at the top of the freezer for warmer room air.
When we close the freezer, a new portion of air is cooled and compressed, creating a partial vacuum, from which the door closes tightly as if the ground in since the outside air pressure is higher than the inside.
If the day is exceptionally warm, the temperature difference inside the freezer and in the room where it is located will be even more noticeable. In this case, you have to push the sealing gasket on the door with your fingers to let in some air in the freezer and equalize the pressure - after that, the door will be easier to open.
The partial vacuum created inside the freezer quickly disappears as the gasket on the door is not tight, and the pressure is gradually leveled due to air leaks.
If you have not noticed that the door is difficult to open, it's time to check the sealing gasket. Perhaps it gives a lot of cold air leakage. As a result, the freezer has to work with overload, which is harmful to the environment and your wallet.
