When you open a fridge or a freezer and then close it again, why does it become harder to open again right after?

When you close the door quickly, it compresses against the seal, pushing out a little more air than the fridge usually contains. This causes less air pressure in the fridge for a moment, and the air is slightly cooled, which adds a little pressure difference. After a minute or so, enough air leaks in that the pressure equalizes.
I haven’t seen the real answer so I will tell you:
As other posters have right, when the door is closed again, the air contracts, creating a suction cup affect.
When you first initially open the door, there is less suction because the air inside the refrigerator is mixed with the already cold air in all the cubicals and storages so the effect is less.

There is often a hole at the back of the fridge through the fridge wall that should equalize the pressure inside the fridge. Sometimes this hole becomes clogged and then the fridge becomes more difficult to open. by clearing this hole it will be much easier to open.

I’m terrible with physics, but I think it has something to do with reactivating the suction of the rubber seals from the closing motion. I have no idea how to describe it scientifically though 😛
Vacuum. Temperature and pressure are related. You open it and let a lot of warm air in, and now you close it and that air starts to cool.
Due to their relation, a drop in temperature means a drop in pressure – now the door is actively being sucked close due to pressure differentials.
