We moved to the apartment last February. We didn’t immediately notice it, but the fridge has this issue where the wall would get all frozen. It’s probably some hole or something like that broken. So after a few weeks you can see ice/snow when you open the fridge.
Who is responsible for fixing this? Tenant or the landlord? Would I have any expenses for reporting it?
If I remember correctly, the old oven gum was replaced without any expenses on my side.
Which wall of the fridge? Ice dropplets on tha back wall are normal.
How cold did you set the fridge?
Generally it is the landlord. Call them to send someone. That’s the common procedure.
For repairs the landlord is normally responsible. But icing up can have several causes, the most common being the door not closing properly usually because one leaves it slightly ajar due to something protruding towards the door. It may be the seals are degraded in which case the landlord is responsible, damage to a wall is rare.
or simply it’s an old fridge without dehumidifier and you open it a lot
Aren’t the new fridges in the most rental apartments like that as well?
I got a Fridge that was built in 2012, so its reasonably new; ok 12 years old, but at the back of the fridge there is a little hole though which water drains. Some time ago said hole got blocked by ice and the fridge started to do just what your describing, turning into a freezer.
Take all the shelves out and check the back isn’t covered in ice. If it is than defrost your fridge. Assuming as an earlier poster has already mentioned there wasn’t an issue with it not closing properly.
Clean it. Dry it. Unblock the hole and make sure when items are in the fridge, that air still flows properly. I.e. Fridge isn’t jammed full or items too packed in.
And that the food does not touch the back wall.
We have a V-ZUG fridge. If something goes wrong we first contact the caretaker of the apartment and then the caretaker contacts V- ZUG if necessary and they send someone to check it out. That happened a year ago and they replaced the whole fridge. The problem with the wall icing up is the problem that we had. And the only solution was to replace the fridge. It was 18 years old.
We got a brand new kitchen before we moved in 7 years ago, and the problem with back wall freezing happened from the beginning, especially in summer. The fridges in Switzerland are very basic. We got used to No Frost fridges with active air circulation inside the fridge. Very noisy and power consuming, but no problem with freezing, neither in fridge, nor in freezer. When wee came to Switzerland 15 years ago we had to get used to the fridges that need defrosting from time to time. These fridges remind me of my childhood.
BS, most of the fridges don’t require defrosting. I can’t say about he freezer compartment as I’ve never used it
Never had to defrost a fridge either.
The freezer compartments which are just little thingies in the top section build snow and ice no matter what one does.
You never looked into yours? 
I got the impression it doesn’t make a difference whether they’re full or empty. But maybe if one never opens them and the seal is good they stay clear.
It may help if the door is opened as little as possible.
