I fixed the upper corner gap of our 32 after looking for a better quality retro fridge (couldn´t find any).
There was already a small cut in the seal. I enlargened it a bit, took some 25 cm of soft window seal and, without removing the tape that covers the glue, pushed it inside the gasket. I needed a long and dull screwdriver to do this smoothly.
I did this both horizontally in the top side of the gasket and vertically, downwards, maybe. This supposedly filled the gasket a bit and made it "thicker". Not enough though.
Hence I took some more of the window seal, lifted the top horizontal gasket a bit from under (carefully not to rip it off the door), and inserted the window seal under there. This makes the gasket even a bit thicker. I fit there quite snugly and I didn´t need to reveal the glue here neither. Still not enough.
Then I lifted the front side of the fridge about 3 milimetres. To do this I needed small, sturdy pieces of metal with plasti on the reverse aside to protect the wooden floor. I actually used round fridge magnets. Don't tell the kids... The small front screws meant for adjusting the angle of the fridge are to short and dropped off when I try to screw them more.
Together all this resulted in better sealing already. Then I spread vaseline on the gasket (only where the problems was). This helped some more. The vaseline was a bit yucky at first, but after wiping it off a few times it is at least not as visible (it sounds a bit funny when opened, though).
Now the seal works much better. It still has a small, say 5 mm long gap, but even that seals almost tightly when I give the door a gentle push after closing.
This fixed our problem. But I do wish Gorenje would make there SMEGs better in the future. This feels okay but only after settling with the fact that it really sucks more to invest 1400 euros again wihout any guarantees of mending.
