I think you understood the reason perfectly. If I were you, I wouldn't fiddle with it, but fix the cause once and for all (which is what we did with our problematic bedroom corner after fiddling with it – other than the fact that it cost money – had no effect). From my perspective, it would be to insulate the exterior walls in the affected corner with climate control panels. They come in 3 cm or 5 cm thicknesses. Depending on the temperature of the wall, it should be a thin or thick climate panel. However, a thin one (3 cm) is usually sufficient. Install the climate control panels on both exterior walls and replace the built-in refrigerator with a floor standing refrigerator.
