Ok, it's a refrigerator: plenty of room for my circumstances and he is aufällig inconspicuous. And mostly it is also quiet, which was not always so. At the beginning of the part has driven me insane! The thing was unbearably loud and always when the compressor has started, the part hummed as if I NEN Grizzly would have in the kitchen! All adjusting and aligning brought no improvement. I had to have even toyed with the idea to go back him again. Until I got the idea, sometimes back to check the grid. And lo and behold: The solution! After all I had tightened the 4 screws, he was quiet and did his ministry properly. No hum, no more rattling. Should not really happen at a new device but I press one eye and pull off a star.
