The biggest consistent problem mine has is the display panel burns out LEDs in a matter of weeks. Yes, burning out LEDs. If I put in a new panel (which thankfully is fairly easy, just a ribbon cable and a couple screws) it works for a few weeks, then the LEDs start to burn out again. So it becomes a guessing game of whether you're going to get water, crushed ice, or cubed ice.

There is basically no warranty on replacement parts. We stopped replacing that panel, and now we just play the guessing game. Fortunately the fridge does remain functional as a cold box, at least. There are a few other problems, like accumulating ice in the tray at the bottom, but this is not really a Samsung-specific problem, lots of fridges develop this issue.

I have a samsung fridge and it makes loud cracking noises, sometimes it even wakes me up at night. They told me the noises were normal, funny thing that fridge is advertised as being really quiet

I have a samsung fridge, the ice maker does not work. I've tried a lot of things to get it to work, none of which worked. This is not an isolated issue, if you read online it's just accepted that the ice maker will at some point cease the function and will never work again.

Search "Samsung fridge" on HN to find a bunch of comments on what they've done wrong. It seems they're very eager to overengineer and add technology either just because they can, or possibly to aggressively pursue environmental regulations on energy usage and such (so they can claim to be at the top of efficiency rankings.)

I got rid of a Samsung fridge freezer recently because the front door rusts. The integrated water/ice dispenser sits atop a piece of door metal folded over, and the edge must not be protected as any spills not IMMEDIATELY cleaned up caused creeping rust.
