I’ll spare you the background as there’s ample horror stories of Samsung appliances (especially refrigerators). I would never have bought this one, but it came with the house. To its credit, it’s been working flawlessly the last 5 years, but I knew it was only a matter of time before its Samsung-iness reared its ugly head.
I’m not sure which control board is glitching out, but the symptoms are all in the front panel where the ice/water dispenser is. The fridge still cools, but the front panel is haunted on a good day (cycles through the settings by itself, but you can still use it if you fight it) and just doesn’t work at all on other days. So I guess the fridge still works as long as I don’t wanna do anything crazy like adjust the temperature, select between water and ice, or turn the ice maker on/off. Hurrah?
Ordered a replacement front panel board from ebay and hoping that’s the board that’s at fault. If it’s the “main” control board, I’m probably going to get rid of the fridge.
I’ve had it on a UPS for several months because of exactly that. My power’s pretty stable, but when it’s about to go out in a storm/winds, it goes full poltergeist for 2-3 seconds, flashes rapidly, and then either goes out completely or back to normal.
Granted, it raw-dogged power for its whole life until then, so it could have had accumulated damage.
