I have a Electrolux icon built in fridge that will run for a day or so and the the freezer will stop cooling and then after a while the fridge will stop cooling. It has Samsung guts but they don't support it. I had a repair guy out and everyone said it was the main board, swapped it and that didn't fix it. They ordered a second board just to verify it wasn't the board. Still no dice. My repair guy threw in the towel and gave up. If I turn it off then back on it will run and cool. The fans try and kick on but don't.
