Our 9 year old Samsung fridge is acting up. The freezer is set to zero but it's really around 10 degrees. Try setting it down to -10, doesn't help. Service tech says it's likely a sealed system issue (freon leak) or weak compressor, which is several hundred dollars to repair and it's hard to find someone that does such repairs. I replaced the temperature sensor, $18, myself. Didn't help. Looking at reviews online for new refrigerators. Quite a few horror stories. I imagine frustration escalates quickly as food spoils. We've been pleased with Samsung, however several recent reviews indicate issues and trouble getting qualified service. Similar comments about LG. Leaning towards Whirlpool, maybe GE or Kitchen Aid. Thinking side by side, standard size. Any suggestions, experiences are appreciated. Thanks in advance.
