I am experiencing similar problems with my LG Refrigerator. I did not but it, but it came with the house we bought in Nov 07. It can't be more than 2 years old, if that, and now the Fridge part is not functioning. First the ice maker quit about a month ago, then a fan motor noise for the last 2 weeks, and not its dead. The freezer still works, but not the fridge. I'm sure I'm facing some kind of rediculous charge to fix it... prob better off dumping and getting a different unit all together from a solid brand name.
They don't make things like they used to...
