Product review (1 stars): Design flaw results in fan noise
After a couple months of purchase the frig started making a loud vibrating sound when the fan runs.  Called out a tech who opened the freezer drawer and borrowed my hair dryer to blow it against the back wall.  He said this has to be done from time to time, it's a design flaw where ice builds up behind the wall and the fan begins to brush up against it.  Would never buy an LG appliance again, as now I have to do this every couple of months myself.
