With freezer set at -7 and fridge at 33, the fridge stayed in the low to mid forties (danger zone for a fridge) most of the time. Only one time did fridge register 39 and this was after not opening door for over 24 hrs.  All temps verified by 3 thermometers (one of which is laboratory grade).  Downloaded and performed LGs 15 steps to fix poor cooling and it made no difference.  Ice maker spec is 2.5# per day, but my unit took a week to produce that.  Luckily I kept my 40 year old fridge which is now back in service and outperforming the LG in terms of cooling and ice production.  I am really disappointed to have to return this fridge.  I suspect that LG's inverter technology compressor is undersized, but I must admit it is the quietest fridge I have ever been around.
