Product review (3 stars): I wish I had done more research before buying
update:
An appliance service repaired this problem and to possibly save someone the $100 - it turned out to be the switch just inside the fridge that senses when the door is closed.  The serviceman said the switch has electronics inside it.  He popped it out and replaced it.  I decided to open the switch and see for myself.  Lo and behold there are no electronics just plain vanilla single contacts.  One could easily clean or adjust the contacts or just buy a replacement sw.
None of that tells me why a switch that should last for a million cycles would fail so soon.  Lousy Quality control I assume.

Original Review:  This has been installed just a couple months over the 1 yr warranty period and is on the fritz already.  (!?)  I have owned other fridges years on end without any problems ever.  Maybe its just my time, statistically speaking.  The interior lights blink off then sometimes on when the door is open.  The motor is switching off with the lights which would possibly indicate a relay or thermal cutout.  PLUS, it seems like they could be (sometimes) on while closed, heating my food nicely.  In addition in researching the problem you see similar issues in the past including a recall.  LG was absolutely unconcerned about me or my fridge on a chat today.  Suggested I call the appliance repairman (when I asked about documentation or tech literature).
Too bad I went on a spree last year and bought LG washer dryer too.  Maybe this is the one-off.
