Product review (1 stars): DO NOT BUY ANY LG REFRIGERATOR
I give this one star because I do not have the opportunity to give it zero.  Do not buy any LG refrigerator!  LG has the worst customer service and does not care about the quality and performance of their refrigerators.  My unit is 2 years old and the ice maker has black particles in the ice.  The internet tells me this could be teflon chipping off or perhaps mold growing in the unit somewhere (lovely).  Because of this, I am using ice trays like it's 1975.  When you attempt to contact LG about troubleshooting this issue the offshore call center agent begins going through a script of things to check or as I like to say, point the finger elsewhere:

1. Change your water filter they say.  Well guess what...my unit doesn't have a filter.  You'd think the product specialist answering the phone who you give your model number to would know that.
2. Use a water softener.  Sorry, I already have one of those.  Strike two.
3. Use a copper water line to supply the unit.  Again, I have one of those in place, so pointing the finger did not work.

The next step, I can pay over $300 to their out of warranty department to resolve my issue.  Or I can go to an authorized service provider and pay $78 for a service call to my home.  From there, the authorized service provider can call the LG technical support line to help troubleshoot.  Why can't I do that?  I'm mechanically inclined and I can work a phone.  Nope, can't further extort money from you if they do that.

I tried escalating the issue to a US based representative, who did not offer anything other than what the front line agent did.  In fact, the escalation person I spoke to didn't believe me that the unit did not have a filter, despite confirmation from their agent that my unit does not use a filter.

If you already own an LG appliance, I would contact them before the warranty expires to make sure every little bit is satisfied, because once that initial term passes, you may as well be stranded on an island.  If you are considering an LG appliance, I would look at another manufacturer, because LG does not stand by their products.
