I had an issue where my compressor suddenly failed.  I called LG and went through several easy steps to diagnose it and for the customer service rep agree with me that it is the compressor.  This was a very quick process and a technician was scheduled about 4 days later.  The technician Wahid Aleko came to my house and was very professional and interactive with my son who had some interest in what was happening.  Wahid was fantastic and I am very appreciative for his time.  We have had no problems since!  Thank you Wahid and LG customer service!
