I've been an appliance technician for 41 years and I don't recall ever seeing so many bad compressors (big box store dehumidifiers excluded) as LG refrigerators have. Two weeks ago, the we scrapped out 8 LG refrigerators, all with bad compressors and not one of them was 4 years old. One month ago we had a customer who spent several days endlessly calling LG again and again and LG finally agreed to replaced their compressor on their 2 year old refrig.
This past October I was doing a washer repair and the customer mentioned that their very young LG refrigerator was going to have the compressor replaced in warranty but that the service appointment was nearly one month out. They inquired if my shop could do the repair faster. I knew we could do it in just a few days but fibbed (because it was an LG) and said no, we're backlogged also. In March, just before the COVID-19 quarantine began, I was back at the same customer's house to repair their drawer microwave oven. They told me their LG refrig just went out again and wondered if the warranty serviceman had done a bad job. I looked over the paperwork and discovered that I knew the tech (and he's excellent) who replaced the compressor. So through no fault of their own, the warranty service company got a bad yelp review from that customer. Sure am glad I fibbed and didn't do the job or that would've been me.
I don't know if new replacement LG compressors are any better but currently we suggest when refrig shopping, pick anything but LG.
