LG refrigerator occasional buzzing sound
I have an approximate 16 year-old LG refrigerator that has been buzzing for a few hours at a time usually in the evening when I catch it. it happens maybe every few weeks. it’s still cooling. it happened about three times and I have a video of it. it buzzes in the bottom back of the refrigerator. It could be the fan or the compressor, but before I call a repair person, I wanted to see what people think and also whether this is something that they would have the part for given the age of my refrigerator. I don’t wanna waste a repair person‘s time and my money to find out that it can’t be repaired or that they can’t determine the problem because it’s not actively buzzing when they come out. I may just have to wait until it finally fails someday. LGc25776ST.
