My Kenmore refrigerator is making a buzzing sound. It’s intermittent and getting louder as the days go on. It goes off when I open the lower freezer drawer. It then goes back on when the drawer is closed. I also removed a large chunk of frost around the cold air duct in back of the freezer a week ago. The frost is forming again.
I’m pretty handy with things and could probably fix it if I knew the problem and probable part that is defective. I wonder if the compressor fan is goofed up. Any thoughts?
