I have LG Bottom Freezer Refrigerator for 5 years. I noticed that yesterday that a funny motor sound came from the back of the refrigerator. When I open the refrigerator or freezer door, the sound would stop, but whenever I open either door, the sound would resume. I even vacuumed the bottom of the refrigerator in case the dust is causing the problem, but the same sound persists. What is wrong with my refrigerator? What can I do to fix it? Thanks for any help or information!

Hi,
The problem could be a bad bearing in the condenser or evaporator fans...more likely though is that the evaporator fan is hitting an ice build up on the coils...this can be caused by a bad defrost timer...
more closely check on the sound... you will find it....

a few drops of oil on the fan shafts just ahead of the motor will not hurt either...
