Roaring sound My LG french-door refrigerator model LFX25960 ST has suddenly started making a roaring sound. The refrigerator is barely a year old and has already had the ice-maker replaced. The sound stops when either of the refrigerator section doors are opened. The sound gets louder when the bottom freezer door is opened. The sound seems to be getting louder as time passes.

I have had the same issues. I have owned my LFX25960 for 18 months. All the cooling, noise, and condensation problems are related to 2 fans. One for the freezer/refrigerator compartments and One for the Ice Maker. The fans, apparently, are not sufficient to move enough air through the coils located behind a plastic panel in the freezer compartment. The part numbers for my fans are 1. Ice Maker 4681JB1029E and Refrig/Freezer 4681JK1004E. It is not impossible, but fairly difficult to replace them yourself. You have to remove the large slide out freezer drawer and glides. Then work the back freezer panel loose from the bottom. Be careful not to break it. It is plastic.
Routine maintenance: Pull the refrig out from the wall and blow-out the coils and fan located on the lower right rear. You might find it easier to do this by removing the cover on the lower, back of the refrig.
