Ответ на "Cooling problem with refrigerator"so I know this post is old, but I had this problem and did not see my solution so here it is. My samsung refrigerator module number rf20hfenbww top part (the actual refrigerator not the bottom freezer) was not getting cold. After a few days with it unplug I begin to tear it down and found out the the fan behind the inside cover was not running. I had to remove the three screws holding it to the back of the inside wall (be mindful that one of the screws is behind a little tab in the middle of the plate). To my surprise the red wire going to the fan was burned apart, so after rewiring it back together and put everything back together it started cooling again.
