I fixed our garage refrigerator just a few weeks ago thanks to YouTube. The freezer side was cooling fine, but the refrigerator side was not cooling at all. When I opened the refrigerator door, I could feel cold air venting into the refrigerator from the freezer just fine, but it would never get cold and would eventually beep with a high temperature error. Meat had spoiled, drinks were hot, and my wife started looking online for a replacement. A little searching and digging led me to videos about replacing fans and motors and messing with the refrigerator hardware. That required pulling the refrigerator apart, which was well beyond my ambition. Finally, I stumbled on a video that described my problem exactly. It turns out that the air return vent had become blocked by ice, so when the refrigerator was closed air wasn't being pulled into the refrigerator side. When I opened the door, the open door caused air to move just fine. I took out a couple of shelves, found the return vent, chipped away at the ice blocking the return, and things have been working great ever since.
