This a GE refrigerator/freezer that is not getting cold enough and is not freezing the food in the freezer section.  As you can see in the video, the lower part of the evaporator has a frost pattern on it.  This frost layer can tell you if the compressor and sealed-system is operating properly.  The thin  frost layer should evenly coat the entire evaporator and not just the lower part.  Under normal operation, all the coils should be absorbing heat from the freezer.  The bi-product of this absorption is frozen condensation on the coils.
