I had the same exact problem with the addition of a lot of ice forming on the botttom of the freezer. It turned out to be a clogged defrost drain behind a panel in the freezer. There is a collection pan under the evaporator coil (a snake like tube with siver tinsle wrapped around it it). Blow some compressed air through it or use a snake to make sure it is clear.
You may find a lot of ice behind that panel in wich case you will have to defrost it completely for safe efficient operation.
