Barbra, Dale is probably correct and you'll most likely not be able to d much your self except call service, but: Two guesses, first, obviously there may be a freon leak..If the compressor turns on but doesn't seem to change speed or sound after it runs for a while, I think it isn't able to build up pressure/vaccuum in the system, thus a possible leak.
Second, if it's like many frost free systems, there should be a fan that blows the cold air across the heat exchanger where it's cooled, then around the inside. if you turn it on, open the door, and check for any moving air. It's possible the fan is dead or clogged and thus not moving the cold air around, and that keeps the whole system from working. Does the compressor turn off after the mentioned few minutes or keep running? Are there coils or fins on the back or bottom that you can get at? if so, do they get warm after it's run for a while? If not, then again, it's not pressurizing properly, most likely the leak again. Tom Net-Tamer V 1.13 Beta - Registered
