Ned....the compressor cools down air, which is then blown into the fridge by a fan. Maybe not all fridges use this principle, but for instance the display fridge I use for cold drinks in the restaurant does.

Actually.. the compressor compresses the closed circuit coolant gas to higher pressure, which heats it up. Then this extra heat is released to the room via heatsink.

After that the gas goes through a small pinhole and coolant gas pressure drops, which means that the temperature drops as well. This cools down the evaporator coils inside the fridge. A fan inside the fridge is used to speed up the heat conduction process.
