side by side does not freeze nor cool

Our refrigerator does not cool and the freezer does not freeze. The lights and fan are working. Air is moving inside, but not cold. Compressor doesn’t seem to be working. There are some occasional "clicks" heard, and the tank feels warm when refrigerator is pluged in. I cleaned all of the coils and made sure all vents are clear. Any idea what the problem might be?

usally the "clicks" are signs of a bad start relay on the compressor. The compressor make a vibration and low humming when running.
