I have a frigidaire freezerless refrigerator that is blowing warm air. The unit is running, the fan is blowing, the compressor is hot to the touch. The hot line coming from the compressor is hot and the cold line is semi cold. I took the panel off on the inside and there was little ice on the coils mostly there was build up by the thermostat. Any ideas?

I took the relay and run capacitor off of another unit we had and swapped it because I thought that might be the case. It still ran the same so I came to the same conclusion, either a leak in the coolant system or a bad compressor.
