The compressor is running and the condenser fan motor is running and freezer fan motor is running and its not getting cold at all, that indicates a sealed system problem.
The sealed system consists of the compressor, condenser, evaporator, heat exchanger, filter/drier and refrigerant.
Common problems with a sealed system are bad compressors, refrigerant leaks, and system restrictions. Sealed system repair costs will often exceed the machines value.
We don't get into sealed system repair here, there's a lot to it. Compressor/sealed system work is not a repair a normal consumer can do. Doing compressor/sealed system work is very unique craft that you need to be trained in with lots of hands on experience.
Doing sealed system work requires you to have a turbo torch, acetylene for the torch, knowledge of how to use and weld with a turbo torch, also having a vacuum pump, and the proper amount of R-134a to use, changing the Filter Drier as well, solder, flux, silfloss, sandpaper, etc.
You need to be a certified Type 1 40 CFR part 82, subpart F. AHAM-NARDA Refrigerant Tech. to change Compressors or do any sealed system work involving Freon(Refrigerant Gas). I got certified on 11-17-1994 when i worked for Montgomery Ward Service Dept.
You'd need to have a licensed refrigeration tech come out and do it for you, IF you decide to have it fixed vs buying a new refrigerator.
