I am assuming that when you checked the compressor you also checked the condenser coils and the vents for cleanliness.
Also that the condenser/compressor fan runs OK and it’s blades are clean.
Is the compressor cycling or is it on all the time?
If it is cycling then odds are that it is a thermostat problem.
If on all the time, remove the cover in the freezer so you can inspect the evaporator coils.
If they are heavily frosted/iced over you have a defrost problem.
If there is no frost or just frost in one area (Usually where the freon enters the coils) then it is a sealed system problem. This will be an expensive repair as you will need a pro. Often it makes more sense to put the dollars towards a new unit.
