Is the evaporator/freezer fan (Item 7 in Section 10) running?
It is required to circulate the air in the freezer and the fresh food sections.

If it is not running, check the power to the fan. It should be 120 volts.
If you have power to it and it is not running it is toast and needs replacing.

Is the vent (Item 4 in Section 2) between the sections clear of food etc. in both compartments.
It must be for there to be proper air circulation.

If the above are OK.
Check that the compressor is running. You can usually hear it and it should be warm and you should be able to feel it vibrating.

If it is running all the time.
Check that it's fan is running.
Check that the condenser coils are clean
.
Remove the cover from inside the freezer so you can inspect the evaporator coils.
If they are heavily iced/frosted over to the point where the fan cannot pull air through them then you have a defrost problem.
If there is no frost or just frost in one area then you have a sealed system problem. Note that this test must be done after the compressor has run for a couple hours. If you do it shortly after a defrost cycle then there will be no frost and you will arrive at the wrong conclusion.

If the unit was tipped/tilted when moved did you leave it for at least 24 hours before plugging it in?
If not do that now.
