Can you feel the compressor vibrating?
If yes then is the freezer fan running?
Check the frost/ice pattern on the evaporator/freezer coils.
If no you may want to unplug the unit, let the compressor cool down and then give it a try. If it does start up then check that the vents etc. for the machine compartment are clean.
Also if the compressor is not vibrating but is hot then I would check the compressor’s windings etc…
