Do upright freezers have a thermal shut off switch if the compressor runs too long or gets to hot?
There is probably a safety device of some description incorporated into the design though it probably isn't to blame for the trouble.
You need to discover whether it is the fan, compressor or both; neither should run constantly. The condenser fan is only needed while the compressor is pushing the refrigerant around the circuit and in many designs, where a belt driven compressor is used it is usual for the fan to be mounted on the extended motor shaft so they can't run independently.
If the compressor runs constantly and the cabinet doesn't suffer from excessive freezing it is almost certain either the compressor is failing or there is a leak and refrigerant is being lost - probably the latter.

29313 Freezer needs a gasket replaced and possibly a thermostat...never shuts off..
Try sealing the door with tape to see if the thermostat will work to turn it off.
My Kenmore upright freezer had a separate cross seal down quite low, on the freezer not the door. I reversed the door seal so the damaged top part was below the cross seal and voila, no more leak.
If it needs a thermostat I suggest getting it sealed first. Mine was only 10 or so years old but Sears Parts said seal no longer available. Good luck
