So many possibilities:
If it's frost free check the evaporator. If it is iced up it can be a bad defrost heater, bad defrost timer, bad door gasket (if you live in a humid environment). The compressor will run until it overheats and never gets the air inside cold. When you try to restart it, if it hasn't been off for 5 minutes or so in order to let the line pressure drop, the pressure in the system is too high for the compressor to start against. It will hum a second and the thermal overload will then kick the motor off.
It can also be a bad start relay. The motors on those old ones was basically two sets of windings in one motor. The relay is supposed to energize both windings until the current drops (the motor starts turning) then drop one set out. If the relay is not switching the start windings on, the run windings will hum for a second but not be powerful enough to get the motor turning. The thermal overload will then kick the whole motor off .
Anything else = get a new fridge.
