Spray a good quantity of WD-40 on the spindle of the fan motor where it enters the motor itself. This should get the fan working smoothly with no noise. This will probably solve the other problems, as the fan prevents various components from overheating and shutting down.

Defrost the unit for two days with the doors open...I know you're going to lose your contents. You may have ice on the coils internally. Next make sure you've cleaned the external coils under the unit. Leaving liquids open inside the unit or setting it colder than required will both cause issues like the ones you've got. Also, be sure all air vents inside the unit are unblocked and the door closes tightly all around.
