Ice build up is caused by several things:
1. Improperly adjusted low pressure cut out control found on the older refrigerators
2. A slight under charge of refrigerant.
3. A dirty evaporator coil (check both sides of the coil).
4. In the case of the freezer side, icing is caused by a defective electrical defrost element or time clock with the defrost not set properly.
There is no water dispenser on those units. There IS however a condensate drain line, a tube from which should be fit to drain the water to a heated pan near the bottom of the refrigerator where it can evaporate.
None of this is something that a layman can repair. If you can tell me which direction you are from the center of the nearest town or city I will most likely be able to locate a specialist in these older model units for you.
