An electrician can quickly find out how old a GE refrigerator is. The year a GE refrigerator was manufactured is coded into the serial number of the appliance. The serial number should be differentiated from the model number.
The serial number begins with two or three letters. The first letter indicates the month in which the appliance was manufactured, and the second letter or second and third letter indicate the year. Some letters represent a series of years in 12-year increments, so an owner who knows the approximate period of manufacture may be able to determine the refrigerator's exact age without professional help.
