A refrigerator upgrading system is provided to carry out upgrade of stored programs simply by using a communication socket instead of disassembling corresponding electric parts. A refrigerator upgrading system includes a communication socket(32) mounted in a refrigerator and able to be exposed to the outside to be connected to an external terminal, and a first microcomputer(15) having a communication module(15a) connected to the communication socket with a predetermined connection line, so that the first microcomputer carries out the upgrade of stored files through the communication with the external terminal. |
