A:Answer Hi Rebe - Thanks for viewing GE! Current models do not have a "vacation mode". Our current refrigerators use an adaptive defrost which produces similar results. The refrigerator will only defrost as needed. It accounts for door openings and usage to determine when it is necessary to defrost and how long the defrost cycle needs to run. If the refrigerator is not being frequently used (ex. family on vacation), it will not defrost as often.
