In general, your Smart Box shouldn’t make noises greater than what would be expected from any refrigerator or freezer unit.
For instance, refrigerant circulating throughout the system may produce an airflow sound, or the compressor may generate a buzzing sound, especially when starting up or shutting down. These sounds would be considered a part of normal operation.
If the sounds or vibrations your box is experiencing seem more significant than what is described above, ensure that your Smart Box’s cabinet is not touching a wall and that proper air circulation is possible.
If your unit continues to experience significant noise or vibrations, please contact support.
