Sound is very subjective. What may be annoying to some people can be considered perfectly normal by others. You also tend to notice new sounds much more at first until you’ve grown used to them. It is a good idea to know which sounds are normal so you don’t worry unnecessarily that something might be wrong. A
wine cabinet will make two main sounds. The compressor comes on at regular intervals and usually makes a low humming sound. The evaporator also makes a noise, rather like a submarine. This can vary in volume.
Built-in wine coolers also emit two types of sound. These are usually the compressor and the fan, making sure the wine cooler is properly vented. The fan starts up quite frequently to maintain a healthy, odourless environment for the wines.
