Only place the cooler on a hard, flat surface. The cooler may make more noise if it is positioned at an angle. It’s also possible that the cooler may not have enough space around it to work properly. To ensure proper ventilation, allow 5 inches of space from the back and sides of the unit, and never cover the air circulation fan. Failing to do so may cause the cooler to overheat quickly and emit more noise than usual. Ensure that all components of the cooler are clean, as built-up dirt or other debris may cause the fan to overwork or overheat.  Do not use harsh chemicals or flammable substances to clean your cooler; use a dry or slightly damp cloth instead. Be sure to unplug your wine cooler before cleaning it. If your cooler is still making lots of noise, feel free to reach out to our Customer Service team for more information.
