Check that the wine cooler is securely snugged in, and that it is set up properly. Ensure no components are damaged or malfunctioning in any way. Ensure that the cooler’s ventilation fan is not covered or blocked in any way, since this may prevent the cooler’s interior from reaching your selected temperature. Remember that the cooler’s actual internal temperature is dependent on the air temperature immediately around it. Although you can set the cooler’s temperature to cool to a certain temperature within its operating range, its internal temperature may not reach the selected temperature if the surrounding temperature is too high. In this case, try moving the cooler to a dry, dark space that’s cooler than its current location, and keep it away from direct sunlight. You can also attempt to unplug the cooler from its power source, then plugging it back in to see if that helps. If all of the above suggestions fail, please reach out to our Customer Service team for further assistance. Do not attempt to disassemble, modify, or repair the cooler on your own.
