Oasis Water Cooler Not Chilling

Here is how to adjust the thermostat on an Oasis water cooler. Locate the thermostat on the back and turn the screw 1/4 turn clockwise. Also check that the water cooler is plugged in and powered up. During a hot weather period, to start with the water cooler may not be able to keep up with the demand for cold water until people get used to being hotter than usual and reaching for cold water and drinking huge glasses full. I hope this helps, Bruce. info@wenlockspring.co.uk
