If you have a thermostat knob, you can adjust the temperature by rotating it clockwise or counter-clockwise to increase or decrease the temperature. If you don't have a thermostat knob, you can try adjusting the power setting up or down depending on the lowest and highest settings available. You can also unplug the refrigerator for a couple of minutes and then plug it back in to reset it.
