If the Cube is working but the pad doesn't seem to be cooling or heating properly it can be caused by a bad connection or a blockage. To resolve this issue try disconnecting the tubing from the Cube by using the release button on the bottom of the Cube. Check all of your O-rings and make sure that there are none that are damaged or missing. Then turn the unit on its side with the Cube connector turned upwards towards the ceiling and using your body weight push the pad connector into the Cube making sure that you have a straight on, solid connection.
