I have a series 3 KK kegerator. It hadn't been used for a while, about 18m. I tried to use it last month and although it turns on it doesn't get cold. Suspect it needs gassing. I ended up buying a series 4. The electronics work fine, the compressor is running. Apart from not being cold, no damage. Comes with font and taps. Im in Melbourne, $100 pickup If its not gas related Ill give you your money back and you can have it for free. pm me if interested.
