I have a Danby Kegerator DKC052BSLDB. It was bough new about 6-7 years ago. It is no longer getting cold. I searched online and decided to replace the relay, capacitor and overload with a three in one device. When I turned it on it seemed to have done the trick as I could hear what I think is the compressor turning on and a gurgle sound like water being moved around in the cooler area, yet it is still not getting cold. Nothing has happened, It wasn't moved. I don't think its the temperature control because I can turn the knob and it will turn on and off. Any ideas?
