I have a Haier HBF05EBSS "Beverage Dispenser" it's worked great for 3 years. I came home after Thanksgiving travel and found the kegerator was not cold at all. The compressor was hot but clearly no cooling had gone on for awhile. I unplugged it then plugged it back in. I heard the characteristic click of the overload protector kicking in. At this point I figured I had a serious issue but started investigating the electrical components. I did some troubleshooting for compressor issues and didn't really find anything out of the norm. After I reassembled everything I plugged it back in. To my surprise it started up fine and it was cooling. I then unplugged it rolled it back to it's normal location and plugged it back in. Nothing... The overload didn't kick in but I could hear a faint humming from the compressor. So I unplugged it again waited a little while then plugged it back in started up again. I replaced the starter relay with the exact same model relay. Same story. Starts once then doesn't seem to want to start again for awhile. What could be going on? Is there anything else I should check?
