Where to buy parts for Danby dual zone wine cooler?

After reading through some of the issues here, and from what I have seen, I believe that the electronics on my wine cooler have gone out. It started getting warmer, and after about a week it is no longer cooling at all. I cleaned everything out and noticed the upper fan was not working. When I plug it into a different slot, it works fine. (this is why I think the circuit board has gone out).

What else should I check? When I plug it in, the compressor runs and the tank in back gets pretty hot, but the temperature inside actually goes up a bit, rather than down. Are there relays near the compressor that could have gone out, or is everything controlled off the main board?

Finally, where do I find parts online? I cannot seem to find any references to Danby parts anywhere, are there crossover brands that would work?

Thanks
