Reading these forums seems to reveal that the Sanyo 4912 is the most popular mini fridge to convert to a kegerator. Luckily I found a used 4910M on craigslist for $100. This was my first time using craigslist, and the picture of the fridge looked good. I was told the fridge was "clean" but I quickly found out that some people's definition of clean is very loose. The fridge did not smell, but everything was sticky, like a soda exploded in it or something. I was a little mad at myself because I still paid $100 for it but after I got home I found out it is actually a 4912 not a 4910, so I guess its a little newer than I thought. Also it cleaned up very well with hot water and a little bleach.
I had to lay it on its side to transport it, which made me a little worried about oil seeping into the coils. After letting it sit over night I let it run, and it works well. I can get it to about 35 deg F on setting 5, and I think it might get to freezing if I turn it up a little more. However when I put my hand on the compressor after a few minutes of being on it feels very hot. I cant keep my hand on it for more than about 5 seconds. If anyone else has this fridge, is this normal? Does your compressor get this hot? I pointed a fan at the compressor and this does keep it cool even when running.
