I was referred to this site over the summer. I bought a used Haier kegerator off Craigslist.com. The Haier reviews were not that great but I figured i got enough accessories(3 taps, cleaning kit, 2 co2 tanks,) to make the purchase safe. Any way, go to
http://www.tommydehart.com/ for adjusting the Haier thermostat. He has step by step instructions with pictures. This worked for me, just be careful not to make it too cold or the kegerator will frost up and the beer line will freeze. good luck
