So just got my fridge that I will be converting to a kegerator soon and I have the temp controller turned almost to the off position and my thermometer is reading about 36F. I'm worried about the temp dropping too low and freezing my lines and also about not being able to o much warmer to serve certain styles at temp. I know I can always let the beer sit for a few min. To warm in the glass, but it's not ideal. Any suggestions on how to fix this?
