I bought a frige and bent the freezer down and there is plent of space to fit my keg and CO2 tank. Problem is that when I leave it running, even on the minimum level, the temperature gets way too cold. We are talking 20F cold. There was a coated wire that I assumed to be a thermocouple of some sort and bent it along with the freezerplate. That didn't help any though. Is there some way to remedy this? Thanks in advance.
