I have a freezer that I plan to use to cool beer. Can I change out the thermostat to change my cooling range? Currently the freezer sets from -5 degrees F to +11 degrees F. Obviously this is too cold for beer which should be around 36 deg.F or so. Is controlling the temperature as easy as replacing the thermostat that will cut off the cooling motor much sooner? Does that typically mean that the thermostat resistance is decreased? I appreciate any input. Thank you.
