My wife bought me a refrigerator and a Johnson thermostat control for xmas. The fridge portion is already maxed out, and the freezer is completely unused. I wish there was some way to adjust the temp in the freezer space so that I could utilize that as well. Has anyone every been able to use the freezer space in a similar setup? Or could I just use it as an additional freezer? I just have no idea how the temp will maintain in the freezer area when I have the fridge set to 55. Any thoughts?
