I keep my beer in small chest freezer (keezer) at 2 degrees. But you can have it higher, it just carbonate easier at lower temps. My brewing fridge can keep temp around 4 degrees without any stat. So you should be OK. But just test it, play with fridge own thermostat. You can keep beer at higher temps, like cellar temp, but carbonation will take longer.
