Hi have brought a second hand fridge which seems to get to cold, checked it this morning and the temp gauge i put in was at -2.2, i was wondering if I installed a inkbird and put a heater in it would this cure the issue of it getting to cold, as i could then use it as a brewing fridge rather than a normal one, and when nothing is fermenting just set it at 4 degrees and keep my bottles cold, or is this a silly idea.
