I just installed a fancy new 7 cu. ft. freezer to use as a full time fermentation fridge. It's got 6 gallons of lager in it fermenting at 51F. The freezer seems to cut on every 45 minutes or so, but only for 3 minutes. I've got the tolerance set at 1C, should I raise it to get a longer duty cycle, or is it ok for the compressor to run for such a short amount of time?
