You guys with a lot of boxes need to look into a Fridgadore, a little more work but well worth it, needs a Digital controller($35 on ebay) and depending on where you live a Humidifier or Dehumidifier, i have both as my areas humidity swings from 20 to 90 throughout the year. still need to use Tups in it for loose cigars, (when the ref kicks in it sucks all the humidity out hence the Tups, Humidifier takes a few mins to get it back up)
Controller turns power to ref on when temp gets to 60 and off when it hits 68 (fully controllable temps) then turns on the Humidifier at 61 and off at 66 also controllable.
