I previously used a wine fridge for cigar storage while the cooling unit no longer worked it was a great way to store cigars as long as temps dont get too high. The problem with using a working fridge is moisture but not the addition of but the subtraction. Working fridges zap the moisture out of all its contents. If you want to test it put left over pizza in a ziplock and another piece open to the fridge wait a few days. Ziplock pizza still edible but open air pizza is cardboard with toppings. Now if you plan on using individual tupperdores then the refrigeration is not an issues. I have also heard of temp controllers people have used that can control when the fridge is able to turn on to cut how often the fridge runs. I used to run the wine fridge and several other humidors that was until I came into my cabinet humidor. My biggest issue with it is changing my batteries for my hygrometer and going to find certain cigars.... posted in another thread. I personally love have all my cigars in 1 place it gets easier not having to check on 4-5 humidor. Hope this helps
