Problem with mini cellars

[Glass_A_Day]

Alright all, question about my mini cellars. I have a passive cellar that maintains 50-55 4-5 months out of the year in which I keep all my daily 8-20 dollar bottles. Generally about 10 cases or so. Recently a light bulb lit above my head and I thought, why not move my two mini cellars that I store the big buck wines into the passive cellar. There is plenty of room, my wine is all together, and best of all the mini's won't have to run for 4-5 months cutting down on electricity. Well tonight, about two weeks after the move I go into one mini for a good bottle. Here is the issue. Covering the inside of the door there is moisture. A lot of moisture. Same on cooler two. Now on to the solution. ANy ideas? I was thinking of trying unplugging both and just leaving the doors open. Temp is perfect. I don't feel comfortable with that kind of mositure building up. COudl lead to moldy corks. Any thoughts woudl be great.
