prevent condensation of refrigerator cooling line?
I had my refrigerator pulled out today to clean behind it (trying to track down the source of all the little fruit flies we have been having recently, actually), and I noticed a small copper hose, which I assume to be a coolant hose, with frost forming on it. Over the next several minutes as the fridge cycled, frost alternately formed and melted on this hose, causing it to drip on the floor. Obviously any source of un-contained water is a bad thing, especially when behind the fridge or the like where you can't get to it, so I was wondering what, if anything I can do to keep this hose from dripping? As far as I can tell it is just condensate, not leaking or the like. Thanks.
