 Marlene in South Carolina wrote in to Team Money Pit and is asking, I'm seeing mold behind the refrigerator in my two-year-old house. Marlene says she pulled the refrigerator out and there was mold on the baseboard. It does have an ice maker, but I see no signs of a water leak. Do I need to call a plumber? Probably not. I think what you're seeing is this. You have warm, moist air that's going to be collecting at the bottom of that refrigerator, and that moisture is going to be enough to feed the mold.
