I bought a mini fridge just the other day. I plugged it in and within the hour it was cold and i refriderated cereal bars which were kept cold at a high standard. But literally 24 hours later of instalation when i opened the door there was a puddle of water inside and some on the outside. I dried it all and waited an hour to find another smaller puddle had appeared. Could this be a problem or just the fridge getting started?
