Hi Espatag1. Yes, they do that. It's only condensation and there's little you can do to stop it. Just empty it out regularly, preferably first thing in the morning when the air temperature will be low and the food inside at its coldest. Just remember to put your plastic boxes in the bottom, not the paper bags of bacon or sausages.
Only tip I know is not to overfill it so that the air can circulate easily and chill the contents. Pretty much opposite to using icepacks where you normally pack as much cold stuff in as possible
got so fed up with that plus the terrible noise at night that we bought a cheap small minibar type fridge, not a beer cooler, an actual fridge that even has a small freezer compartment in the top, never looked back.
