Even in the "normal" mini fridge, when we first got to room, if it was turned off and we had groceries, I'd stash the food, then put in bags of ice (double bagged) for several hours for the fridge to catch up.
We've learned to always get into the room and check it out, including things like functioning of the fridge (and shower, sinks, TV, etc etc) before we bring any luggage and groceries up to the room (or have Bell Services bring them to the room). Has saved us several times when the fridge was off or there was something else wrong with the room that needed resolving.
