Our refrigerators are mini (dorm-like) or apartment style refrigerators, these are not like your home refrigerators. If you are putting warm bottled water/pop into refrigerator or filling it full, where no air can circulate through the refrigerator or have the doors open for long period of time filling the refrigerator, you will notice the refrigerator not bouncing back like your home refrigerator does. It will take a long time(6-8 hours) to get back to temperature. Please be sure to bring a cooler and ice for when this does happen or be sure to bring chilled water and pop to avoid this.
