It's not just the values that have issues with the frigdes not getting really cold. Anytime the room fridge is inside of a cabinet, there is not enough air flow for the fridge to be efficient. We have gotten around this by leaving the cabinet door open anytime we are not actively milling around the room. When we leave for the parks or are sleeping, we leave it open all the way. We packed our fridge with warm water bottles, left for the day and when we came back they were ICE cold!
