We have, on occasion, taken the side access panel off, but really haven't had to too many times. It doesn't get really hot in NY like the southern, or western states. A battery powered fan on the inside of the fridge works just fine for us. There are some fan units you can buy, that mount under the fridge roof vent, to suck the heat up and out from behind it. Either way, ventilating the back side is a good idea.
