I have this fridge too. A week ago I bent the freezer compartment up to accomodate a keg. There are no obvious exterior cracks in the freezer compartment and there was no obvious gas leakage; however, when I plug it in the fridge will not cool down. There is condensation on the freezer compartment and it will get cool to the touch, but the fridge will not go lower than about 55F. There is a gurgling sound inside like some liquid is circulating, but there is not the gentle hum of the compressor working happily.
I did leave the fridge outside unplugged overnight to let it defrost. I had it covered with a tarp but it did rain overnight. If some water had got in there could that have fried something? I don't know much about fridges (maybe shouldn't have attempted this in the first place) so any help would be much appreciated.
