Congratulations, Melissa, on your new Scamp!
In this case, just picked up and do not know if electric is really working, it seems, you might let the refrigerator
and freezer go to room temp. Then turn on the refrigerator
again. In an hour or two, it should be obvious that the freezer is working. I would not expect the refrigerator
to take 18 hours, however, it does take many hours to get a proper temp. That is why people often turn it on the day before. I assume you have put it on electric setting as mentioned above.
