Any ideas why, when I turn my upright freezer on, the outside of the box becomes so hot you can't touch it. I recently charged the freezer. Could using too much refrigerant be the cause of it creating so much exterior heat? I never performed a vacuum on it, however it does freeze inside the box. You can turn it off with the temperature control which has a range from 1 to 6. I tried the lowest settings-1-, but that doesn't make a difference. The compressor doesn't seem to stop or cycle. Help! Anyone.
