From your description, I am assuming the unit is cooling and the high temp alarm is not beeping even though the outside of the freezer is hot. It's normal for the freezer to be warm to the touch but not so hot you can't. The reason the outside of the freezer is hot is because that is how the freezer releases the heat from the refrigerant. Unless the freezer is not cooling there is nothing to worry about. If you require further assistance, please respond to the thread with more detail and a complete model number.
