To What Temperature Should I Set My Upright Freezer? To What Temperature Should I Set My Upright Freezer?
If you have an upright freezer, you will need to keep the temperature regulated to minus 10 degrees Fahrenheit. To be sure it is set correctly, and calibrated, pick up another thermometer at a hardware or home improvement store. Attach it with some wire or string beside of the upright freezer's thermometer. Check to be sure both are at the same temperature after 24 hours. If your upright freezer is warmer than the thermometer, you may lower the temperature. If it is colder, then you will not have to do anything. Check the thermometers monthly to be sure it is running cold enough to keep foods safe.
