Your Freezer’s Dial Isn’t a Temperature Reading
Grocery
A numbered freezer dial tells you which setting you chose. An appliance thermometer tells you the temperature that setting produces. USDA FSIS recommends keeping a freezer at 0°F, about −18°C, for best food quality.
Place a freezer-suitable thermometer where you can check it easily. Follow the appliance instructions for adjusting the control, then allow time for the temperature to settle before checking again.
If the freezer is struggling to stay cold, check that the door shuts completely and that packages aren’t blocking the seal. Keep its manual handy for the recommended loading and ventilation arrangements.
