USDA FSIS recommends keeping appliance thermometers in both fridge and freezer instead of relying solely on a dial. After outages, food safety depends on time, temperature and food type.

Your try-it-at-home checklist

0 / 6 done

1. Obtain two appliance-rated thermometers, one each for refrigerator and freezer.
2. Place them according to product instructions where airflow is not obstructed; avoid the door if it fluctuates markedly.
3. Target 4°C (40°F) or colder for the fridge and approximately -18°C (0°F) or colder for the freezer, subject to local guidance.
4. Allow temperatures to stabilize after loading food or leaving a door open, then recheck.
5. If repeatedly warm, inspect settings, door closure, overpacking and ventilation; contact service if the issue persists.
6. During a power cut use the reading as one clue, but decide food disposal using official time-and-temperature guidance for perishables.
