Set your refrigerator to 37°F (3°C) and your freezer to 0°F (-18°C). That keeps food safe without wasting energy or freezing your produce. Many fridges use a 1–9 dial instead of degrees — here is how to translate it and check the real temperature.
The right numbers
- Refrigerator: 37°F (safe zone is 34–40°F)
- Freezer: 0°F for long-term storage
- Dial 1–9: higher number = colder; start at the middle and adjust
How to check it
Put an appliance thermometer in a glass of water in the middle of the fridge overnight, then read it. Air temperature swings when the door opens, so the water reading is more accurate. Adjust one step at a time and re-check after 24 hours.
If it won’t hold temperature
If the fridge won’t reach 40°F no matter the setting, that’s not a settings problem — it’s usually dirty coils, a failed fan, or a defrost fault. We can diagnose and fix it, with the price up front.
