I had no clue about this!

Keeping your fridge and freezer at the right temperatures is key not just for food safety, but also for energy efficiency and extending the life of your appliance. While the baseline settings are a good start, the actual conditions inside your fridge can fluctuate depending on the season, how full it is, and even how often you open the doors.

Refrigerator: 37°F to 40°F (3°C to 4°C)

Freezer: 0°F (-18°C)

These temperatures slow bacterial growth in the fridge and keep frozen foods safe from spoilage in the freezer. Anything warmer and your food could become unsafe; anything colder and you risk freezing delicate items in your fridge or causing freezer burn.

How to Adjust Your Settings Throughout the Year
Spring and Fall: Minimal Adjustments

These seasons generally have milder ambient temperatures, which means your fridge and freezer don’t have to work as hard. This is a great time to check the internal temperature with an appliance thermometer and fine-tune it if needed. If your fridge is running colder than needed, you can slightly dial it back to save energy.

During the summer months, your kitchen tends to be warmer, and your fridge may get opened more often (think family gatherings, cold drinks, popsicles). Warm air sneaks in, and the appliance has to work harder to stay cool.

Tips:

Set your fridge closer to 37°F to compensate.

Avoid overloading the fridge—it restricts airflow.

Keep cold items like drinks and leftovers covered and placed near the back (coolest part).
