The Best Refrigerator Temperature to Keep Food Fresh

On February 16, 2025 By newsroom Topic: Food Guide

Proper fridge and freezer temperatures are crucial for keeping food fresh and safe. Here’s everything you need to know, including expert testing insights from Consumer Reports.


Optimal Temperatures

  • Refrigerator: 37°F (ideal for preserving freshness without freezing).
  • Freezer: 0°F (perfect for keeping foods thoroughly frozen).

Challenges with Refrigerator Controls

  • Many fridges have numerical settings (1-5), which can be imprecise.
  • Even digital controls may not display accurate temperatures.
  • CR tests have found variances of up to 5°F, which can mean the difference between fresh or spoiled food.

How Experts Test Refrigerator Temperatures

Simulated Home Environment: Tests are conducted in a 70°F climate-controlled lab.

Precise Measurements:
- Fridge is set to maintain 36°F to 38°F.
- Freezer is set between -1°F to 1°F.

Findings:
- Some fridges maintain consistent temperatures perfectly.
- Others deviate significantly from the ideal, requiring user adjustments.


Setting the Correct Temperature for Your Fridge and Freezer in Summer

Keeping your refrigerator and freezer temperatures in check during the hotter months is essential for food safety and efficiency. Here's how to ensure optimal cooling:


Key Temperature Settings

  • Fridge: Set to 35°F to 38°F to keep food fresh without freezing.
  • Freezer: Set to 0°F for thorough freezing and food preservation.

Steps to Ensure Proper Temperature

Check the Thermostat
- Locate the fridge’s thermostat control.
- Confirm it’s set within the recommended range (35°F to 38°F).

Use a Refrigerator Thermometer
- Place a thermometer in the fridge and freezer.
- Check readings regularly to ensure accurate cooling.
- Adjust the thermostat as needed if the internal temperature is off.

Account for Summer Heat
- Compensate for Frequent Use: With more door openings and ambient heat, internal temperatures can rise.
- Make Small Adjustments: Slightly lower the thermostat to maintain consistent cooling during high temperatures.


Additional Tips for Summer

  • Inspect Door Seals: Ensure seals are tight to prevent cool air from escaping.
  • Limit Door Openings: Keep doors closed as much as possible to retain cool air.
  • Avoid Overloading: Allow airflow inside the fridge and freezer for efficient cooling.

By following these tips, your fridge and freezer will stay efficient, and your food will remain fresh even during the summer heat!
