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.

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.
