Frequently Asked Questions (FAQs)

1. What is the best thermometer to use in a refrigerator?

The best overall fridge thermometer is the ThermoWorks Fridge/Freezer Thermometer (view at ThermoWorks) because it's a reliable and versatile option. The magnetic thermometer is highly accurate and can be used in both sections of your appliance—or even in a deep freezer.

2. Where is the best place to put a fridge thermometer?

Your refrigerator temperature should be 40 F or less, and your freezer should be 0 F or less. The best place to put a thermometer is in the warmest spot – which would be near the door, not tucked away in the back.

3. How accurate are refrigerator thermometers?

All the models were reasonably accurate when placed in an ice bath and when used in the refrigerator, living up to their manufacturers' claims to measure temperatures within 2 degrees of those recorded by a lab-grade thermocouple.

4. Where do you put a thermometer in a freezer?

Most freezer thermometers should be installed in the center of the freezer without touching anything other than the freezer wall or rack. You should move around frozen food or ice so there's an open space for the thermometer.
