The Ideal Refrigerator Temperature
Wondering what temperature your refrigerator should be? To maintain food safety, your refrigerator should stay at 40 degrees Fahrenheit or below, with 37 degrees Fahrenheit being a good target temperature. At 37 degrees, you have some wiggle room before reaching the 40-degree limit. Keeping your refrigerator within this cold temperature range helps slow the growth of most harmful bacteria, though it doesn’t eliminate it completely. This is why it’s important to maintain a consistent temperature — and handle food properly.
Some refrigerators show the actual temperature on an electronic control panel. Others use a numbered dial that indicates colder or warmer settings without telling you the temperature inside. A refrigerator’s control setting and its actual internal temperature aren’t always the same. To get an accurate read on the internal temperature, use a refrigerator thermometer, an inexpensive way to check whether food is staying at 40 degrees Fahrenheit or below.
Can your refrigerator be too cold? Yes. Temperatures at or below 32 degrees Fahrenheit can cause some foods to freeze, which is why it’s best to aim for around 37 degrees. If food regularly freezes, check the temperature with an appliance thermometer and make sure there isn’t anything blocking the cold air vents.
The Ideal Freezer Temperature
Your freezer temperature should be 0 degrees Fahrenheit. At this temperature, food remains safely frozen while maintaining quality for the recommended storage period.
Frost, Ice and Freezer Burn
If you notice frost or ice on frozen food, don’t automatically turn the freezer temperature up. Frost can form when warm, humid air enters the freezer or when food isn’t wrapped tightly enough.
Freezer burn is another issue that’s easy to blame on temperature. It happens when frozen food loses moisture after being exposed to air. It may leave food dry, discolored or covered with icy patches, but freezer burn is primarily a quality issue rather than a sign that the freezer is too cold.
To help prevent these issues, wrap food tightly or store it in airtight, freezer-safe containers to limit air exposure. Also check the door gasket if you notice unusual frost buildup around the compartment.
How to Check Your Refrigerator and Freezer Temperature
For the refrigerator, look for a reading of 40 degrees Fahrenheit or below. If you’re aiming for 37 degrees and occasionally see a small fluctuation, that doesn’t necessarily indicate a problem. Refrigerators cycle on and off, doors open throughout the day and automatic defrost cycles can temporarily affect temperature.
The freezer should stay at 0 degrees Fahrenheit.
If your refrigerator uses a numbered dial, consult the owner’s manual before adjusting it. Higher numbers don’t mean the same thing on every model, so guessing can leave the compartment warmer or colder than intended.
After changing a setting, allow the appliance time to stabilize before deciding whether another adjustment is necessary. Follow the manufacturer’s instructions for your model and consider an appliance thermometer to ensure more accurate readings.
What If Different Areas of the Refrigerator Feel Colder?
Temperatures can vary inside a refrigerator. Door shelves are exposed to warmer room air every time the door opens, while areas toward the back may stay colder.
Some refrigerators also have specialized drawers with their own temperature settings. A deli, meat or convertible drawer, for example, may operate differently from a standard produce crisper.
If food freezes in the refrigerator compartment or you notice large temperature differences from shelf to shelf, check the appliance temperature and make sure food isn’t blocking vents.
Tips for Maintaining the Ideal Refrigerator Temperature
A few simple habits can help your refrigerator maintain a consistent temperature and keep your food safe:
- Refrigerate leftovers promptly. Refrigerate perishable food within two hours, or within one hour if the temperature is above 90 degrees Fahrenheit.
- Divide large portions. Storing large, hot dishes can potentially affect the refrigerator’s temperature, so divide the dish into shallow containers so they cool faster.
- Keep the door closed. Avoid leaving the refrigerator open longer than necessary. When cooking, gather several ingredients at once to reduce repeated door openings.
- Don’t overpack the refrigerator. Organize food items so that there’s enough space for cold air to circulate and keep large containers from blocking air vents.
- Keep the interior clean. Wipe up spills promptly, especially leaks from raw meat or poultry, and regularly remove spoiled food. Get more refrigerator and freezer cleaning tips.
- Check the door gaskets. Clean the seals regularly and inspect them for cracks, gaps or damage that could let cold air escape.
The Right Temperature for Your Fridge: Recap
Aim for a fridge temperature of about 37 degrees Fahrenheit and a freezer temperature of 0 degrees Fahrenheit. For the refrigerator, the temperature should never be higher than 40 degrees Fahrenheit. To help keep things consistently chilled, consider a refrigerator thermometer, thoughtful food organization and following simple maintenance habits to help catch temperature problems before your groceries go to waste. If your current appliance struggles to maintain the right temperature, it might be time to shop for a new refrigerator. Look for models with convenient features like digital temperature controls to give you a clearer read of the compartment temperature and make it easier to set temperatures to the ideal setting.
