Deep freezers keep food frozen at or below 0 degrees Fahrenheit, or -18 degrees Celsius. The term “deep freezer” used to mean an appliance with colder temperatures and a faster freezing process than fridge freezers. Today, deep freezers and fridge freezers often cool to the same temperature and at a similar pace.
What Temperature Is Too Low for the Freezer? While it's essential to keep your freezer sufficiently cold to maintain food safety and quality, extremely low temperatures, typically below -20 degrees Fahrenheit (-29 degrees Celsius), can lead to excessive energy consumption and the risk of items freezing too solidly.

The ideal temperature for freezing meat is between -18 and -23 degrees Celsius (0 to -9 degrees Fahrenheit), as recommended by the United States Department of Agriculture (USDA) for safe and optimal storage. At 20 degrees Fahrenheit, the meat will not be at a safe temperature for storage.
The recommended freezer temperature to keep food safe is at or below 0°F (-18°C), making higher temperatures less reliable for long-term freezer storage.
The optimal temperature in a freezer is -18 °C / 0 °F.
This question had me curious about what temperature I should be setting the freezer to and if there's anything I can do to keep my food safe. Here's what I found out. According to the U.S. Food and Drug Administration, the best temperature for your freezer is 0°F (-18°C) or below.
It illustrates that any food with an internal temperature of 40 °F to 140°F is in the temperature danger zone. Refrigerator temperature should be at or below 40 °F and freezer temperature should be zero degrees.
If your freezer is not working, the first thing to check is if the shelves are packed too tightly. Overstuffed freezers can cause an airflow blockage, especially when the evaporator fan is blocked. If your freezer is not cold enough, try clearing off your freezer shelves.
The ideal freezer temperature
The ideal temperature for most household freezers is 0°F (-18°C) or lower. At this temperature, food can be safely stored for an extended period without compromising its quality.
It's pretty easy to remember: Your freezer temperature should be set to a chilly 0° Fahrenheit or below (-18° Celsius or below). Food stored at 0° Fahrenheit or below is safe to eat indefinitely (although quality and taste may be compromised as time passes).
A deep freezer has more space to store frozen food for longer periods than a typical fridge freezer found in your kitchen. Deep freezers are bigger, have a larger storage capacity than fridge freezers. A typical kitchen fridge freezer can start as low as 4 cu.
Ensure maximum air flow and quick, thorough freezing by not overcrowding food on the shelves. The Coldest Spot: The rear center is the coldest spot in a freezer.
To store frozen foods at best quality, keep the freezer set to maintain zero (0 °F or -17.8 °C). Some combination refrigerator-freezers cannot keep the freezer air that cold. As long as foods are solidly frozen, they will stay safe.
Are deep freezers worth it? If you buy food in bulk, have a large family or can't say no to the frozen foods section, deep freezer options are often a worthwhile purchase.
Frost or ice build-up on freezer walls can be one of the signs your freezer is too cold. First, check the temperature setting to make sure it's within a degree of 0ºF (-18ºC) and adjust accordingly. If you notice ice crystals on frozen food, these items may be freezer burned due to colder or fluctuating temps.
Food that won't stay frozen may be an obvious sign of a faulty freezer, but signs like excessive frost build-up on the walls or freezer-burnt food can also indicate unstable freezer temperatures. You may also notice your freezer making unusually loud humming, clicking or buzzing noises as parts struggle to operate.
Deep Freeze Cold Gel works like ice, delivering targeted, rapid cooling, soothing relief for minor aches through gentle application on muscles and joints. Can be used with medicines. Can be used after exercise. SCIENTIFICALLY PROVEN COOLING: Cooling can decrease blood flow and may help calm and soothe the area.
Keep Food Out of the "Danger Zone"
If the temperature is above 90 °F, food should not be left out more than 1 hour. Keep hot food hot—at or above 140 °F. Place cooked food in chafing dishes, preheated steam tables, warming trays, and/or slow cookers. Keep cold food cold—at or below 40 °F.
Freezer - Refrigerator Temperatures
Eat those foods as soon as possible for best quality. Use a free-standing freezer set at 0 °F or below for long-term storage of frozen foods. Keep an appliance thermometer in your freezing compartment or freezer to check the temperature.
Freeze occurs when the temperature drops to 32°-or-lower. A freeze will damage many unprotected plants, especially if the temperature remains at-or-below freezing for several hours.
Reasons your freezer isn't freezing may include:
Dirty condenser coils. Malfunctioning evaporator fan. Broken start relay. Defective electronic controls.
Whilst it is recommended to keep your freezer below -18 degrees Celsius, it is important to not drop the temperature too low. Although 4-star freezers can operate down to -25°C, over time foods frozen at this temperature may start to dry out, causing freezer burn or a loss in quality.
Step-by-step explanation:
-23 degree Celsius more cooler than -15 degree Celsius because in minus the number goes bigger in the negative direction it becomes smaller!!
