The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
A freezer, according to food safety standards, should be anywhere between -10°F & 10°F. Anything under can risk freezer burn, and anything over can risk bacteria growth.
You can always err on the safe side and lower the temperature below 0°F—your freezer can never be too cold. “Most recommendations are for a range of temperatures but in reality, there is no temperature that is too low for freezers,” says Tetro. “Most freezers do have a lower limit of around -10°F (-23°C).”
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 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 short time limits for home-refrigerated foods will help keep them from spoiling or becoming dangerous to eat. The guidelines for freezer storage are for quality only—frozen foods stored continuously at 0°F (-18°C) or below can be kept indefinitely.
If your freezer is not cold, the problem may be caused by a broken condenser fan motor. The condenser fan draws cool air through the condenser and over your freezer's coils. If this fan is broken, your freezer's inner temperature will rise, and the compressor will overheat.
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.
If your freezer isn't getting cold enough, check the inside of the appliance for layers of frost buildup on the interior walls. If found, break down the ice to release congestion and allow proper airflow.
The temperature selection on a Chest Freezer is made by setting the dial from ONE to SEVEN, with SEVEN being the coldest. The normal safe freezing level is obtained by setting the control on FOUR. Turning the temperature control all the way to the left to the OFF position will turn the power off to the compressor.
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.
Temperature Affects Ice Production
The Refrigerator and icemaker must be at proper temperature. The recommended fresh food temperature is 37° Fahrenheit; the freezer recommended temperature is 0° Fahrenheit. The icemaker must reach about 16°Fahrenheit before a cycle will begin.
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.
Temperature Too Warm
If the freezer is freezing but your ice cream seems to soft, check the temperature setting is correct. The recommended setting for a freezer is 0°F (-18°C). The freezer should be operated in an environment between 55°F (13°C) and 110°F (43°C).
If the garage space is uninsulated or too cold, the freezing temperatures will trick the freezer into thinking it has reached the desired level of refrigeration and it may fail to turn on, which could result in damage to the unit and food spoilage.
Refrigerators do not work as well in the cold as they were designed to work at room temperature. Most of the time, the freezer stops working before the fridge section does. One of the primary culprits behind a malfunctioning garage fridge in winter is the extreme cold temperatures that characterize the season.
Food that is properly frozen and cooked is safe.
Food that is properly handled and stored in the freezer at 0° F (-18° C) will remain safe. While freezing does not kill most bacteria, it does stop bacteria from growing.
To fix a freezer that's not freezing, you'll need to identify the root cause. Common issues include frost buildup, a faulty temperature sensor, or a broken compressor. For accurate diagnosis and repair, it's recommended to hire a service professional.
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
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.
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.
There should be a temperature control inside the refrigerator. (It is probably a turn dial type) This control will adjust the temperature in both the cooler and the freezer. Turn it clockwise to set the temperature colder.
First, cut power to your freezer by unplugging it from the wall or shutting off power to the proper control panel switch. Then reset the freezer's control panel by lowering it to zero or using a shut-off switch. Consult your user manual for specifics on navigating the control panel.
