Modern LG refrigerators are equipped with many functions, the names of which in English can confuse the average user. One of the most common mysteries is the inscription Freeze Tempappearing on the control panel. Many equipment owners mistakenly believe that this is some kind of special emergency freezing program, although in reality everything is much simpler.
In fact, this parameter is responsible for setting and displaying the temperature in the freezer. Understanding how this setting works allows you not only to save energy, but also to extend the shelf life of products, maintaining their structure and taste. In this article, we will analyze in detail how to control this parameter and what values are optimal for different situations.
Incorrect setting of the mode can lead to spoilage of products or, conversely, to their freezing, which makes them unsuitable for consumption. Having understood the nuances of the system No Frost and electronic control, you can configure your refrigerator so that it works as efficiently as possible.
Deciphering the Freeze Temp function
The term Freeze Temp literally translates as “freezing temperature”. On LG refrigerator displays, this text indicates the current operating mode of the freezer compartment or allows the user to change the target temperature value. When this inscription is lit on the screen, you are in the cold setting menu for the lower chamber (or upper, depending on the layout of the model).
It is important to distinguish this function from the mode Express Freeze (Express freezing). If Freeze Temp is a static setting that you set once to constantly maintain the climate, then express mode is a temporary function for quickly cooling a large volume of fresh food. After activating the express mode, the refrigerator usually operates at maximum for several hours, and then automatically returns to the set value Freeze Temp.
⚠️ Attention: Do not confuse the temperature setting indicator with the malfunction indicator. If the Freeze Temp inscription flashes along with a sound signal, this may indicate an increase in the temperature in the chamber above the permissible norms.
The control system in LG models is designed in such a way that the user can easily switch between the settings of the refrigerator (Fridge Temp) and freezer compartments. Typically, a separate button or a long press on the temperature selection button is used to switch between them.
Optimal temperature conditions for storage
Choosing the right temperature is a key factor in the safety of products. The standard value for most freezers is -18°C. It is at this temperature that most bacteria and microorganisms enter a state of suspended animation, which allows you to store meat, fish and vegetables for a long time without loss of quality.
However, depending on your needs, the setting range Freeze Temp in LG refrigerators usually varies from -15°C to -23°C. Lower temperatures (for example, -20°C or -23°C) are advisable if you plan to store food for a very long time, more than 3-4 months. This is especially true for berries, mushrooms and semi-finished meat products.
- ❄️ -15°C: Permissible minimum, suitable for short-term storage (up to 2-3 weeks) or if the refrigerator is heavily loaded and you need to reduce the load on the compressor.
- ❄️ -18°C: Gold standard recommended by manufacturers for daily use and storage of most frozen foods.
- ❄️ -20°C and below: Deep freezing mode is ideal for long-term storage of stocks prepared during the harvest season or purchased in bulk.
It is worth considering that a decrease in temperature below -18°C leads to an increase in energy consumption. A difference of 1 degree may seem insignificant, but in terms of a year of operation, the electricity bill can increase significantly. Therefore, unless absolutely necessary, keeping the value Freeze Temp at a minimum (-23°C) is not recommended.
Instructions: how to change the freezing temperature
The setting process may vary slightly depending on the series of your LG refrigerator (for example DoorCooling+, InstaView or classic models with a display on the door). However, the general algorithm of actions remains the same for most electronically controlled devices.
First you need to unlock the control panel if the lock indicator on it is on. This usually requires pressing and holding a button Lock or a combination of buttons for 3 seconds. After removing the lock, you can begin adjusting the parameters.
☑️ Freeze Temp setting algorithm
Next, find the button labeled as Freeze Temp or simply Freeze. Press it cyclically. The numbers on the display will change: -15, -16, -17, -18 and so on. The selected value will begin to flash, indicating that the system is waiting for confirmation or to enter standby mode.
Once you have settled on the desired value, do not touch the control panel for 5-10 seconds. The system will automatically remember your choice and the blinking will stop. Now the compressor will start working in a new mode until the set parameters inside the chamber are reached.
⚠️ Attention: The interface of touch panels may vary. On some LG models with Smart ThinQ temperature control is also available through a mobile app, which can be more convenient than pressing buttons on the door.
Table of values and their impact on products
Understanding how different temperatures affect specific types of products helps optimize space and energy. Below is a table showing the dependence of the shelf life on the selected value Freeze Temp.
| Temperature (°C) | Operating mode | Recommended products | Max. shelf life |
|---|---|---|---|
| -15°C | Economical | Ready semi-finished products, bread, ice cream | up to 3 weeks |
| -18°C | Standard | Meat, fish, poultry, vegetables, berries | up to 3 months |
| -20°C | Intensive | Game, seafood, preparations for a year | up to 6-8 months |
| -23°C | Maximum | Long-term storage of any products | more than 1 year |
Please note that the shelf life is indicated for products that were frozen correctly and were not defrosted during storage. Violating the temperature regime even for a short time can significantly reduce these times.
Why can’t you change the temperature often?
Frequently changing the Freeze Temp settings causes the compressor to work in abnormal mode. Sudden changes in temperature inside the chamber lead to the formation of condensation on products, which turns into an ice crust, deteriorating the quality of food.
Features of operation in different conditions
The effectiveness of the function Freeze Temp directly depends on environmental conditions. If the refrigerator is installed in a hot room or near heating devices, the system will have to work harder to maintain the set -18°C. In such cases, the electronics may temporarily limit the ability to set temperatures too low to protect the compressor.
It is also important to consider the load level of the freezer. An empty refrigerator loses cold faster when the door is opened, but it also restores temperature faster. A full chamber holds the cold better (the effect of the “heat capacity” of frozen products), however, for the initial cooling of a large volume of fresh food, it is better to temporarily activate the mode Express Freezeand then return to standard settings Freeze Temp.
In models with the system Linear Cooling from LG, temperature fluctuations are minimal (±0.5°C), which allows products to stay fresh longer. In such devices, the Freeze Temp setting is very precise, and a change in value of even 1 degree will be noticeable to the system.
- 🌡️ Summer period: In hot weather, it is recommended not to lower the temperature below -18°C unless necessary, so as not to overload the condenser.
- 🌡️ Winter period: If the refrigerator is located in an unheated room, make sure that the model supports operation at low ambient temperatures (climate class).
- 🌡️ Loading food: When loading more than 2 kg of fresh food per 10 liters of chamber volume, use the enhanced freezing mode.
Possible problems and solutions
Sometimes users are faced with a situation where the set value Freeze Temp is not reached or the indicator starts flashing. This may indicate a loose door seal, dirty vents, or a faulty temperature sensor.
The first thing to do is to check if there is anything blocking the door from closing and if the seal is clean. You should also make sure that the food does not block the ventilation holes through which cold air enters the chamber. In refrigerators No Frost air circulation is critical.
⚠️ Attention: If, after checking the tightness and cleaning the ventilation ducts, the temperature does not return within 24 hours, and the indicator continues to flash, you must contact an authorized service center. Self-repair of the refrigerant system is prohibited.
Another common problem is ice freezing even with a system. No Frost. This often happens if the door has been open for a long time or hot food has been placed in the chamber. In this case, defrosting the refrigerator (disconnecting from the network for 10-12 hours) and subsequent correct settings will help. Freeze Temp.
What to do if the Freeze Temp button does not responds?
If pressing the button does not cause changes on the display, most likely the control panel lock is activated (Child Lock). Find the button with the image of a lock or the signature Lock and hold it for 3-5 seconds until the corresponding sound signal appears or the lock icon disappears on the screen. After this, temperature control will become available.
Is it possible to store medicines in the freezer at -18°C?
You can store medicines in the freezer only if this is directly stated in the instructions for the drug. When frozen, most medications lose their properties or change their chemical composition. The Freeze Temp mode is intended exclusively for food products.
Why is the temperature in the freezer higher than the set one?
If you set it to -18°C, and the thermometer shows -12°C, there may be several reasons: a malfunction of the temperature sensor, a freon leak, a breakdown of the blower fan or compressor. Also check if the melt water drain channel is not clogged, which is typical for No Frost systems.
How to reset Freeze Temp settings to factory settings?
In most LG models, a full reset occurs when the refrigerator is disconnected from the power supply for 10-15 minutes. After turning on, the device will return to the standard factory settings, usually -18°C or -19°C for the freezer and +3°C for the refrigerator.
