This article will help put everything into perspective - without unnecessary technical terms, but with clear recommendations.
The abbreviation FRZ (from English freezer) means the freezer compartment, and TEMP is an abbreviation for temperature (temperature). Together they form a parameter responsible for the climate in the freezer. But why is this mode highlighted separately, what values are considered normal, and what to do if the refrigerator suddenly starts blinking as an error signal? The answers are below. LG suddenly started blinking FRZ TEMP what is the error signal? The answers are below.
We analyzed the official manuals for models LG series GA-B, GB-B, GC-B, GR- and newer, as well as user reviews to collect up-to-date information. Important: some functions may differ depending on the year of manufacture and region of delivery of the equipment.
What is FRZ TEMP in LG refrigerators: in simple words
FRZ TEMP is an indicator or mode for setting the temperature in the freezer. In most models LG with electronic control (for example, LG GA-B409SLQZ, LG GC-B247SLBV), this parameter is displayed on the display and allows:
- 📊 Control the current temperature in the freezer (usually in the range from
-14°Cto-25°C). - ⚙️ Change the target value manually or automatically (in models with Smart Inverter Compressor).
- ⚠️ Receive warnings about malfunctions (for example, if the temperature rises higher
-12°C).
In refrigerators with a system Total No Frost (for example LG GR-B207SLKZ) FRZ TEMP often works in tandem with FRZ SUPER —an ultra-fast freezing mode. If you see a flashing inscription, this may mean either a normal indication or a signal about the need for intervention.
Please note: in models without a display (for example, LG GA-B329SLQA) this parameter is regulated by a mechanical rotary switch, and the term FRZ TEMP may not be mentioned in the instructions. Instead, the designation Freezer Temp or simply Morozilka.
Optimal FRZ TEMP values: table of recommendations
Manufacturer LG recommends support in the freezer the temperature is from -18°C to -20°C for most products. However, the optimal value depends on what and how long you store. Below is a summary table:
| Type of products | Recommended temperature | Max. shelf life | Notes |
|---|---|---|---|
| Meat (fresh) | -18°C up to -20°C |
6–12 months | When -24°C the period increases up to 18 months |
| Fish and seafood | -20°C up to -22°C |
3–6 months | Fatty varieties (salmon) are stored less |
| Vegetables and fruits | -16°C up to -18°C |
8–12 months | Blanched - up to 14 months |
| Ice cream and desserts | -18°C |
Up to 1 year | When -25°C possible loss of texture |
| Ready meals | -18°C |
1–3 months | Depends on the composition (sauces spoil faster) |
Critical note: if your refrigerator LG supports the mode FRZ SUPER (quick freezing), do not use it constantly. This mode consumes 20-30% more electricity and is intended only for a short-term decrease in temperature when loading new products.
In models with technology DoorCooling+ (for example, LG GC-X247CLAV) the temperature in the freezer can be automatically adjusted when the door is opened frequently. freezer, place an outdoor thermometer (with a range of up to -30°C) between the products for 12 hours. Compare the readings with those displayed on the display - the difference should not exceed 1–2°C. FRZ TEMP spontaneously changes within ±2°C - This is normal operation of the system.
How to set FRZ TEMP: step-by-step instructions
The setting process depends on the refrigerator model Below is a universal instruction for. most LG with electronic control (series GA, GB, GC, GR):
Press the button
Freezer(orFRZ TEMP) on the control panel. In some models you need to hold it for 2-3 seconds.Using buttons
+/-(or▲/▼) set the desired temperature. The change step is usually1°C.Confirm the selection with the button
OKor wait for automatic saving (after 5 seconds).The display will show current value (for example,
FRZ -18°C).
For models with touch control (for example, LG InstaView Door-in-Door):
Touch on the "Freezer" icon → Swipe up/down to change the temperature → Touch on a free area to saveIf after setting FRZ TEMP flashing or beeping, this may mean:
- ❄️ The freezer door is not tightly closed (check the seal).
- ⚡ Power surge (it is recommended to use a stabilizer).
- ❗ Temperature sensor malfunction (diagnostics required).
Make sure that the refrigerator is connected to the power supply
Check that the freezer door is closed tightly
Remove ice from the seal (if any)
Wait 24 hours after first switching on (for new refrigerators)

Frequent errors when working with FRZ TEMP and how to avoid them
Many users encounter problems due to incorrect settings or misunderstanding of the principles of operation of the freezer. Here are the most common errors:
⚠️ Attention: If your refrigerator LG released before 2018, some features FRZ TEMP may work differently. For example, in models without an inverter compressor, the temperature change takes up to 6-8 hours.
1. Installation too low temperature (below -24°C).
This not only increases energy consumption, but can also lead to:
- 🧊 Formation of excessive frost on products (due to sublimation of moisture).
- 🔋 Overloading the compressor and reducing its service life.
- 🍎 Loss of taste of products (for example, meat becomes “dry”).
2. Ignoring the mode FRZ SUPER when loading new products.
If you put warm or fresh foods in the freezer (for example, freshly cooked meat), turn on FRZ SUPER for 2-3 hours. This will prevent:
- 🌡️ Increase in temperature in the chamber and spoilage of already frozen products.
- ☁️ Formation of condensation and ice on the walls.
3. Frequent opening of the door unnecessarily.
Every time you open the freezer, the temperature inside rises by 2–4°C, and the compressor takes time to restore the mode. In refrigerators LG with function Door Alarm When opened for a long time (>1 minute), a sound signal is heard.
What to do if FRZ TEMP shows incorrect values?
If the display displays FRZ -12°C, but the food is frozen more than usual, the problem may be a faulty sensor. Try resetting the settings: unplug the refrigerator for 10 minutes, then turn it on again. If the error persists, contact the service center. In 30% of cases, flashing the electronic module helps.
FRZ TEMP blinks or shows an error: causes and solutions
If the indicator FRZ TEMP flashes, an exclamation mark lights up on the display or a beep sounds, this indicates one of the problems:
| Symptom | Possible cause | Solution |
|---|---|---|
Flashing FRZ TEMP + beep |
Freezer door open >1 minutes | Close the door more tightly. Check the seal for damage. |
FRZ TEMP flashing red |
The temperature in the freezer is higher -12°C |
Check the food load, turn on FRZ SUPER for 2 hours. |
On display ER FF or ER FS |
Malfunction of the freezer sensor | The sensor needs to be replaced (contact service). |
FRZ TEMP does not respond to settings |
The cold supply valve is jammed air | Defrost the refrigerator for 12 hours, then repeat the settings. |
In refrigerators LG with a system Smart Diagnosis (for example, LG GC-B247SLBV) you can clarify the error code:
- Press and hold the button
Ice Plus(orExpress Freeze) for 5 seconds. - Wait until an alphanumeric code appears on the display (for example,
E1 FF). - Compare it with the error table in the instructions or on website LG.
⚠️ Attention: If the problem persists after defrosting, do not try to disassemble the refrigerator yourself. In models with freon FRZ TEMP is preserved, do not try to disassemble the refrigerator yourself. In models with freon R600a (for example, LG GA-B409SLQZ), incorrect intervention may lead to a gas leak.

- 📡 The presence of interference from other household appliances (for example, a microwave).
FAQ: Frequently asked questions about FRZ TEMP in LG refrigerators
Is it possible to turn off the FRZ TEMP indication on the display?
No, in most models LG it is impossible to turn off the freezer temperature display, however, in refrigerators with the function Display Off (for example, LG GC-X247CLAV) you can temporarily. turn off the display backlight by pressing the combination of buttons Lighting + Freezer (hold for 3 seconds).
Why does FRZ TEMP show -18°C, but the food is thawing?
This can happen for several reasons:
- 🔄 Uneven distribution of cold (check that Is the freezer overloaded).
- 🧊 Ice on the evaporator (defrosting required).
- 📉 Fault fan (in models with No Frost).
Try to rearrange the products so that there are gaps between them for air circulation.
How often should you check and adjust FRZ TEMP?
Under normal conditions, it is enough to check the temperature in the freezer once a month. However, adjustment is required in the following cases:
- 🛒 After a large load of products (turn on
FRZ SUPERfor 2-3 hours). - 🌡️ With seasonal changes in room temperature (for example, in the heat of summer).
- ⚡ After power surges in the network.
Does FRZ TEMP affect the energy consumption of the refrigerator?
Yes, the lower the set temperature, the more electricity the refrigerator consumes. For example:
- When
-18°Cthe average consumption is ~1 kW/day. - When
-24°Cconsumption increases to 1.3–1.5 kW/day.
In models with an inverter compressor, the difference is less noticeable (saving up to 30% compared to conventional compressors).
Is it possible to use FRZ TEMP for dry freezing (for example, berries)?
For sublimation drying (dry freezing), a lower temperature is required -30°C, which is not provided by household refrigerators LGHowever, for regular freezing of berries (while maintaining their shape), set FRZ TEMP on -24°C and use the mode FRZ SUPER during the first 12 hours. Arrange the berries on a tray in one layer, then pour into containers.
