Restoring the operation of refrigeration equipment after clearing ice is a procedure that requires strict adherence to time intervals and sequence of actions. Incorrect start the unit can lead to compressor failure or disruption of refrigerant circulation. Many owners of equipment LG make the mistake of starting operation immediately after removing the water, which is categorically unacceptable.
Modern models of the Korean brand, including systems Total No Frost and Smart Inverter, are equipped with complex electronics and sensitive sensors. Moisture remaining in hard-to-reach places can cause a short circuit during a sudden start. Therefore, before pressing the power button, you need to make sure that all internal components are completely dry and warmed up to room temperature.
This article describes in detail the algorithm of actions that will allow you to safely return the equipment LG to operating mode. We will look at the waiting time frame, the procedure for checking the condensate drainage system and the features of setting temperature conditions for different chambers.
Time interval before starting the equipment
The main question that worries users concerns the duration of the pause between the end of washing and turning on the network. The minimum time that the refrigerator should remain turned off LGis 4 hours. This period is necessary for the complete evaporation of moisture from the electrical contacts and warming up the oil in the compressor.
If defrosting was carried out in winter or the unit was transported at low temperatures, the waiting time increases to 8–12 hours. The oil in the compressor thickens when cold, and an attempt to start the motor immediately will result in operation in “dry friction” mode, which critically reduces the life of the mechanical part mechanical part.
⚠️ Attention: An attempt to turn on the refrigerator less than 2 hours after defrosting may cause the start relay protection to trip or windings to fail. engine.
It is important to consider that different models LG have different insulation designs. In budget series with a drip system, drying may take longer due to the location of the evaporator. While premium lines with technology DoorCooling+ require thorough drying of the air duct area.
Preparing for the first turn on after inactivity
Before connecting the power cord to the outlet, it is necessary to conduct a visual inspection of the internal space. Make sure there is no liquid left in the drainage holes or grooves. For models LG
Check the condition of the rubber seals on the doors. After prolonged washing, they may be damp, which will impair the seal when first closed. Wipe them with a dry cloth and make sure there are no creases. This is critical for the correct operation of the cooling system.
- 🧹 Thoroughly wipe all shelves, drawers and inner walls of the chambers with a dry cloth.
- 🔌 Inspect the power cord for damage to the insulation or oxidation of the plug contacts.
- 🌬️ Make sure that the ventilation grilles at the back of the unit are free of dust and foreign objects.
- ⚖️ Check the stability of the refrigerator on the floor, adjust the support legs if necessary.
Pay special attention to the area around the compressor at the bottom of the device. If water gets in during washing, use a hairdryer on cool air or just wait until it dries completely. Turning on a wet compressor is a direct path to expensive repairs.
Step-by-step instructions for starting an LG refrigerator
The process of activating equipment LG after defrosting has its own nuances, depending on the type of control. Unlike old mechanical models, modern units require the correct sequence of power supply and mode settings.
☑️ Checklist for starting a refrigerator
First, connect the power cord to a working outlet with mandatory grounding. Do not use extension cords or tees as compressor starting currents may be high. After connection, you will hear a characteristic click - this is the start relay. Smart Inverter may be high. After connecting, you will hear a characteristic click - this means the starting relay has activated.
The lights on the display or indication panel will light up, and the self-diagnosis process will begin. The electronic control unit will check the condition of the temperature sensors and the integrity of the circuits. At this moment, do not open the doors so as not to disturb the calibration of the sensors.
⚠️ Attention: If after turning on you hear a loud knock or buzz that does not stop after 5-10 seconds, immediately unplug the device.
For models with touch controls, the initial setup may take several minutes. The system may offer to reset the settings to factory defaults if previous data was lost during a long shutdown. Agree with this in order to avoid conflicts in the operation of the algorithms.
Why does the refrigerator hum after it is turned on?
Humming in the first 15–20 minutes of operation is a normal process of the compressor reaching operating mode and the refrigerant circulating through the system. If the sound is monotonous and is not accompanied by vibration of the body, there is no need to worry. However, if the hum turns into a clanging or whistling sound, this is a sign of a mechanical malfunction.
Setting temperature modes and functions
After successful startup and passing the initial diagnostics, it is necessary to set the optimal operating parameters. By default, equipment LG often offers standard values, but after defrosting it is better to set the intensive cooling mode to quickly stabilize the temperature.
Use the control panel to select the mode Express Freeze (Quick freezing) in the freezer compartment. This will force the compressor to work at maximum power for several hours, which will help quickly gain cold after inactivity. In the refrigerator compartment, set the temperature to +3...+4°C.
If your model supports control via Wi-Fi and the application LG ThinQ, check the device status in your smartphone. Sometimes, after a long shutdown, re-authorization or a firmware update is required for correct operation of smart functions.
| Operating mode | Temperature (HC) | Temperature (MK) | Recommendation |
|---|---|---|---|
| Standard | +3°C | -18°C | For daily use |
| Eco | +5°C | -15°C | At minimum load |
| Fast cooling | +2°C | -24°C | Immediately after defrosting |
| Holiday | +15°C | Off | Only for the refrigerator compartment |
Remember to activate the function Child Lock (Child Lock) if There are small children in the house who may accidentally change the settings during active cooling. This will prevent unintentional changes to the parameters.
Diagnostics of possible problems at startup
Even if all the rules are followed, abnormal situations may arise after defrosting. Often users are faced with the fact that the refrigerator turns on, but does not get cold. In systems No Frost this may indicate freezing of moisture in the melt water drainage channel, which has not had time to dry.
Another common problem is the constant operation of the compressor without shutting down. This happens if the temperature sensor inside the chamber has not yet cooled down to the set value. Let the unit run idle for 2-3 hours before drawing conclusions about the malfunction.
- ❄️ Ice build-up on the back wall in the first hours - a sign of residual moisture in the system.
- 🔊 Extraneous sounds (gurgling, hissing) - normal movement of freon through the pipes.
- 💡 Flashing indicators —a signal about the need to check the door tightness or sensor failure.
If an error code appears on the display (for example, rF, dH or Er FF), refer to the instructions. Often these codes indicate evaporator defrost problems that may have been made worse by improper manual defrosting.
Loading with products and entering operating mode
Complete cooling of the internal volume to stable values takes from 4 to 8 hours, depending on the model and the ambient temperature in the room. It is not recommended to load food before this time, since warm food will put additional load on the compressor.
Start filling the chambers gradually. First, place the food in the freezer until it reaches -18°C before filling the refrigerator compartment. Uniform distribution of products will ensure proper circulation of air flow.
On the first day of operation, try not to open the doors unless absolutely necessary. This will allow the system to stabilize the temperature background and form the correct supply of cold in the evaporator. Models LG with a linear compressor are characterized by a quiet start, so do not be alarmed if the unit operates almost silently.
⚠️ Attention: Interfaces and button locations may vary depending on the specific series and year of manufacture of the LG refrigerator. Always check the user manual supplied with your model.
Following these simple rules will extend the life of your refrigerator LG and avoid costly repairs. Proper operation after defrosting is the key to stable preservation of food freshness for many years.
Frequently asked questions (FAQ)
Is it possible to turn on the LG refrigerator immediately after defrosting, if you really need to?
It is strictly not recommended. Even if there is no visual moisture, condensation in electrical circuits and thickened oil in the compressor can lead to breakdown. The minimum waiting period is 4 hours, otherwise you risk damaging the equipment forever.
Why does the LG refrigerator make gurgling sounds after turning on?
This is a normal physical process. The refrigerant (freon) begins to circulate through the pipe system, moving from liquid to gaseous and back. The sounds can last from several minutes to an hour until the pressure in the system completely stabilizes.
How long does it take for an LG refrigerator to get cold after defrosting?
Initial cooling to operating temperatures usually takes 2-3 hours. However, to completely stabilize the temperature in all points of the chambers and form a reserve of cold, up to 24 hours of continuous operation without loading food is required.
What to do if the defrost light comes on after defrosting?
In some models LG the defrost indicator may light for some time after turning on until the system check the condition of the evaporator heating element. If the indicator does not go out after 2-3 cycles of operation or flashes with a certain frequency, this is a signal about a malfunction of the defrost sensor.
