Many owners of modern appliances mistakenly believe that the question of how to defrost an LG two-chamber refrigerator is not relevant for them due to the introduction of advanced cooling technologies. Indeed, the No Frost i Total No Frost systems greatly simplify life by automatically removing condensate and preventing the formation of an ice crust on the walls. However, even the most advanced units require periodic complete disconnection from the network to carry out deep sanitization and maintenance of hidden components.
Ignoring this procedure can lead to a decrease in the efficiency of the compressor, the appearance of unpleasant odors and even breakdown of the water drainage system. Unlike older models with a drip system, here the process has its own technical nuances that must be taken into account so as not to damage sensitive electronics or plastic elements of the case. The correct approach to defrosting extends the life of the device and guarantees the freshness of your products.
In this article we will analyze in detail the algorithm of actions for LG dual-chamber models, explain why automation does not replace manual cleaning, and provide checklists for safe work. You will find out how often you really need to do this and what tools you will need for a high-quality result.
Do you need to defrost LG refrigerators with the No Frost system
There is a persistent myth that equipment marked No Frost does not require defrosting at all. This is not entirely true: the system prevents ice build-up on products and shelves, but does not eliminate the need for hygienic maintenance. The internal evaporator, hidden behind the back panel of the freezer, is still covered with a microscopic layer of frost, which over time turns into an ice coat. If this layer becomes too thick, heat transfer efficiency will decrease and the compressor will wear out.
In addition, dust, bacteria and mold accumulate in the drainage channels and condensate tray over time, which the self-cleaning system is not able to remove. That is why manufacturers recommend carrying out complete defrosting at least once a year, even if ice is not visually visible anywhere. For models with a fresh zone Fresh Zone or Multi Air Flow cleanliness of the air ducts is critical for proper flow circulation.
It is important to understand the difference between automatic defrosting of the evaporator, which is carried out by the device itself every few hours, and complete manual defrosting of the entire volume. The first is the work cycle, the second is a preventive measure. If you notice that the refrigerator begins to hum louder than usual or takes longer to gain temperature after opening the door, this is a sure sign that heat exchange is disrupted and intervention is required.
Preparation for the procedure: tools and safety
Before you start the process, you need to properly prepare so as not to spoil the floor covering or damage the internal components. You will need not only free time, but also a certain set of supplies. Safety should be a priority: any manipulation with an electrical appliance begins with turning off the power.
Gather the following items for effective work:
- 🧽 Soft sponges and microfiber for wiping internal surfaces without scratches.
- 🧴 Specialized refrigerator cleaner or baking soda solution (1 tablespoon per liter of water).
- 🧺 Several dry towels and a basin to collect draining water.
- 🧹 A vacuum cleaner with a narrow nozzle for cleaning the rear condenser grille.
- 🧤 Rubber gloves to protect the skin of your hands from detergents means.
It is strictly forbidden to use sharp objects, such as knives or screwdrivers, to chip ice, even if you find a frozen area in a hard-to-reach place. The plastic in modern LG models is quite fragile and can crack from mechanical stress, which will lead to depressurization of the cameras. It is also not recommended to use hair dryers or heaters to speed up the process, since a sudden temperature change can damage the plastic case and seals.
⚠️ Attention: Never plug in the refrigerator if there is still water or high humidity inside. This may cause a short circuit in the electrical control circuit.
Determine in advance the location for storing food. If it’s winter outside, you can take perishable goods to the balcony (provided that the temperature there is not lower than +5°C for the refrigerator compartment, so as not to spoil the food, or use thermal bags). For the freezer, it is better to prepare containers with ice to maintain the temperature during cleaning.
Step-by-step instructions: how to defrost a two-chamber LG refrigerator
The process of defrosting a two-chamber LG unit requires consistency. First the refrigerator compartment is emptied, then the freezer compartment. This allows you to minimize the loss of cold and makes it easier to access the internal elements.
Perform the steps in the following order:
- Disconnect the device from the power supply by unplugging the plug from the socket. Do not rely solely on the off button on the cabinet.
- Remove all products, shelves and drawers. Wash glass shelves separately with warm water to prevent them from bursting due to temperature changes.
- Leave the doors open for natural thawing. Place towels on the floor in front of the doors to absorb moisture.
- Wait until the water has completely drained. In LG models, water usually flows into the drainage hole, but if there is excessive melting, manual collection may be required.
- Rinse the internal surfaces with the prepared solution, paying attention to the corners and seals.
☑️ Checklist for proper defrosting
Pay special attention to the drainage hole in the refrigerator compartment. It often becomes clogged with crumbs and mucus, causing water to flow into the chamber or onto the floor. You can clean it using a special flexible brush or soft wire wrapped in cotton wool. After cleaning, pour in a little clean water to make sure that it flows freely into the capillary tube.
Features of caring for the freezer and No Frost zone
The freezer in LG two-chamber refrigerators is often equipped with a system No Frost, which implies the presence of a hidden evaporator and fan. It is impossible to get to them without disassembling the case, but you can make their work easier. In some models, access to the filter or air exhaust duct can be gained by removing the rear plastic panel inside the freezer.
If you decide to remove the panel (which is not necessary for normal defrosting, but useful for deep cleaning), proceed carefully:
- ❄️ Unscrew the mounting screws, if any (they are often hidden under plugs).
- ❄️ Carefully snap off the plastic clips around the perimeter.
- ❄️ Check the condition of the evaporator: if it is covered with a thick layer of ice, the defrost heating element or sensor may be faulty.
- ❄️ Wipe fan blades with a dry cloth, removing dust.
After cleaning, reassemble the structure in reverse order. Make sure that all the latches are in place, otherwise air circulation may be disrupted and the temperature in the chamber will no longer be maintained. In zones Linear Cooling it is important not to damage temperature sensors, which may be located in visible places.
| System element | Check frequency | Cleaning method | Risk ignoring |
|---|---|---|---|
| Drainage hole | Every defrosting | Washing with water, cleaning with a brush | Puddles inside the chamber |
| Door seals | Once every 3 months | Wipe with soda solution | Loss of tightness, ice |
| Condenser (rear) | Once a year | Vacuum cleaner or dry brush | Compressor overheating |
| Fan (inside) | During deep cleaning | Dry wiping | Noise, poor circulation |
If, when removing the panel, you find a massive ice cocoon on the evaporator, this is a signal of a malfunction. Normally the ice should melt completely during defrost cycles. The presence of “icicles” or blocks of ice requires calling a technician to diagnose the sensors or heater.
Elimination of unpleasant odors after defrosting
Often after defrosting, owners are faced with the problem of lingering odors. This is due to the fact that along with water, stagnant food aromas rise from porous plastic surfaces and seals. To get rid of them, ordinary water is not enough.
Use proven folk or professional remedies:
⚠️ Attention: Do not use chlorine-containing products or aggressive chemicals with a strong aroma. The plastic of the refrigerator easily absorbs odors, and it will be extremely difficult to remove them later.
Absorbents work most effectively. Place open containers with activated carbon, ground coffee or soda on the shelves. These substances perfectly absorb foreign molecules from the air. You can also wipe the surfaces with a solution of citric acid or vinegar (in a weak concentration), which neutralize bacteria.
Why does the smell return after a week?
If after a thorough washing the smell returns, it means the source is in a hard-to-reach place, for example, in a drainage hose or under the sheathing. Disassembly and professional sanitation are required.
Do not forget about egg containers and bottle shelves - dirt often accumulates in their structural elements. Take them out, rinse them under running water and dry them thoroughly before putting them back. The cleanliness of these little things directly affects the overall hygienic background.
Correct switching on and first start-up
After the refrigerator has been washed and wiped dry, you should not immediately load it with food. The equipment should stand with the doors open for another 30-60 minutes after the end of washing so that the moisture completely evaporates. Then collect all the drawers and shelves.
Plug in the empty refrigerator. Let it idle for at least 2 hours (preferably 3-4 hours) until it reaches operating temperature. Only after the sensors detect the desired cold and the compressor turns off, you can add food. This is especially important for two-chamber models, where it takes time to stabilize the temperature in both chambers.
Make the first load gradually. Do not place warm foods and do not fill the volume completely at once - this will put extra load on the compressor. Arrange the food evenly, without closing the ventilation holes through which cold air circulates.
Common mistakes when defrosting and how to avoid them
Even experienced users sometimes make mistakes that can shorten the life of expensive LG equipment. One of the most common is an attempt to speed up the process using hot water or a hairdryer. Sharp heating of the plastic leads to its deformation and the appearance of microcracks, which grow over time.
Another mistake is ignoring the instructions for a specific model. Some LG refrigerators have electronic controls that must be put into transport or diagnostic mode before defrosting, although most modern models simply require physical unplugging. Always check the manual.
Also, do not leave the refrigerator to defrost in the sun or near heating appliances. Melting evenly at room temperature is the safest option. If you live in a private house and take the refrigerator outside in winter, make sure that the temperature does not drop below +5°C, otherwise the oil in the compressor may thicken, which is dangerous when first started.
How long does defrosting take on average?
For a two-chamber LG refrigerator, the volumetric process of complete defrosting takes from 3 to 5 hours. It all depends on the amount of ice and room temperature. Do not try to artificially speed up this process.
Is it possible to wash the refrigerator with soapy water?
Using regular soap is not recommended, as it leaves a film and odor. It is better to use special products for household appliances or a baking soda solution, which is safe and does not require careful rinsing.
What to do if the refrigerator does not freeze after defrosting?
If after turning on and waiting for 5-6 hours the temperature does not drop, the circuit may have been damaged during defrosting or the electronics have been flooded. Check that the doors are closed tightly and that the fan is running. If there is no noise or the compressor is humming, but there is no cold, call a technician.
Do you need to lubricate the seals after washing?
Yes, this will extend their life. After drying, wipe the rubber seals with silicone grease or glycerin. This will prevent them from drying out and cracking, while maintaining tightness.
Is defrosting dangerous in the summer heat?
In the summer the process will go faster, but there is a risk that the products will spoil while they are outside the refrigerator. Plan defrosting for the evening or at night, when the room temperature is lower, or use refrigeration elements for a portable container.
