Modern refrigerators of the Swedish brand Electrolux are famous for their reliability and thoughtful functionality, but even the most advanced equipment requires periodic maintenance. Many owners mistakenly believe that the presence of the system No Frost completely eliminates the need to defrost the unit, but this is not entirely true. Although ice crust does not form on the walls in such models, hygienic cleaning and defrosting of the evaporator must still be carried out at least once a year to maintain the efficiency of the compressor.
If your model uses a drip system or a mixed type of cooling, then ignoring the ice removal procedure can lead to serious consequences. Frost buildup creates additional load on the engine, increases electricity consumption and can cause thermostat failure. In this article, we will look in detail at how to safely and quickly carry out the procedure for various models so that your refrigerator serves for many years without breakdowns.
Incorrect actions during defrosting, such as using sharp objects to chip ice or sudden temperature changes, can cause irreparable damage to the cooling circuit. Damage to the evaporator tubes during mechanical cleaning of ice is the most common cause of expensive repairs, which are often cost-effective is impractical. Therefore, it is extremely important to follow proven algorithms and not try to speed up the process with aggressive methods that can break the tightness of the system.
Determining the type of cooling system of your refrigerator
Before starting any manipulations, you must clearly understand what kind of cooling system you are dealing with, since the approach to maintenance will be different. In the line Electrolux most often there are three types: Full No Frost, where air circulates through special channels and does not come into direct contact with products; drip system (Direct Cool), in which moisture flows down the back wall; and combined, where there are droplets in the refrigerator compartment and No Frost in the freezer.
You can determine the type of system by looking at the technical data sheet of the device or carefully examining the interior of the chambers. If you see that the back wall of the freezer is covered with a plastic panel with vertical slits, and there is no visible groove at the bottom for water drainage, then you are facing No Frost. In these models, ice freezes on a hidden evaporator and the water evaporates automatically, but dust and bacteria accumulate over time.
⚠️ Attention: Do not rely solely on the presence of ice as an indicator of the type of system. In Low Frost or Smart Frost models, ice can build up slowly, creating the illusion of complete automation, but manual defrosting is required for them once every 6-8 months.
Models with a drip system are characterized by the presence of a visible evaporator (often an aluminum plate or tubes) on the back wall, which periodically becomes covered with frost and then melts. It is these units that require the most careful attention to the defrosting procedure, since ice here can block the outflow of water and create a “fur coat” that will interfere with the operation of thermostat.
Preparatory stage: turning off and removing products
The beginning of the defrosting process requires careful preparation to minimize risk of food spoilage and floor contamination. The first step is to empty the cells of their contents by putting the food in basins with cold water, thermal containers, or, if it’s winter outside, on the balcony. It is important to make sure that the storage temperature of products does not exceed critical values, especially for meat and fish, so try to carry out the procedure in the cool season or as quickly as possible.
After emptying the shelves, you should disconnect the refrigerator from the power supply. Don’t just unplug the cord from the outlet, but first move the temperature regulator to the “0” or “Off” position, if such a function is provided by the design of your Electrolux. This will avoid a voltage surge in the control system when switched on again. Then carefully remove all removable elements: drawers, shelves, containers for vegetables, which must be washed separately with warm water and a mild detergent.
- 🧊 Prepare flat containers with low sides to collect melting water, since there is usually no regular drain in the freezer.
- 🧽 Stock up on soft sponges in advance, microfiber and neutral detergent without abrasive particles.
- 📦 Find a place for temporary storage of products where the temperature will remain low for 3-5 hours.
- 🧤 Prepare rubber gloves to protect the skin of your hands from the effects of detergents and cold residues.
Pay special attention floor covering around the refrigerator. Cover the floor with thick rags, towels or waterproof film, as the volume of melting water can be significant, especially if the ice layer was thick. Water can flow under the baseboards or spoil the laminate, so prevention is more important here than subsequent cleaning. Make sure that the freezer doors are locked in the open position to ensure the flow of warm air.
☑️ Checklist before defrosting
Natural defrosting: a safe and recommended method
The most gentle way for the compressor, plastic parts and rubber seals is natural thawing. This method takes the most time - from 4 to 8 hours depending on the amount of ice and room temperature, but it guarantees the safety of all components of the unit. Just leave the doors open and wait for the ice to turn into water on its own. Do not try to speed up the process by opening windows wide if the room is too cold, or vice versa, directing hot air flows.
During the natural melting process, it is important to periodically check the water containers and empty them in a timely manner. If water starts to overflow, it may get into service openings or onto the floor. To speed up the process, you can place a container with warm (not hot!) water inside the chamber, but make sure that it stands stable and does not tip over. The heat from the water will gently increase the temperature inside, and the ice will begin to melt away faster.
⚠️ Attention: It is strictly forbidden to use hair dryers, heat guns or heaters to speed up defrosting. Sharp heating of the plastic can lead to its deformation, and condensation from a hair dryer getting on the electrical contacts will cause a short circuit.
After the main body of ice has melted, carefully inspect hard-to-reach places: the corners of the chamber, the space around the door seal and air exhaust channels. Often there are pieces of ice left there that need to be carefully removed with a soft spatula or gloved hand. If the ice is stuck strongly, do not use force, but rather wait a little longer or place a cloth soaked in warm water on the problem area.
Why can’t you rush the process?
Rapid defrosting using extreme temperatures (boiling water, hair dryer) causes microcracks in the plastic case and evaporator. In the future, moisture will penetrate through these cracks, causing corrosion and an unpleasant odor that is almost impossible to remove.
What you absolutely cannot do: common mistakes
The desire to quickly complete an unpleasant procedure often leads owners to fatal mistakes that turn routine maintenance into the cause of a breakdown. The most common and dangerous mistake is using sharp objects (knives, screwdrivers, chisels) to chip ice. The aluminum evaporator, hidden behind a plastic panel or in plain sight, has very thin walls, and piercing them with the edge of a knife is as easy as shelling pears.
If you heard the hiss of escaping freon after being hit with a knife, the process is irreversible at home. Refrigerant will evaporate, and air and moisture will get inside the system, which will require complex and expensive repairs with replacing the compressor or sealing the pipes. Also, do not pour boiling water directly onto the ice mass. A sudden change in temperature can cause cracks in the glass shelves (if you forgot to remove them) or deformation of the plastic interior panels.
Another mistake is not cleaning the drain hole. After the ice melts, dirt and mucus accumulated over the year can clog the water drainage channel. This will lead to the fact that during the next defrosting or during operation, water will begin to accumulate at the bottom of the chamber and flow out, spoiling the floor and creating a favorable environment for the growth of bacteria and mold.
- 🔪 Do not use knives, forks and scrapers to remove ice - this is a direct path to freon leakage.
- 🔥 Do not pour cool water boiling water on the walls of the chamber - the plastic may melt or crack.
- 💨 Do not use aggressive chemicals with chlorine or acid - they destroy plastic and rubber seals.
- 🚫 Do not turn on the refrigerator until it is completely dry - moisture on the contacts is dangerous.
Washing and disinfection of internal surfaces
After complete removal of ice, the stage of cleaning from contaminants begins. Even if the chamber appears clean visually, bacteria could have settled on the walls, causing an unpleasant odor. To wash, use a warm solution of water with the addition of baking soda, mild soap or a special refrigerator cleaner. Avoid using products with a strong odor, as plastic easily absorbs odors, which will then be transferred to the products.
Wipe all surfaces thoroughly, including the ceiling and doors. Pay special attention to the sealing rubber: mold often accumulates in its folds. Wipe the rubber with a cotton swab dipped in a vinegar solution or a special rubber cleaner to maintain its elasticity and prevent cracking. After wet cleaning, be sure to wipe all surfaces dry with a clean cloth.
Be sure to wash and dry all removed drawers and shelves before putting them back. It is better to wash plastic containers separately in a sink under running water. Make sure there are no food or residue left in the corners of the drawers, as they will become a source of odors in the freezer. After drying, reassemble the structure.
⚠️ Attention: Specifications may vary depending on the model. Always check the manufacturer's official instructions (User Manual) regarding permitted detergents, since some coatings (for example, antibacterial) require special care.
Starting the refrigerator after defrosting
The final stage is the correct start of the equipment. Make sure the inside of the cells is completely dry, all drawers and shelves are in place, and the door closes tightly. Plug in the refrigerator. If your model has a quick freezing function (Super Frost or equivalent), activate it 15-20 minutes before loading the products so that the chamber quickly reaches the desired temperature.
Do not load the products immediately. Let the refrigerator run idle for at least 1-2 hours (for No Frost models) or until the temperature in the chamber drops to nominal. This is necessary to stabilize the operation of the compressor and form the correct temperature regime. If you load warm food into a defrosted chamber, the compressor will work hard, trying to cool a large volume.
Check the operation of the thermostat and indicators. Make sure that after starting there are no extraneous noises, buzzing or knocking noises that were not there before. If everything went well, you can carefully fill the chamber with products, being careful not to block the ventilation holes (if any) and not to press the products tightly against the back wall.

Frequently asked questions (FAQ)
How often should you defrost the refrigerator Electrolux with No Frost system?
The No Frost system does not require frequent defrosting to remove ice, since it is automatic. However, maintenance, including complete shutdown, washing and disinfection, is recommended once a year. This is necessary to remove bacteria, dust from the fan and check the condition of the seals.
What to do if the refrigerator does not turn on after defrosting?
Perhaps the thermal protection relay has tripped or moisture has gotten on the contacts. Wait another 30-60 minutes for the equipment to completely dry and cool. Check that the door is tightly closed (in some models, the light inside is on and prevents starting). If the problem persists after an hour, contact the service center.
Is it possible to defrost the freezer without touching the refrigerator compartment?
In models with two independent cooling circuits (Full No Frost with two compressors), this is possible. In models with one compressor and a Full No Frost system, turning off one compartment often leads to defrosting of both, since the refrigerant circulates through a single system. In drip systems, defrosting the freezer usually requires turning off the entire unit.
Why did an unpleasant smell appear after defrosting?
Most likely, during defrosting you did not completely remove the melt water along with contaminants, and it got into hard-to-reach places or the drainage channel. The smell may also come from food debris that was in the chamber. Carry out a thorough cleaning again using a soda solution or citric acid.
Does it need to lubricate the seal after defrosting?
Yes, this is an excellent practice. Wipe the rubber seal with silicone grease or glycerin. This will prevent the rubber from drying out, maintain its elasticity and ensure a tight fit of the door, which is critical for the energy efficiency of the refrigerator refrigerator.
