Modern refrigeration units of the Danish brand Vestfrost are deservedly popular due to their reliability and thoughtful design, but even the most advanced models require regular maintenance. Defrosting the freezer is a mandatory procedure that helps maintain the energy efficiency of the compressor and extends the life of the entire cooling system. Ignoring this need can lead to the formation of a thick ice crust, which not only reduces the useful volume of the chamber, but also creates excess load on the engine.
Many owners mistakenly believe that the No Frost or Low Frostsystems that many are equipped with models Vestfrostare completely free from manual intervention. In fact, although the evaporator in such units is protected from freezing, the inner surface of the walls and door seals still require periodic cleaning of condensation and microscopic ice particles. A correctly carried out procedure will take no more than a couple of hours, but will ensure ideal hygiene and a fresh smell inside your refrigerator.
In this article we will analyze in detail the algorithm of actions for various types of refrigerators, point out common mistakes and answer questions that users often have when servicing equipment. It is critically important not to use sharp objects to chip ice, since damage to the evaporator will lead to costly repairs and replacement of the refrigerant. Following proven instructions will allow you to safely and effectively perform all the necessary manipulations.
Preparation for the defrosting process
Before starting any work, you need to properly plan your actions to minimize inconvenience and avoid food damage. Full defrosting implies a power outage, so all perishable supplies should be moved to another cold place in advance or used insulated containers with ice. If it is winter outside, you can take the food out to the balcony, but make sure that the temperature is not extremely low for some types of vegetables and fruits.
You will need to prepare certain equipment that will make cleaning easier and protect the floor covering from water. Cover the floor around the refrigerator Vestfrost absorbent mats, old towels or thick rags. Also, find a container in advance to collect melt water if the design of your model does not provide a built-in drainage channel on the outside of the case.
☑️ Preparing for defrosting
Pay attention to the condition of the door seals before starting washing. If the rubber bands are heavily soiled or sticky, they will need to be treated separately after the main ice has melted. The cleanliness of the seals directly affects the tightness of the chamber and the absence of ice freezing in the future.
Step-by-step instructions for defrosting
The process of getting rid of ice must take place in strict sequence to avoid stress for the compressor and electrical control system. First, find the temperature regulator, which in models Vestfrost is usually located on the top panel or inside the chamber, and move it to position OFF or 0. Only then can you unplug the power cord from the outlet.
Leave the freezer and refrigerator doors open. Natural melting of ice is the safest method that does not require the use of aggressive chemicals or mechanical impact. Depending on the thickness of the ice layer, this process can take from 3 to 24 hours. It is not recommended to accelerate it artificially, since a sharp temperature change is harmful to plastic and metal elements.
If you are the owner of a model with a system No Frost, then full defrosting with power off is rarely required, usually once a year for hygienic washing. In models with a drip system or static cooling, the procedure is carried out as ice forms more than 5-7 millimeters thick.
⚠️ Attention: It is strictly forbidden to use hair dryers, fan heaters or hot water to accelerate the melting of ice. The flow of hot air can deform plastic shelves and damage the fragile evaporator tubes hidden behind the back wall.
Features of defrosting systems No Frost and Low Frost
Technology No Frost (translated as “no frost”) involves automatic removal of moisture, but this does not mean a complete absence of the need for maintenance. In such refrigerators Vestfrost moisture is removed from the food, circulates in the form of cold air and settles on a hidden evaporator, from where it is periodically removed by a heating element. Despite this, a thin coat of snow may form inside the chamber due to frequent opening of doors or storage of uncovered liquid food.
For models with marking Low Frost less ice formation is typical compared to classical systems, but periodic defrosting is still necessary. The main advantage of such systems is the absence of protruding heating elements and smoother internal walls, which greatly simplifies the cleaning process. You don’t have to wait a day, usually 2-4 hours are enough for complete removal of residual frost.
Why does ice still appear in No Frost?
Ice in No Frost systems appears due to a broken door seal, a clogged drain hole or a malfunction of the defrost sensor. Also, the reason may be placing hot foods in the chamber or storing liquids without a lid.
When cleaning the ventilation ducts in the freezer Vestfrost be extremely careful. Do not push rags or cotton swabs too far into the holes, as this may damage the fan blades or dislodge the ducts. Light blowing with a dry soft brush will be the safest solution.
Cleaning and care after defrosting
After all the ice has melted and the water has been removed, the stage of thorough cleaning of the internal surfaces begins. To wash plastic and glass shelves, it is best to use a weak solution of baking soda or specialized household appliance products that do not contain abrasive particles. Aggressive chemicals can leave scratches or change the color of the internal panels.
Pay special attention to the drainage hole, which is often located on the back wall or in the bottom corner of the camera. If it is clogged with crumbs or mold, the moisture will not escape, which will lead to the formation of puddles and rapid re-freezing of ice. You can clean the channel using a special flexible brush or soft wire wrapped in fabric.
| Cleaning element | Recommended product | Frequency of treatment | Tool |
|---|---|---|---|
| Internal walls | Soda solution (1 tbsp per 1 liter of water) | At each defrost | Soft sponge |
| Door seals | Warm soapy water | Once every 2-3 months | Cotton pad |
| Shelves and drawers | Dishwashing liquid | With each defrost | Sponge + water |
| Outer body | Stainless steel polish | Once a week | Microfiber |
After wet cleaning, be sure to wipe all surfaces dry with a clean cloth. Remaining moisture may cause an unpleasant odor or bacterial growth. Keep the refrigerator doors open for another 15-20 minutes after cleaning so that the dampness is completely evaporated.
Common mistakes when defrosting
One of the most common mistakes is trying to mechanically pick off the ice with a knife, screwdriver or other sharp object. The inner wall of the freezer Vestfrost hides thin tubes with refrigerant underneath. One awkward movement can lead to a puncture, freon leak and compressor failure, which often makes repairs economically impractical.
Another mistake is turning on the refrigerator immediately after washing, without allowing it to dry. Moisture on electrical contacts or light bulb sockets can cause a short circuit. Also, do not load the chamber with products immediately: let the unit run idle for 1-2 hours so that it reaches operating temperature.
Do not ignore the smell after defrosting. If an unpleasant odor remains after washing, this may indicate mold in hidden cavities or drainage. In this case, it is recommended to wipe the surfaces with a solution of vinegar or citric acid, which perfectly neutralize odors.
Starting the refrigerator after maintenance
When the chamber is completely clean and dry, you can start starting the equipment. Close the doors and plug in the power cord. Set the temperature control to the position recommended by the manufacturer, usually this value -18°C for the freezer compartment and +4°C for the refrigerator compartment.
Do not rush to load food. The compressor Vestfrost will need time to cool the empty walls and air inside the chambers to the specified parameters. Depending on the volume of the freezer and the room temperature, this process can take from 2 to 6 hours. Loading warm food into a cold chamber will force the compressor to work at its limit.
After the first cooling cycle, check the operation of the system. The engine should operate silently or with an even low hum, without knocking or vibration. If all the parameters are normal, you can gradually fill the freezer with food, trying not to block the ventilation holes.
What to do if the refrigerator does not freeze after defrosting?
If more than 6 hours have passed since it was turned on and the temperature does not drop, check the tightness of the door and the operation of the fan. Also make sure the thermostat is set to the correct position. If the problem persists, there may be a power surge or damage to the control system during defrosting, which requires calling a technician.
Is it possible to defrost a refrigerator on the balcony in winter?
It is not recommended to take the refrigerator out into the cold to defrost. Sudden temperature changes can lead to cracking of the plastic and damage to the paintwork. In addition, the oil in the compressor thickens in extreme cold, and starting the equipment immediately after entering the heat can be dangerous for the engine.
How often do you need to defrost Vestfrost with No Frost?
Models with the No Frost system do not require regular defrosting to remove ice, as they do this automatically. However, once every 6-12 months it is recommended to completely wash and disinfect the chambers, unplugging them to maintain hygiene standards and freshness.
Why did an unpleasant odor appear after defrosting?
An unpleasant odor often occurs due to moisture residues in hard-to-reach places where bacteria have begun to multiply, or due to the fact that the drainage hole it was clogged and the water stagnated. Thorough drying and treating the surfaces with a solution of soda or vinegar will help eliminate the problem.
