Owners of built-in appliances often face a dilemma: when the time comes for scheduled defrosting, what to do to avoid damaging the furniture set? Unlike free-standing models, integrated units are tightly enclosed in a niche made of chipboard or MDF, which creates a risk of swelling of the material when moisture enters. Ignoring the procedure for removing ice leads to a decrease in the efficiency of the compressor and an increase in energy consumption, so the issue requires a competent and timely solution.
The process of removing ice crust requires preparation and adherence to certain time intervals. Modern systems Automatic defrosting greatly simplifies life, but even they do not guarantee a complete absence of ice if the door is frequently opened or malfunctions seal. In this article, we will analyze an algorithm of actions that will help you safely carry out the procedure and preserve the appearance of your kitchen.
Preparing for the procedure of defrosting built-in appliances
The first step is to free the internal space from products. Built-in refrigerator has a smaller usable volume due to the walls of the furniture box, so it is better to distribute the products in advance into containers for quick transfer. If it is a cold season outside, the contents can be taken out to the balcony, having previously been protected from direct sunlight and precipitation.
A critically important step is organizing the drainage of melt water. Since appliances are built into furniture, a standard drain is often missing or inaccessible. You will need flat containers with low sides that can be placed under the drainage hole, and a sufficient number of absorbent rags or paper towels. Drainage system Must be cleaned before starting the process so that water does not overflow.
⚠️ Attention: It is strictly forbidden to use sharp objects to chipping ice in built-in models. Damage to the evaporator hidden behind the plastic panel will lead to a refrigerant leak and costly repairs, which will require dismantling the entire furniture set.Prepare a place for temporary storage of food in advance. This could be a nearby refrigerator, a thermal box, or just a cool room. Fast movement of products minimizes the risk of their spoilage while Temperature conditions the temperature inside the chamber is increased
Disconnection of power and dismantling work
After preparation, it is necessary to de-energize the device. For built-in models, this may not be as easy as for conventional ones, since the outlet is often located in a hard-to-reach place inside the cabinet or behind the baseboard. Find the connection point and remove the plug from the network. If access to the outlet is blocked, it is allowed to turn off the machine in the electrical panel, but only the one responsible for the kitchen area.
In some cases, for high-quality defrosting, partial dismantling of the facades or removal of decorative panels is required. It depends on the design of your furniture. If there is a gap of less than 5 cm between the walls of the niche and the body of the refrigerator, air access will be difficult and the process will take longer. In such a situation, it may be necessary to loosen the fastenings in order to move the unit forward a little.
☑️ Preparing for defrosting
Done: 0 / 5Do not forget to remove all removable elements: shelves, drawers, egg trays and bottle holders. It is better to wash them separately with warm water and a mild detergent while the main process is in progress. Plastic parts become brittle at low temperatures, so avoid sudden temperature changes when washing.
Natural defrosting versus accelerated methods
There are two main approaches to removing ice: natural and forced. The natural method is to wait for the ice to melt on its own at room temperature. This is the safest option for compressor and internal plastic elements, but it takes time - from 10 to 24 hours depending on the thickness of the ice.
Accelerated methods are used when time is limited. However, they carry risks. Using a hairdryer is permissible only at a minimum temperature and with a constant flow of air. Directing hot air to one point is prohibited, as this can cause deformation of the plastic or damage the door seals.
Many users wonder about the advisability of using hot water. You can place containers of boiling water inside the chamber, but with caution. Steam may damage the lacquer finish of the shelves or cause the plastic to become cloudy. It is better to use warm water in a spray bottle to spray the walls, which will speed up the melting without aggressive effects.
Why can’t you use a knife?
Using a knife or screwdriver to pick at ice is the most common reason for refrigerator failures. The thin evaporator tube is located just behind the plastic. One wrong puncture will result in gas hissing and a complete loss of cooling capacity. Repairing such a system is often not economically feasible.
When choosing a method, evaluate the condition of the seals. If the elastic has not been washed for a long time and has lost its elasticity, the hot air from the hair dryer can completely ruin it. In this case, it is preferable natural thawing.
Features of defrosting the No Frost system
Owners of equipment with the system No Frost are often surprised to find ice inside the chambers. Theoretically, such models do not require manual defrosting, as they are equipped with defrosting heating elements and timers that automatically remove moisture. However, if ice appears, this is a signal of a malfunction or improper operation.
The reasons for the formation of ice in No Frost may be the following:
- ❄️ The drainage hole is clogged, and the condensate does not have time to evaporate.
- ❄️ The defrost sensor or heating element is faulty.
- ❄️ The door does not fit tightly due to distortion or contamination of the seal.
- ❄️ Products that have not cooled down to room temperature are placed in the chamber.
If you are faced with such a situation, simple defrosting may not solve problem permanently. After thawing and switching on, the equipment may begin to become covered in ice again after a few days. In this case, diagnostics is required air circulation system.
System type Defrost frequency Process duration Risk for furniture Drip 2 times a year 12-24 hours High (lots of water) No Frost Only in case of breakdown 4-8 hours Average Combined once a year 10-15 hours Average It is important to understand that No Frost is characterized by the formation of a “snow coat” on the back wall only in case of a program failure. If ice appears, be sure to check the drainage in the freezer, which is often hidden behind a decorative panel.
Protecting furniture and floors from moisture
The main enemy when defrosting built-in appliances is water that gets on the floor or in the joints of the furniture frame. Laminated chipboard swells instantly, and it is almost impossible to restore its original appearance. To avoid disaster, use absorbent materials.
Put several layers of old towels or a special absorbent diaper (can be purchased at a pet store) on the floor in front of the refrigerator. If the design allows, place rags in the gap between the bottom of the refrigerator and the bottom of the niche. The water will flow exactly there.
⚠️ Attention: If water does get on the end of the furniture board, immediately dry this area with a hairdryer (on a cold setting) and treat moisture-proofing compound or furniture wax. Delay will lead to delamination of the particle board.It is also worth checking the condition of the rear wall of the niche. Often condensation accumulates there and flows down. Wipe all accessible surfaces with a dry cloth before placing the equipment in place. Ventilation gaps Must be completely dry.
Completing the process and first start
When all the ice has melted and the water removed, you must thoroughly wipe the internal surfaces with a dry, clean cloth. Do not rush to turn on the device right away. Let it stand turned off for another 30-60 minutes so that any remaining moisture evaporates and the temperature of the internal components becomes equal to room temperature.
Install all shelves and drawers in their places. Make sure the drainage hole is clear. Now you can connect the device to the network. Once turned on, do not load products immediately. Let the refrigerator run idle for 2-3 hours so that it reaches operating temperature.
📊 How often do you defrost the refrigerator?Once every six monthsOnly when the ice freezesNever (No Frost)Once a yearCheck the operation of the thermostat. If after defrosting the refrigerator does not work correctly (for example, it does not turn off or does not freeze enough), the electronics may have been damaged during the defrosting process or the tightness of the circuit has been broken. In such a situation, it is better to contact specialists.
Frequent errors when servicing built-in models
One of the common mistakes is ignoring the manufacturer’s instructions. Each brand (Bosch, Liebherr, Electrolux) may have its own nuances in the location of drainage or fastening of facades. Trying to act “by eye” often leads to broken latches or stripped threads.
Another mistake is the use of aggressive chemicals to remove ice or wash. Glass sprays or abrasive powders can damage the interior plastic coating, making it porous. Bacteria will then clog into the microcracks, which will lead to the appearance of an unpleasant odor.
You should also not neglect prevention. Even if there is no visible ice, once every six months it is worth checking the condition of the seals and the cleanliness of the ventilation holes. Regular care extends the life of the equipment and maintains its energy efficiency.
Questions and answers (FAQ)
Is it possible to defrost a built-in refrigerator without removing it from the niche?
Yes, in most cases complete dismantling is not required. However, it is necessary to provide access to the bottom of the unit to install containers with water and check whether the furniture does not interfere with the free opening of the doors by 90 degrees or more.
How long does it take to defrost a built-in model?
On average, the process takes from 10 to 24 hours. The time depends on the thickness of the ice layer, the room temperature and the chosen method (natural or accelerated). Do not try to sharply reduce the time using boiling water, this can be dangerous.
What to do if after defrosting the refrigerator does not freeze?
If after turning on for 3-4 hours the temperature does not decrease, there may be a malfunction of the electronics or, in the worst case, a freon leak due to mechanical damage. Try turning off the power completely for 15 minutes and turning it on again. If the problem is not solved, call a specialist.
Do you need to wash the refrigerator after defrosting?
Required. Along with the melting ice, dust and possible contaminants flow onto the floor. Wipe the inner walls with a soda solution or a special household appliance product, and then wipe dry with a clean cloth.
