Regular maintenance of household appliances is the key to its long and uninterrupted service. Refrigerators of the brand Don, widely known for their reliability and simplicity of design, also require periodic cleaning of ice. Many owners mistakenly believe that modern No Frost systems completely eliminate the need for defrosting, however, even in such units, the hidden type evaporator needs attention over time. Ignoring this procedure can lead to a decrease in cooling efficiency and an increase in energy consumption.
The ice removal process cannot be rushed and requires compliance with certain safety rules. Incorrect actions, such as using sharp objects or boiling water, can cause irreparable damage to the heat exchanger. In this article we will analyze in detail all the stages of preparation, the process itself and the subsequent start-up of your refrigerator so that it works again with maximum efficiency.
Preparing equipment for defrosting
The first and most important step is complete turning off the power supply. Unplug the cord from the outlet to eliminate any risk of short circuit or electric shock when working with water. If access to the outlet is difficult due to the tight installation of equipment, it is recommended to provide an extension cord in advance or temporarily move the unit away, being careful.
Next, you need to empty the cameras of their contents. All food should be transferred to another cool place, for example, in ice bowls or on a balcony (in winter) to prevent spoilage. It is better to remove the shelves and drawers immediately - this will not only make access to the walls easier, but you will also be able to wash them separately in the bathtub or basin.
⚠️ Attention: Never leave the refrigerator doors wide open for a long time unless necessary, if the room has high humidity. This can lead to condensation on internal mechanisms and wiring, which is undesirable for electronics.
Prepare a place to collect melt water. Cover the floor around the refrigerator with absorbent rags or towels. For models with a bottom-mounted freezer, it is often necessary to place a flat tray, since water can flow out through the drainage hole or simply flow down the body.
Natural defrosting versus accelerated methods
There are two main approaches to removing ice crust: natural thawing and forced acceleration of the process. The natural method is the most gentle for evaporator and internal plastic elements. It takes longer - from 3 to 10 hours depending on the thickness of the ice, but guarantees the absence of thermal shock to the materials.
Accelerated methods are used when time is limited. However, it is important to observe moderation here. The use of hair dryers is permissible only at a minimum temperature and with a constant flow of air. It is strictly forbidden to direct hot air to one point for a long time, as this can deform the plastic or damage the seals.
- ❄️ Natural method: safe, long-lasting, does not require control.
- 🌬️ Hair dryer: fast, but there is a risk of overheating the plastic.
- 💧 Warm water: effective, but requires care when collecting moisture.
- 🧊 Scraper: dangerous, high risk of tube breakdown.
⚠️ Attention: Using boiling water to speed up the melting of ice can lead to cracks on plastic shelves and deformation of the internal coating of the chambers due to a sharp change temperatures.
Why can’t you use a knife?
The use of a knife or other sharp objects to chip ice is strictly prohibited. In Don refrigerators, as in most models, the evaporator tubes are located very close to the inner wall. One careless movement will lead to a breakdown and instant release of refrigerant. Repair in this case will not be economically feasible.
Step-by-step instructions for defrosting the Don refrigerator
After you have turned off the appliance and prepared the place, the main stage begins. Leave the doors open. If your model has a special gutter for draining melt water, make sure it is not clogged with food debris. The water should flow freely into the prepared container.
During the melting process, you can carefully remove large pieces of ice with your hands (wearing gloves), but without using force. If there is a lot of ice, you can use the “warm compress” method: soak a towel in warm (not hot!) water and place it on the ice crust. This will speed up the process without the risk of damage.
Be sure to wait until the internal surfaces are completely dry. Residual moisture in hard-to-reach areas can cause mold or unpleasant odors in the future. Wipe all corners and joints with a dry cloth.
☑️ Checklist for proper defrosting
Care for seals and internal shelves
While the chambers are empty and dry, it’s time to pay attention to cleanliness. Rubber seal on the doors is a critical element that ensures tightness. Over time, dirt, grease and germs accumulate on it, which leads to loss of elasticity and fit.
Wash the seal with a soft sponge using a mild soap solution or a special rubber product. After washing, be sure to wipe it dry. To extend the life of the rubber, you can treat it with silicone grease or glycerin, which will prevent drying out and cracking.
Removable shelves and drawers also require careful washing. Plastic easily absorbs odors, so using baking soda or a vinegar solution will help neutralize extraneous odors. Do not use abrasive powders, which can leave micro-scratches where bacteria will subsequently multiply.
Mistakes made during defrosting
The most common and fatal mistake is trying to pick out the ice with a knife, screwdriver or snow shovel. In Don models, the cooling system is often made in the form of a foamed evaporator or hidden channels. Damage to such a system leads to freon leakage and moisture entering the circuit, which requires complex evacuation and refilling by a specialist.
The second mistake is turning on the device immediately after the ice has melted. The compressor should "rest". If you have been defrosting your refrigerator for a long time, the oil in the compressor may have thickened or shifted. A sharp start can lead to water hammer or jamming of the mechanism.
| Error | Consequences | How to do it correctly |
|---|---|---|
| Chipping ice with a knife | Puncture of tubes, leakage freon | Wait for natural melting |
| Wash with boiling water | Deformation of plastic, cracks | Use warm water (30-40°C) |
| Switch on without drying | Short circuit, corrosion | Wipe all surfaces thoroughly |
| Ignoring drainage | Clogged, water on the floor | Clean the hole brush |
⚠️ Attention: If you accidentally damage the tube and hear hissing (gas escaping), stop work immediately, ventilate the room and call a technician. You cannot refuel the refrigerator yourself.
Starting the refrigerator after defrosting
When the unit is completely clean and dry, you can begin assembly. Replace all shelves, drawers and containers. Make sure they are securely fastened. Now you can turn on the refrigerator.
After turning on, do not rush to load the food. Let the equipment run idle for at least 1-2 hours (for models with No Frost the time may be less, about 30-40 minutes). This is necessary to stabilize the temperature and allow the compressor to enter the operating cycle.
Check the thermostat operation. Make sure that the temperature in the chambers begins to decrease and the compressor switches off periodically. If all parameters are normal, you can carefully add food, trying not to overload the chambers right away.
How long does it take to completely defrost a Don refrigerator?
The time depends on the thickness of the ice crust and the temperature in the room. On average, the process takes from 3 to 8 hours. If there is not much ice, 2 hours may be enough. It is not recommended to speed up the process with a hairdryer more than once every few years.
Is it necessary to defrost a refrigerator with the No Frost system?
Technically, the No Frost system prevents the formation of visible ice in the chambers. However, once every 1-2 years it is recommended to carry out preventive defrosting and washing to remove bacteria and check the operation of the drainage system, which may become clogged.
What to do if after defrosting the refrigerator does not freeze?
Perhaps the compressor has gone into protection or damage has occurred due to careless cleaning. Wait 2-3 hours. If the cold does not appear, and the compressor works constantly or does not turn on at all, diagnostics by a technician is required.
