Many owners of modern household appliances mistakenly believe that the system No Frost completely eliminates the need for maintenance, but this is not entirely true. Despite the absence of ice on the walls, dust, bacteria and unpleasant odors accumulate inside the housing over time, requiring intervention. Regular hygienic cleaning is necessary not only for aesthetics, but also to extend the life of the compressor and fans.
If you notice that the unit has become louder, a strange smell has appeared, or water has begun to collect at the bottom of the chamber, then it’s time for general cleaning. Ignoring these signals can lead to clogging of the drainage system and failure of expensive components. In this article we will look in detail at how to properly and safely service your model.
Before starting any work be sure to disconnect the device from the power supply, remove the plug from the socket. This is a basic safety rule that cannot be ignored since you will be working with water and electrical components. Only after complete blackout can you begin to remove products and prepare tools.
Preparation for cleaning and necessary tools
High-quality cleaning is impossible without the right equipment, which should be prepared in advance so as not to be distracted during the process. You will need soft sponges, microfiber cloth, a spray bottle of cleaning solution, and perhaps a set of screwdrivers if panels need to be removed. Do not use abrasive powders or hard brushes, as they can damage the plastic coating of the chambers.
Specialized household appliance cleaners or a weak solution of baking soda are ideal for cleaning internal surfaces. Aggressive chemistry, such as chlorine or acids, can corrode the plastic and break the seals. If you use a spray, make sure that it is safe for contact with food.
It is also worth preparing a basin with warm water and dry towels for wiping dry. In some cases, especially when cleaning hard-to-reach areas, you may need a bulb to pump out water or a syringe without a needle. All tools must be clean so as not to bring additional dirt inside the unit.
- 🧼 Soft sponges and microfiber for delicate wiping of surfaces.
- 🔧 A set of screwdrivers in case it is necessary to dismantle shelves or panels.
- 🌡️ Spray bottle with solution soda or special product for refrigerators.
- 🧽 Dry towels and a basin for collecting dirty water.
After preparing everything you need, you can move on to freeing up the internal space. It is not necessary to completely defrost the No Frost system, since the evaporator is in a closed block, but it is better to remove the products.
☑️ Preparation for cleaning
Dismantling and washing removable elements
The first stage of deep cleaning is to remove all removable parts, such as shelves, vegetable drawers and containers on the door. These elements most often come into contact with products, so they accumulate the most bacteria and contaminants. It is better to wash plastic and glass parts separately in a bathtub or large basin under running water.
Glass shelves can be soaked in warm water with the addition of dishwashing detergent to remove old stains. Plastic boxes they require more careful handling, since they can be deformed from hot water, and from aggressive agents - crack. Rinse all parts thoroughly and let them dry completely before putting them back.
⚠️ Attention: Never place cold glass shelves under hot water - a sudden temperature change may cause the glass to burst. Let them warm up to room temperature.
While the removable elements are drying, you can work on the inner walls of the chambers. Wipe them with a damp cloth, removing visible dirt, and treat them with a disinfectant spray. Pay special attention to corners and joints where mold often accumulates.
Don't forget to check the condition sealing rubber bands on the doors, as dirt is often hidden in their folds. Gently wipe the rubber with a soft cloth soaked in soapy water and check the seal. If the rubber has lost elasticity or has cracks, it should be replaced to maintain energy efficiency.
Cleaning the ventilation system and evaporator
The main difference of the system No Frost is the presence of a hidden evaporator and fan, which circulate cold air. Over time, dust and lint can build up on the fan blades and around the evaporator, reducing cooling efficiency and increasing operating noise. You can get to these components by removing the back panel in the freezer.
To access the insides, carefully unscrew the fastening screws and remove the plastic cover. Below it you will see an evaporator (radiator) and a fan. If a layer of dust is visible on the blades, it must be removed with a soft brush or vacuum cleaner at minimum power. Rotating parts should be held with your hand so as not to damage the mechanism when cleaning.
If you find an ice coat on the evaporator, this may indicate a malfunction of the defrost system, not just for cleaning needs. Under normal conditions, the evaporator should be dry or covered with a thin layer of frost, which will disappear during the defrost cycle. The presence of a large amount of ice requires diagnostics of the heating element or defrost sensor.
| Element | Cleaning frequency | Tool | Risk of contamination |
|---|---|---|---|
| Shelves and drawers | Once every 1-2 months | Sponge, water | High (bacteria) |
| Seals | Once a month | Rag, soda | Medium (mold) |
| Fan | Once every 6-12 months | Brush, vacuum cleaner | Low (dust) |
| Drainage hole | As clogged | Brush, pear | High (water) |
After cleaning the space around the evaporator, put the panel in place and secure with screws. Make sure that all the latches are in place, otherwise the seal of the chamber may be compromised.
What will happen if you do not clean the fan?
If the fan blades become covered with dust, the balancing will be disrupted, which will lead to hum and vibration. In addition, the efficiency of blowing the evaporator will decrease, and the refrigerator will begin to freeze worse, consuming more electricity.
Cleaning the drainage system
One of the most common reasons for the appearance of a puddle under the refrigerator or inside the chamber is a clogged drainage hole. Through this channel, the condensate formed during operation flows into a special container above the compressor, where it evaporates. If the hole is clogged with crumbs or mucus, water begins to accumulate at the bottom.
You can find the drainage hole on the back wall of the refrigerator, usually it is located at the bottom center. For cleaning, you can use a special brush, which is often included, or soft wire rolled into a bundle. You need to act carefully so as not to pierce the plastic drainage tube running inside the housing.
After mechanical cleaning, it is recommended to rinse the channel with warm water using a bulb or syringe without a needle. Water should flow freely without getting stuck in the groove. If the water is standing, the procedure should be repeated until the plug is completely removed.
- 💧 Use warm rinsing water to dissolve grease deposits.
- 🧶 Do not use sharp objects that could damage the drain tube.
- 🔍 Check the drain container above the compressor for debris or insects.
In some models, access to the drainage tube may be limited by design features. In this case, you should refer to the instructions or call a specialist if you are not sure of your actions.
Elimination of unpleasant odors
Even after thorough washing, an unpleasant odor emitted by plastic or ingrained food aromas may remain in the refrigerator. To neutralize it, it is not enough to simply wash the walls, you need to use absorbents. Activated carbon It is one of the best natural odor absorbers, which can be placed in containers and left inside for a day.
Ordinary black bread, cut into pieces and laid out on shelves. Dry soda in an open container or ground coffee also work great as natural deodorizers. It is better not to use chemical air fresheners, as they can impart an off-flavor to the products.
⚠️ Attention: Do not use strong fragrances immediately before loading the products. The smell can be absorbed into butter, milk and open packages.
If a new refrigerator emits a smell, this is normal for the first days of use. In this case, ventilation will help: leave the doors open for several hours in a well-ventilated area. Technical smell Plastic usually ventilates on its own within a week.
To prevent the appearance of odors in the future, store food in closed containers and promptly throw away spoiled food. Regular inspection of supplies will help maintain freshness inside the chambers.
Drying and starting after maintenance
The final stage of the procedure is thorough drying of all surfaces and elements. Humidity inside the chambers can lead to the rapid formation of new dirt and the development of microorganisms. Wipe all the walls with dry microfiber and make sure that there are no drops of water left in the recesses.
After all the parts have dried and are in place, you can connect the refrigerator to the network. Do not load the food right away - let the unit run idle for 1-2 hours until it reaches the desired temperature. This is especially important for proper operation of the system No Frost and stabilization of the temperature.
Check the operation of the fan and the absence of extraneous noise after switching on. If everything went well, you can gradually fill the chambers with products, avoiding sudden overload. Proper care guarantees long and trouble-free service of your equipment.
How often should you do general cleaning?
It is recommended to carry out general cleaning with disassembling panels and washing the fan 1-2 times a year. Superficial cleaning and washing of shelves should be done monthly or as they become dirty.
Is it possible to use a steam cleaner?
Using a steam cleaner is only possible for washing removable plastic and glass elements. Directing steam to the inner walls of the case, seals and electrical parts is strictly prohibited due to the risk of damage to the plastic and moisture getting into the wiring.
What to do if a whistling appears after cleaning?
Whistling can occur if you hit the fan blades when cleaning or poorly installed the back panel. Check to see if anything is touching the fan, and make sure that all the covers are firmly in place.
