Modern refrigeration units with the system No Frost relieved users of the need to regularly turn off equipment to thaw ice blocks. However, the absence of ice freezing on the walls of the chamber does not mean that the device is self-cleaning from dust, bacteria and odors. Many owners mistakenly believe that since ice does not form, it is necessary to wash the insides of the unit extremely rarely or not at all. This misconception can lead to the breakdown of expensive components and deterioration in the quality of food storage.
Unlike old models with a weeping evaporator, air currents circulate here, which carry not only cold, but also microparticles of dirt, mold spores and the aromas of spoiled food throughout the entire volume. Circulation system requires special attention, since the ventilation ducts are dirty channels reduces cooling efficiency and increases the load on the compressor. Proper care allows you to extend the life of your equipment and maintain hygienic safety.
In this article we will analyze in detail the algorithm of actions that will allow you to bring your refrigerator to ideal condition without resorting to lengthy defrosting. You will learn which products are safe for plastic and rubber seals, as well as how to get to hard-to-reach places where dirt most often accumulates.
Preparation for cleaning: safety and access
Before starting any manipulations with an electrical appliance, it is necessary to ensure the safety of the process. Although a complete defrost of the No Frost system is not required, a partial power outage or putting the device into maintenance mode may be necessary to access parts. First, clear all shelves and drawers of food. If you plan to wash the unit quickly, you can temporarily transfer the food into bowls with ice or into a nearby refrigerator so that they do not have time to warm up.
Next, you need to remove all removable interior elements. It is better to remove glass shelves, plastic containers, bottle holders and egg trays and wash them separately under running water using a sponge. This will allow you to properly process the surfaces without fear of damaging fragile glass or scratching the plastic with abrasive particles. Pay attention to guideson which the shelves ride - they often become a place where sticky deposits accumulate.
⚠️ Attention: Do not use hot water (above 40°C) to wash the internal chambers. A sudden temperature change can cause microcracks in the plastic or lead to deformation of the thin walls of the evaporator hidden behind the back panel.
It is also important to prepare cleaning products in advance. For a No Frost system, it is critical that moisture does not get into electrical components, so use a well-wrung out cloth. Make sure that you have access to the back wall of the refrigerator and freezer compartments, as this is where air ductsare located that require special attention.
Choice of safe cleaning products
The household chemicals market offers many specialized sprays, but not all of them are equally useful for your refrigerator. Aggressive solvents, chlorine bleaches and abrasive powders can damage the plastic coating of the cameras and rubber door seals. Over time, the plastic becomes brittle and turns yellow, and the rubber loses its elasticity, no longer fitting tightly to the body, which breaks the seal.
The safest and most effective remedy is a regular soap solution. Use laundry soap or mild dishwashing detergent diluted in warm water. A solution of baking soda (1 tablespoon per liter of water) or a weak solution of vinegar is excellent for disinfecting and removing persistent odors. These components are non-toxic and do not require thorough rinsing, which is important for food storage areas.
If you prefer ready-made chemicals, choose those labeled “for food surfaces” or “antibacterial effect.” Avoid sprays with a strong perfume scent, as plastic tends to absorb odors, and your products may later develop a strange chemical aroma. Check the composition for the presence of chlorine or ammonia - there should not be any.
Algorithm for washing the refrigerator compartment
The process of cleaning the main camera should start from top to bottom. First, wipe down the ceiling of the refrigerator, where dust and condensation often settle. Then move on to the side walls and back panel. Pay special attention to the area around ventilation holes. In No Frost systems, it is through them that cold air enters the chamber, and if these holes are clogged with dirt or pieces of food, circulation will be disrupted.
After treating the walls, thoroughly wash the bottom of the chamber. Often, it is in the recesses below that moisture and small crumbs accumulate, which become an ideal environment for the growth of bacteria. Wipe all surfaces with a clean, damp cloth to remove any remaining detergent. The door also needs to be processed on all sides, including internal pockets and shelves.
Don't forget about the rubber seal round the perimeter of the door. Mold and dirt often hide in its folds. Wipe the seal with a cotton swab dipped in a solution of vinegar or soda. This will restore its elasticity and ensure a tight fit to the door. After completing the procedure, leave the door open for 15-20 minutes to ventilate and dry.

Features of cleaning the No Frost freezer
The freezer compartment in systems with “no-frost” technology requires a more delicate approach, despite the absence of a thick layer of ice. The important thing here is not to damage the thin layer of frost on the evaporator, which is located behind the plastic back wall. If you notice that water or ice chips have accumulated at the bottom of your freezer, this is a sign that the drainage hole may be clogged.
Use a minimal amount of water to clean your freezer. It is better to use the spray method: spray the cleaner onto a rag and then wipe the surfaces. Do not pour water directly into the bottom of the chamber, as it may instantly freeze in the drainage tube, creating an ice plug that will be time-consuming and difficult to remove. Wash all removable drawers and baskets separately and dry before installing them back.
⚠️ Attention: It is strictly forbidden to use a knife, ice pick or other sharp objects to pick off ice or frost in the freezer. One careless movement can puncture the evaporator channels, and the refrigerator will fail, requiring expensive repairs.
Inspect the ventilation grilles on the back wall of the freezer. If they are clogged with “fluffy” dust or products, carefully remove the dirt with a dry soft brush or vacuum cleaner at minimum power. The cleanliness of these grates directly affects the rate of freezing of food and the energy consumption of the device.
What to do if an ice plug has formed in the freezer?
If you notice that the water does not go into the drainage and freezes at the bottom, do not try to pick out the ice. Try carefully pouring some warm water from a syringe without a needle into the drainage hole (at the bottom or behind the back wall, if there is access). This will help melt the cork. If this does not help, you will need to call a technician to blow out the drainage.
Cleaning the ventilation system and hidden areas
The main difference between caring for a No Frost refrigerator is the need to keep the air circulation system clean. The air in such models is constantly forced through the evaporator and filter (if provided by the model), and then distributed among the chambers. Over time, grease and dust can accumulate on the fan blades and channels, which leads to an unpleasant odor and noise during operation.
You can usually get to the fan by removing the back plastic panel in the freezer (you need to unscrew the screws). If you decide to do this procedure, be sure to unplug the refrigerator. Gently wipe the fan blades with a dry or slightly damp cloth. Do not wet the electrical part of the motor. Also check the condition thermal insulation and wires for damage.
Some modern models have carbon filters for deodorization. They must be checked and replaced periodically according to the manufacturer's instructions (usually every 6-12 months). If the filter is dirty, it stops purifying the air and becomes a source of odor itself. You can replace the filter yourself by finding its location in the technical documentation.

| Walls and ceiling of the chamber | Once every 1-2 months | Specialized spray, vinegar | Soft cloth, spray bottle |
| Rubber seal | Once a month | Soda or vinegar solution | Cotton swab, soft brush |
| Ventilation holes | Once every 6 months | Dry cleaning, vacuum cleaner | Soft brush, vacuum cleaner |
Drying and the final stage
After wet cleaning, it is critical to let all surfaces dry completely. Residual moisture in a No Frost system can quickly turn into a crust of ice when the compressor is turned on, especially in the freezer. Leave the doors open for at least 30-40 minutes. To speed up the process, you can wipe the surfaces with dry microfiber, which perfectly absorbs moisture without lint.
Before loading the products back, make sure that the chamber is at room temperature and there is no smell of detergents. Products should be placed so that they do not block the cold air outlets. This will ensure uniform cooling and prevent food spoilage.
Plug in the refrigerator and let it run idle for about 1-2 hours until it reaches the required temperature. Only after this can the chambers be filled with products. Regular maintenance, even without completely defrosting, will keep your unit operating efficiently for many years.
⚠️ Attention: Specifications and location of elements (such as drain hole or filter) may vary depending on the model and manufacturer. Always check the official instructions for your device before disassembling the panels.
How to remove the smell after cleaning?
If the smell remains after washing, place an open container with activated carbon, ground coffee or lemon zest on the shelf. These natural absorbents quickly neutralize foreign odors.
Frequently asked questions (FAQ)
Is it possible to wash a refrigerator without unplugging it?
It is highly not recommended. Water and electricity are a dangerous combination. Even with careful operation, splashes can get on the contacts or control board, causing a short circuit. In addition, a running fan may spray water around the chamber. Always unplug the appliance from the outlet before washing.
How often should you wash a No Frost refrigerator?
It is recommended to carry out general cleaning with washing shelves and walls once every 2-3 months. However, spills and crumbs should be wiped up immediately. If you store products with a strong odor (fish, smoked meats), the frequency of cleaning should be increased to once a month.
What cannot be used to wash the inside of the refrigerator?
It is prohibited to use gasoline, acetone, chlorine-containing bleaches, abrasive powders (such as Pemolux) and hard metal sponges. These substances destroy the structure of the plastic, make it cloudy and brittle, and can also be toxic to products.
Why did an unpleasant odor appear after washing?
This may mean that dirt has gotten into hard-to-reach places, for example, in the drain hole or behind the evaporator panel. The smell can also come from a forgotten piece of product that fell behind a drawer. Try rinsing the drainage hole with warm water and baking soda.
Do you need to remove the back panel for routine cleaning?
For scheduled monthly cleaning, you do not need to remove the back panel. Simply wipe the visible ventilation holes with a soft brush. Dismantling the panel is required only for deep cleaning of the ventilation system or troubleshooting, and it is better to do this if you have skills in handling equipment.
