An ice “coat” in the freezer is a problem that every third owner of a two-chamber refrigerator faces. At first glance, harmless freezing of the walls can lead to serious damage: from increased energy consumption to compressor failure. In this article we will analyze 7 key reasonswhy the freezer freezes - from banal operating errors to hidden technical faults.
The peculiarity of two-chamber models (as opposed to single-chamber ones) is that the freezer and refrigeration compartments work in one cooling system, but with different temperatures. When the balance is upset, moisture from the air condenses and freezes on the walls of the freezer. It is important to understand: if ice appears regularly (more than once every 2-3 months), this is a signal of a problem, and not normal operation of the equipment.
We will not advise “just defrosting the refrigerator” - instead you receive step-by-step diagnostics with photos of signs of each malfunctiona table of symptoms and solutions (including those that you can do yourself). And at the end of the article - an FAQ with answers to the most frequently asked questions about specific models Atlant, Samsung, Indesit and LG.
1. Door seal failure: how to check and fix
The most common cause of ice is loose sealing rubber in the freezer compartment. Even a micro gap of 1-2 mm leads to the entry of warm air, which condenses and freezes. In two-chamber refrigerators, this is especially critical, since the freezer usually opens more often than the refrigerator compartment.
How to diagnose:
- 🔍 Visual inspection: shine a flashlight along the seal with the door closed. If light is visible, the seal is broken.
- 📄 Test with paper: clamp a sheet of paper between the door and the body. If it falls out or is easily pulled out, the seal is worn out.
- ❄️ Localization of ice: if ice forms only around the perimeter of the door, the problem is definitely in the rubber band.
Solutions:
- 🛠️ Cleaning and lubrication: wipe the seal with a soda solution (1 tablespoon per 1 liter of water), then apply silicone grease (for example, WD-40 Specialist).
- 🔥 Restoring the shape: if the rubber is deformed, immerse it in hot water (60-70°C) for 5-10 minutes, then apply the correct shape and fix with tape until it cools.
- 💰 Replacing the seal: for models Samsung RL38* or Atlant MXM-180 original elastic bands cost 1,200–2,500 ₽. Selection according to the model is required!
⚠️ Attention: Do not use vegetable oil or petroleum jelly for lubrication - they attract dust and accelerate wear of the seal.
2. Malfunction of the No Frost defrosting system: symptoms and repair
In refrigerators with a system No Frost (for example, LG GA-B489 or Bosch KGN39XL40) is often responsible for freezing of the freezer defrosting failure. In normal mode, the fan distributes the cold evenly, and the heating element (heating element) is periodically turned on to melt the ice. If the heating element or defrosting timer fails, ice accumulates on the evaporator and walls.
Symptoms of malfunction No Frost:
- ❄️ Ice forms on the back wall in the freezer (the evaporator is located there).
- ⚙️ The refrigerator runs almost non-stop, but does not cool properly.
- 🔊 Appears uncharacteristic noise (humming or crackling) - this may be a faulty fan.
Diagnostics and repair:
- Turn off the refrigerator and defrost it for 12-24 hours. If ice appears again within 12-24 hours after turning it on. 1-2 weeks - a problem in the defrosting system.
- Check the defrosting heating element with a multimeter (resistance should be 200–500 Ohms). If it shows “0” or “1”, the part has burned out.
- Inspect defrost timer (usually located at the bottom of the refrigerator behind the panel). When turning the handle, a click should be heard.
| Faulty element | Replacement cost (₽) | Difficulty of repair |
|---|---|---|
| Heating element defrost | 1 500–3 000 | Medium (requires a soldering iron) |
| Defrost timer | 2 000–4 500 | Simple (module replacement) |
| Defrost sensor | 1 800–3 500 | Complex (needs board diagnostics) |
| Fan | 2 500–5 000 | Simple (if available) |
⚠️ Attention: In refrigerators Samsung with system Twin Cooling Plus (two independent cooling systems) there is a malfunction thawing in the freezer does not affect the refrigeration compartment. If there is ice only in the freezer, the problem is local.
3. Clogged drainage hole: step-by-step cleaning
The drainage hole in the freezer is responsible for draining condensate. If it becomes clogged with crumbs, ice or mold, the water stagnates. freezes, forming ice on the bottom of the chamber. This problem is typical for models with a drip defrosting system (for example, Indesit DF 4180 or Beko CNK 335120).
How to understand that the drainage is clogged:
- 💧 Water accumulates at the bottom of the freezer, which then freezes.
- 🧊 Ice forms only in the lower part chambers.
- 🤢 An unpleasant odor appears (due to decomposing organic particles in the clog).
Instructions for cleaning:
Turn off the refrigerator and take out all the food|Find the drainage hole (usually in the center of the back wall)|Rinse the hole with warm water and soda (1 tsp per 200 ml)|Use a cotton swab or a special brush to remove dirt|Blow out the hole with a rubber blower or vacuum cleaner (in blowing mode)|Fill in 50 ml of hot water (60-70°C) to check the permeability-->
If mechanical cleaning does not help, the blockage may be deeper - in the drainage tube. In this case, you will need to disassemble the back panel of the freezer (it is better to entrust this to a specialist). temperature or operating mode once every 3 months.
4. Incorrect temperature or operating mode
Many users mistakenly believe that the lower the temperature in the freezer, the better. However, excessive cooling (below -24°C) leads to intense ice formation, especially if:
- 🌡️ B the refrigerator is switched on
Super FreezeorFast Freeze(accelerated freezing). - 📉 The ambient temperature is below +16°C (for example, the refrigerator is in a cold room).
- 🔄 The door opens frequently (more than 10 times per day).
Optimal settings for two-chamber refrigerators:
- 🥶 Freezer compartment: -18°C (for long-term storage) or -20°C (if you store meat/fish for more than 3 months).
- ❄️ Refrigerator compartment: +4°C (zone freshness) up to +6°C (door shelves).
How to set the temperature correctly:
- In models with electronic control (for example, LG GB-B409SLQZ), set the mode
EcoorOptimal. - In mechanical refrigerators (for example, Biryusa 145) turn the knob to the division between
3and4. - Use external thermometer to check (put it between products for 12 hours).
5. Freon leak: how to recognize and what to do
One of the most serious causes of freezing is refrigerant (freon) leak. It occurs due to microcracks in the evaporator tubes or after unqualified repairs. In this case, the freezer can either become covered with ice (if the leak is small), or stop freezing (if freon is completely lost).
Signs of a freon leak:
- ❄️ Ice forms in an uneven layer, often on one side of the freezer.
- ⏳ The refrigerator works almost non-stop, but does not cool properly.
- 🔧 On the back wall of the refrigerator you can see oil stains (freon mixed with oil compressor).
What to do:
- Turn off the refrigerator and do not turn it on —working without freon leads to overheating of the compressor.
- Call a technician for leak diagnostics (cost from 1,500 ₽) and refueling freon (from 3,000 ₽).
- If there is a crack in the evaporator, you will need it replacement (from 5,000 ₽).
⚠️ Attention: Refilling freon yourself is dangerous! The refrigerant is toxic, and incorrect dosage can damage the compressor. Contact only certified service centers.
How to check the compressor for operation?
If the refrigerator does not freeze, but the compressor is humming, put your hand on its body (it is located in the lower part at the back). Normally, the compressor should be warm, but not hot. If it is cold , there may be a freon leak or a malfunction of the start relay. If scalding hot - the compressor is worn out and requires replacement.
6. Malfunction of the thermostat or electronic control unit
The thermostat (in mechanical refrigerators) or the electronic unit (in modern models) is responsible for maintaining the set temperature. If they fail, the compressor either works without stopping (leading to freezing) or turns off too early (then the food is defrosted). but in fact -25°C).
Symptoms of malfunction:
- 📊 Freezer temperature does not correspond to the settings (for example, it is set to -18°C, but in fact -25°C).
- 🔄 Refrigerator turns on and off cyclically with an interval of less than 10 minutes.
- 💥 On the display appears errors (for example,
E1orFFin models Samsung).
Diagnostics and repair:
- 🔧 Mechanical thermostat: Check with a multimeter (if at room temperature the resistance should be 0 Ohm, when cooling - infinity). Replacement costs 1,200–2,500 ₽.
- 📱 Electronic unit: Diagnostics is required at a service center (cost from 3,000 ₽) In 30% of cases it helps. data-i="217">, in the rest - replacement of the board. flashing, in the rest - board replacement.
- 🔄 Reset settings: In models LG press the buttons
Freezer+Fridgefor 10 seconds to reset.
7. Operating errors: what are you doing wrong
Sometimes the cause of ice lies not in breakdowns, but in misuse the refrigerator Here are the most common mistakes:
Checklist “What not to do”:
- 🚫 Place hot foods in the freezer - the steam from them condenses and freezes.
- 🚫 Store liquids in open containers - the moisture evaporates and settles on the walls.
- 🚫 Overload the freezer —air circulation is disrupted and ice forms unevenly.
- 🚫 Use unsealed bags —foods “dry out,” increasing the humidity in chamber.
- 🚫 Defrost ice with a knife or metal objects —you can damage the evaporator.
Rules for operating a two-chamber refrigerator:
- 📦 Use vacuum containers or zip-lock bags for storage.
- 🧊 Defrost food in the refrigerator compartmentrather than in the freezer.
- 🌬️ Leave a gap 2-3 cm between products for air circulation.
- 🧼 Wash the freezer once every 3 months vinegar solution (1:1 with water).
If you follow all the rules, but ice still appears, it is a technical problem, and you cannot do without repairs.
FAQ: Answers to frequently asked questions
Why in the refrigerator Atlant MXM-170 is ice freezing on the back wall of the freezer, although the system is No Frost?
In models Atlant s No Frost Ice on the back wall of the freezer usually indicates a malfunction. fan (should blow cold air when the door is open). Defrosting heating element or defrost timer. Check:
- Is the fan working (should blow cold air when the door is open).
- Is there ice on evaporator (hidden behind the back panel).
If ice appears after 5+ years of operation, the heating element has most likely failed (replacement cost ~2,000 ₽).
Is it possible to replace the rubber seal on the refrigerator yourself Samsung RL-34?
Yes, but there are nuances:
- Buy original an elastic band for your model (the article number can be found in the instructions or on website Samsung).
- Remove the old seal, starting from the corners (latches or screws are usually hidden there).
- When installing a new seal heat it with a hairdryer (temperature 50-60°C) so that it is tighter sat down.
If after replacement there are gaps left, check door hinges (maybe they have sagged).
What to do if the freezer in the refrigerator Indesit DF 5200 is covered with ice and the refrigerator compartment does not cool?
This is a typical symptom freon leaks or clogging of the capillary tube. models Indesit with one compressor (like DF 5200), the freezer freezes first, since it is closer to the evaporator. Actions:
- Turn off the refrigerator and defrost for 24 hours.
- If after turning on the problem repeats, call a technician to diagnostics of freon pressure.
How often should you defrost a refrigerator with No Frost?
Manufacturers claim that refrigerators No Frost do not need defrosting. However, in practice it is recommended:
- once a year — for hygienic cleaning (removing bacteria, mold).
- When ice appears - if the system fails (for example, after a power outage).
- After a long period of inactivity (more than 2 weeks).
To defrost, just turn off the refrigerator for 6-8 hours (ice in No Frost melts faster than in drip systems).
Why, after replacing the compressor in the refrigerator Beko CN 335120 the freezer began to freeze more?
Possible reasons:
- Incorrect freon charging —too much or too little refrigerant leads to an imbalance of temperatures.
- Inconsistency of the compressor power —if a compressor of the wrong model is installed, it can operate in extreme mode.
- Damage to the capillary tube during repairs - leads to uneven distribution of the refrigerant.
Contact the service center where the repair was carried out - under warranty they are required to eliminate the malfunction (warranty period for repair work - 3-6 months).
