Technology No Frost in refrigerators Samsung promises to save users from manual defrosting, but in practice many encounter icing under the plastic drawers of the freezer. Paradox: the system should prevent ice formation, but ice still appears. What's the matter?
The reasons lie both in design features Samsung No Frostand in operating errors. For example, in 80% of cases, the problem is related to a clogged drain hole or a malfunction of the evaporator heater - details that users rarely check on their own. In this article, we will analyze all possible scenarios: from a banal overload of the chamber to serious breakdowns requiring the intervention of a technician.
It is important to understand: No Frost does not mean “no ice at all.” The system simply transfers the frost to a hidden area (the evaporator), where it melts under the influence of a heater. If this process is disrupted, ice begins to accumulate in visible places, including the space under the boxes. Next is a detailed analysis with step-by-step instructions and warnings about common errors.
1. How No Frost works in Samsung refrigerators: why ice still appears
The technology No Frost (or Frost Free) in models Samsung is based on forced air circulation and automatic defrosting of the evaporator. The fan distributes the cold evenly, and the heating element periodically turns on to melt ice on the hidden evaporator. The water flows into the drainage hole and evaporates.
However, the system is not ideal. This is why ice can form under the drawers:
- 🔄 Violation of the defrosting cycle: if the evaporator heater is broken or the defrost timer is off, frost does not melt and accumulates.
- 💧 Drainage clogged: water does not go into the pan, freezes and forms an ice “coat” under drawers.
- 🌡️ Incorrect temperature: at too low values (below −24°C), moisture condenses and freezes faster than the system can remove it.
- 🚪 Frequent opening of the door: warm air increases humidity, which No Frost does not always have time to process.
In models Samsung with a system Twin Cooling Plus (double cooling circuit), the problem may be aggravated due to separate evaporators for the refrigerator and freezer compartments. If one of the circuits is not working correctly, ice will appear in its zone.
2. TOP 7 reasons for icing under drawers and how to diagnose them
Before disassembling the refrigerator, check these points. Majority of problems are solved without calling a specialist:
- Clogged drainage hole. Signs: water under the boxes, ice in the form of “stalagmites”. Solution: clean the hole with a cotton swab or a special brush (included with some models Samsung).
- Door not closed tightly. You can check with a piece of paper: if it is easily pulled out from under the seal, the tightness is broken. Adjust the hinges or replace the rubber band.
- Overloading the freezerDrawers should not touch the back wall - this blocks air circulation. Remove excess food and leave a gap of 2-3 cm.
- High humidity in the chamberStoring liquid foods without lids or hot foods. condensation. Use containers with sealed lids.
- Fan malfunction. data-i="90">. Ice builds up evenly along the entire back wall. Replacement of the part is required (it is not recommended on your own).. If it does not rotate, the cold is distributed unevenly. Shine a flashlight into the back of the chamber - the blades should rotate.
- Failure of the evaporator heater. Ice builds up evenly along the entire back wall. The part needs to be replaced (doing it yourself is not recommended).
- Electronic module failure. The refrigerator may freeze in freezing mode. Try resetting the settings by turning off the power for 10 minutes. data-i="93">Electronic module failure
For models Samsung with a display (for example, series RB, RS), check the error codes. If it lights up E F or E H , this is a signal of problems with defrosting or fan.

3. Step-by-step instructions: how to remove ice under the boxes with your own hands
If the cause is not a serious breakdown, follow this algorithm. Before you begin unplug the refrigerator!
Step 1. Defrosting and cleaning
- ❄️ Take out all the food and boxes. Place them in a bowl of cold water (so they don’t melt quickly).
- 🧊 Place a tray under the drainage hole (the water will drain). there).
- ⏳ Wait for complete defrosting (8-12 hours). Do not use a hair dryer or hot water - this will damage the plastic!
Step 2. Cleaning the drain
Take a syringe (without a needle) with warm water and rinse the hole. If the blockage is severe, use it. wire with a diameter of 1–2 mm. In models Samsung the drainage is often located under the bottom drawer on the right.
Step 3. Checking the fan and evaporator
After defrosting, turn on the refrigerator and listen:
- 🔊 The fan should start in 5-10 minutes. If not, it may be frozen or broken.
- 🔥 The evaporator (back wall) should be slightly warm after 30-40 minutes of operation. If it is cold, the heater does not work.
Step 4. Setting the temperature
Set the mode Power Cool (if available) for 2-3 hours, then return to standard −18°C. In models with SmartThings check the settings through the application.
4. When to call a technician: signs of serious breakdowns
Not all problems can be solved yourself. Contact the service center Samsungif:
- ⚡ The refrigerator is electrocuted or sparks. when turned on.
- ❄️ Ice builds up evenly along the entire back wall (even after defrosting).
- 🔊 The fan does not turn on at all, although there is power.
- 📛 An error appears on the display
E 01,E 02orE 04(problems with sensors). - 💸 The compressor works non-stop, but the temperature in the chamber does not drop below −10°C.
Average cost of repairs (in Moscow, 2026):
| Breakage | Price (RUB) | Repair period |
|---|---|---|
| Replacement of evaporator heater | 3 500–5 000 | 1–2 days |
| Cleaning or replacing drainage systems | 2 000–3 500 | 1 day |
| Repair of electronic module | 4 000–7 000 | 2–3 days |
| Fan replacement | 2 500–4 000 | 1 day |
⚠️ Attention: If the refrigerator is under warranty, do not disassemble it on your own! Samsung may refuse free repairs if there are signs of interference.
5. Prevention: how to prevent ice from forming in the future
To prevent the problem from recurring, follow these rules:
- 📅 Defrost the refrigerator every 6-12 monthseven if it is No Frost. This removes hidden ice from the evaporator.
- 🍲 Store liquid products only in airtight containers. Open pots of soup are the main source of moisture.
- 🔄 Do not put hot foods in the freezer. Wait until they cool to room temperature.
- 🧊 Do not overload the camera. Air must circulate between products.
- 🔧 Check the seal once every 3 months. Wipe it with a weak solution of soda (1 tablespoon per 1 liter of water).
For models with the function CoolSelect Zone (for example, Samsung RB37J5240SA) set the "Flex" zone to the optimal temperature of −15°C. This will reduce the load on the system No Frost.
⚠️ Attention: If your region has hard water, the drainage hole will clog faster. Rinse it with a vinegar solution (1:1 with water) once every 3 months.
What will happen if you ignore the ice under the drawers?
First, the ice will begin to occupy useful space, then:
1. The load on the compressor will increase → an increase in energy consumption by 20–30%.
2. Products will freeze worse due to impaired air circulation.
3. Risk of breakdown of the fan or evaporator heater (repair will cost 3–5 thousand rubles).
4. In severe cases, ice can deform plastic drawers or damage the door seal.
6. Common mistakes made by users when removing ice
Many actions that seem logical only aggravate the problem. Here's what you can't do:
- 🔪 Crack off the ice with a knife or fork. This will damage the plastic and may pierce the freon tube.
- 🔥 Use a hair dryer or boiling water. A sharp temperature change deforms the seal and plastic parts.
- ❄️ Put the refrigerator on maximum mode (
Super Freeze) for a long time. This overloads the compressor and accelerates icing. - 🧹 Clean the drainage with metal objects. Use only plastic or wooden sticks.
- 🔌 Turn on the refrigerator immediately after defrosting. Wait 30–60 minutes for the moisture to evaporate.
If you doubt your actions, watch the official video instructions Samsung for your model. For example, for the series RS6*** there are separate videos on system care No Frost.
7. Comparison of No Frost in Samsung with other brands: why this happens
Technology No Frost works differently for different manufacturers. That's why in Samsung ice appears under boxes more often than in LG or Bosch:
| Brand | Features No Frost | Tendency to icing |
|---|---|---|
| Samsung | The evaporator is located vertically, the drainage is narrow. Models with Twin Cooling two circuits, which complicates the system. | High (especially in the freezer) |
| LG | The evaporator is horizontal, the drainage is wider. The system Smart Inverter adapts to the load. | Average |
| Bosch | Use LowFrost a hybrid of the drip system and No Frost. Fewer moving parts. | Low |
| Indesit | Budget models with a simplified system. The drainage often becomes clogged. | Very high |
In Samsung the problem is aggravated by the fact that many models have crying evaporator (defrost) only in the refrigerator compartment, and the freezer remains vulnerable. For example, in the series RB3*** ice under the drawers is a common user complaint.
⚠️ Attention: Design details No Frost may vary even within the same brand. For example, in Samsung RS552NRUA1 the drainage hole is located on the left, and in RB30J3200SS on the right. Always check the instructions for your model!
FAQ: Answers to frequently asked questions
Can I use salt or vinegar to speed up defrosting?
No! Salt corrodes metal parts, and vinegar can damage plastic and rubber seals. To speed up defrosting, place a bowl of hot (not boiling!) water in the chamber and close the door for 20–30 minutes. Repeat the procedure until the ice melts.
Why does ice appear again after a week after defrosting?
This is a sign of a malfunction of the evaporator heater or defrost timer. In normal mode, the defrost cycle occurs every 8–12 hours of compressor operation. If the heater does not turn on, frost will accumulate. A technician needs diagnostics.
Only one drawer in the Samsung No Frost refrigerator freezes over. What's the matter?
Most likely, this box is too close to the back wall and is blocking air circulation. Move it to another place, leaving a gap of 2-3 cm. Also check whether the box itself is deformed (sometimes the plastic cracks and clings to the walls).
Is it possible to replace the evaporator heater yourself?
Theoretically, yes, but this is a complex process that requires disassembling the back panel of the freezer and working with freon contour. Without experience, you risk damaging the tubes or connecting the part incorrectly. The average cost of replacement in the service is 3,500–5,000 rubles, which is cheaper than repairs after errors.
How often do you need to change the rubber seal in Samsung No Frost?
The service life of the seal is 5–7 years with proper care. Change it if:
- The rubber has lost elasticity and does not return to shape after compression.
- Cracks or tears appear on it.
- The door no longer closes tightly (check with a sheet of paper).
The original ones are suitable for replacement rubber bands Samsung (the article depends on the model) or universal ones, for example, from Midea.
