Owners of modern household appliances are often faced with the need to change the standard operating mode of the unit. Situations where this is required may arise for various reasons: seasonal storage of vegetables, temporary use of only the refrigeration compartment, or preparing equipment for long-term downtime. In the line of equipment turn off the freezer, can arise for various reasons: seasonal storage of vegetables, temporary use of only the refrigerator compartment, or preparing equipment for long-term downtime. In the equipment line Samsung this function is implemented quite flexibly, but requires a careful approach to the electronic control settings.
Many users mistakenly believe that to stop freezing it is enough to simply increase the temperature to the maximum value. However, in modern models with a system No Frost and electronic control, the logic of the compressor and fans is more complex. Complete shutdown of the freezer without stopping the refrigerator compartment is only possible through a hidden service menu or a special Cool Off mode Plus. The usual thermostat adjustment will not stop the cooling cycle completely, but will only change the target temperature.
In this article we will analyze in detail all the available methods for controlling the climate in the freezer. You will learn how to activate the vacation mode, how to enter the service menu to force the freezer compressor to stop, and what nuances should be taken into account when operating equipment in non-standard modes. It is important to understand the difference between a software shutdown and a physical shutdown so as not to harm the control system.
Why you may need to turn off the freezer
The need to isolate the freezer compartment from the cooling process occurs infrequently, but it can be critical. For example, if you are going away for a long time and want to leave only the main drinks compartment on, but are afraid of an odor in the empty freezer. Or there is a situation when the freezer is full, and you urgently need to defrost some of the food without touching the rest of the supplies in the refrigerator.
Also, shutdown is necessary when carrying out preventive maintenance. If you notice that ice is forming on the bottom of the unit or that there is strange noise, temporarily stopping the freezer compressor will help diagnose the problem. In some models Samsung with the system Triple Cooling each circuit operates independently, which allows flexible management of energy consumption.
⚠️ Attention: Prolonged shutdown of the freezer compartment while the main compartment is running can lead to changes in the humidity inside the empty freezer. It is recommended to periodically check the condition of the internal space to avoid the appearance of mold or foreign odors.
There are several scenarios when manipulations with temperature conditions become mandatory:
- 🧊 The need to quickly defrost individual products without losing cold in the upper compartment.
- 🔌 Preparing equipment for transportation or long-term storage without food.
- 💡 Diagnosis of malfunctions of the fan or defrosting heating element in the lower chamber.
- 📉 Energy savings during periods when freezing is not required (seasonal use).
Cool Off Plus mode: software shutdown
The safest and manufacturer-recommended way to stop cooling in the freezer is to use the function Cool Off Plus. This mode is designed specifically for situations where you need to stop freezing, but keep the refrigerator compartment running. Unlike standard Holiday, which simply raises the temperature, Cool Off Plus actually stops the flow of refrigerant to the freezer's evaporator.
Activating this feature on the control panel usually requires pressing and holding two buttons at the same time. Most often this is a combination of Freezer and Power Freeze, or Fridge and Power Cool, depending on the specific model of your Samsung. You must hold the buttons for 3-5 seconds; the corresponding indicator or inscription will not appear on the display Cool Off.
After activating the mode, the temperature in the freezer will begin to gradually increase. It is important to note that the compressor may continue to operate to maintain cold in the upper compartment, but the freezer fan and the supply of freon to its circuit will be blocked. This allows you to avoid defrosting food in the main chamber.
If the display lights up Cool Off, this means that the mode has been successfully activated. To return to normal operation, you must press the same combination of buttons again. The indicator will go off and the system will automatically begin cooling the freezer to the previously set values.
Service menu: forced stop of the compressor
For deeper diagnostics or in cases where standard methods do not produce results, you can use the service menu (Service Mode). This method allows you to forcefully turn off the compressor or fan of a specific chamber. Be careful: tampering with the factory settings requires precision, since incorrect actions can lead to resetting the calibration of the sensors.
To enter the service menu on most models Samsung, you must simultaneously hold down the buttons Freezer and Lighting (or Fridge and Freezer depending on the series) for 8-12 seconds. A characteristic sound signal will be heard, and a code will appear on the display, for example 00FF or 11FF. Navigation through the menu is carried out using the temperature adjustment buttons.
In the service mode, you can find options for forced on/off of components:
- ❄️ R-ON / R-OFF: turning on or off the main compressor.
- 🌀 FAN-ON / FAN-OFF: control of the evaporator fans.
- 🔥 DEF-ON / DEF-OFF: starting or stopping the cycle defrost.
- 🔇 BEEP: enable or disable the sound signals of the buttons.
To turn off the freezer, you need to find the parameter responsible for the compressor or fan of this chamber and switch it to the OFFstate. After completing the necessary manipulations, be sure to exit the service menu by turning off the power supply to the refrigerator for 1-2 minutes. This will save the changes and restart the controller in normal mode.
What to do if the buttons do not respond?
If the button combinations do not work, the control panel may be Child Locked. Find the button with the image of a lock and hold it for 3-5 seconds until the corresponding indicator appears. After unlocking, re-enter the menu.
Table of codes and indications for different series
The model range Samsung is extensive, and the symbols on the displays may differ. Below is a summary table that will help you navigate the notations when working with different series of refrigerators. Pay attention to the letter codes displayed instead of temperature numbers.
| Refrigerator series | Shutdown indication | Button combination | Features |
|---|---|---|---|
| Side-by-Side | Cool Off |
Freezer + Power Freeze (3 sec) | Double cooling cycle |
| RB (Bottom Freezer) | C-- / --F |
Fridge + Freezer (8 sec) | Service login required |
| RS (Multidoor) | OF OF |
Freezer + Eco (5 sec) | Smart diagnostics |
| RL (Top Freezer) | Absent | Mechanical regulator | Physical shutdown only |
If you see flashing symbols or error codes on the display (for example, 22E, 40C), this may indicate a malfunction temperature sensor, which makes software shutdown impossible. In such cases, checking the electrical circuits is required.
The nuances of the No Frost system when turned off
The system No Frost implies constant air circulation. When you turn off the freezer programmatically, you stop cooling, but the fan may continue to move air between the compartments if the dampers are not closed. In modern models Samsung with two compressors (Twin Cooling) this risk is minimal, since the circuits are completely decoupled.
However, in models with one compressor, turning off the freezer through the menu Cool Off closes the cold air supply damper from below. However, residual cold or heat from the refrigerator compartment may gradually penetrate into the lower compartment. Therefore, you should not expect that the temperature there will remain subzero indefinitely.
It is important to remember about condensation. When the freezing cycle is stopped, moisture may appear on the walls. The water drainage system in the models No Frost is designed to operate in the normal cycle. If the water does not have time to evaporate, it may leak under the drawers. Check the drainage hole regularly.
Checklist for preparing for shutdown
Before you begin manipulating the settings, make sure that you have completed all the preparatory steps. This will help avoid food spoilage and failure of electronics.
☑️ Preparing to turn off the freezer
First you need to remove all the products. Even if you simply increase the temperature, stopping freezing for a long time will lead to spoilage of meat, fish and semi-finished products. If there is ice in the chamber, it is better to remove it mechanically before switching to the mode Cool Offto prevent water from flowing into the technical holes when melting.
Check the stability of the unit. When switching to different modes, the compressor may change speed, which sometimes causes vibration. Make sure that the legs of the refrigerator fit snugly to the floor.
⚠️ Attention: Specifications and button locations may vary depending on the year of manufacture and specific modification. Always check the official instructions (User Manual) for your model, available on the manufacturer’s website or in the SmartThings application.
Frequently asked questions (FAQ)
Is it possible to completely turn off a Samsung refrigerator with one button?
Most modern models do not have a physical full shutdown button on the body. To completely turn off the power, you must remove the plug from the socket. A software shutdown via the control panel usually puts the equipment into sleep mode or demonstration mode, but does not guarantee complete shutdown of all circuits.
How long does the cold last after turning off the freezer?
When the door is closed and filled with food (or special cold accumulators), the temperature in the chamber can remain low for up to 10-15 hours. An empty chamber will lose cold much faster, in 2-4 hours, especially in a hot room. Is frequent switching of modes harmful for a compressor? loads. However, sudden transitions from deep-freeze mode to shutdown mode and back more than once a day are not recommended, as this creates stress for the lubrication system and electronics.
Is frequent mode switching harmful to the compressor?
Modern inverter compressors Digital Inverter from Samsung designed for frequent load changes. However, sudden transitions from deep freeze mode to shutdown mode and back more than once a day are not recommended, as this creates stress on the lubrication system and electronics.
What does error code 22E mean after an attempt to shutdown?
The code 22E indicates a malfunction of the freezer temperature sensor. If it appears after manipulating the menu, the contact or the sensor itself may have been damaged. In this case, it is impossible to turn off the camera on your own - the sensor needs to be replaced.
Is it possible to use the Cool Off Plus mode in the summer?
Yes, you can. However, in summer, when the ambient temperature is high, heat exchange occurs more intensely. If you turn off the freezer in the summer, keep the door tightly closed, otherwise condensation will quickly form inside and the humidity will increase.
