In situations where the main refrigeration compartment fails, and food urgently needs to be preserved, or when moving, when new appliances have not yet been connected, owners of household appliances have problems a reasonable question about replacing the functions of nodes. Often the idea comes to mind to switch freezer compartment to gentle cooling mode so that it works like a regular refrigerator. Theoretically, since a freezer is the same refrigeration unit, but with lower temperature thresholds, such a transformation seems quite logical and feasible.
However, the actual operation of equipment in abnormal modes is always associated with risks for the compressor and the quality of the stored products. Modern models equipped with complex electronics that can block operation if you try to set incorrect parameters. At the same time, old mechanical units often allow you to adjust the thermostat over a wide range, which formally makes it possible to raise the temperature above the freezing point of water.
In this article we will analyze in detail the technical aspects of such resetting, the impact on the shelf life of various groups of products and possible consequences for the equipment itself. You will find out under what conditions this is acceptable, and when it is better not to risk expensive equipment.
Fundamental differences temperature conditions
The fundamental difference between the refrigerator and freezer compartments is the target temperature range that is maintained inside the chambers. Standard refrigerator operates in the range from +2 to +8 degrees Celsius, which is ideal for slowing down the growth of bacteria, but does not stop biochemical processes completely. Under these conditions, products remain fresh for several days or weeks, maintaining their structure.
The freezer, in turn, is designed for deep freezing, where the temperature drops to -18 degrees Celsius and below. At such values, the water in the food cells turns into ice, which completely stops the activity of microorganisms and fermentation. Thermostat or the electronic control module in the freezer is programmed to maintain negative values, ignoring positive signals from the sensors.
An attempt to use the freezer as a refrigerator requires overcoming this barrier. If the device allows you to raise the temperature to +4..+6 degrees, physically it will begin to work like a refrigerator. However, the design of the evaporator in the freezer is often not designed to operate in “warm” mode, which can lead to the formation of condensation or, conversely, insufficient cooling in different areas of the chamber. air circulation and the design of the evaporator in the freezer is often not designed to operate in “warm” mode, which can lead to the formation of condensation or, conversely, insufficient cooling in different areas of the chamber.
⚠️ Attention: Not all models allow you to set a positive temperature. In some No Frost systems, the fan operation algorithm is tied to defrost cycles, characteristic only for deep minus.
Technical possibility of resetting the thermostat
The question of the possibility of reconfiguration directly depends on the type of control of your household appliances. In mechanically controlled units, the temperature is controlled by thermostat a device that opens the compressor power circuit when a specified threshold is reached. The scale of such regulators often has divisions from 1 to 7 or from Min to Max. If you turn the knob to the minimum cooling position, the temperature inside can rise to 0 or even +2 degrees, which is already close to the refrigeration mode.
The situation with electronic control is more complicated. Here microcontroller receives data from the sensor and controls the compressor according to a strictly defined algorithm. The software of such boards often has a “cutoff” that does not allow the user to set the temperature above -5 or -9 degrees. This is done to prevent spoilage of products that the user is accustomed to storing in the freezer.
There are models with the function Super Freeze or Eco Mode, but they only temporarily change the operating mode without turning the chamber into a refrigerator. For a full conversion, either a special engineering menu (available to service engineers) or a physical replacement of the thermostat with an analogue with a different response range is required.
Is it possible to replace the thermostat yourself?
Replacing the thermostat requires opening the case, disconnecting the capillary tube of the sensor and refilling the refrigerant in case of damage to the system. This is a complex procedure that requires skills and tools, so it is better not to take risks without qualifications.
Impact on the quality and safety of food
Even if you managed to technically set the freezer to a temperature of +4°C, storing food in it will differ from a regular refrigerator. The main problem is convection. In freezers, especially No Frost systems, the fan circulates very dry and cold air. Products that are not hermetically packaged can quickly dehydrate, crust over, or erode, losing their presentation and taste.
In addition, the temperature distribution in the chamber volume may be uneven. At the back wall, where evaporatoris located, the temperature can be critically low, leading to freezing of vegetables and fruits, while at the door it will be higher than normal. This creates a risk of spoilage of sensitive products such as milk, meat or ready meals.
- 🥩 Meat and fish: At a temperature of about 0°C they are stored well, but the risk of drying out is high.
- 🥦 Vegetables and herbs: Strongly not recommended, as they can freeze walls or wither from dry air.
- 🥛 Dairy products: Require a stable temperature, jumps in the freezer can lead to delamination of the structure.
Risks for the compressor and consumption electricity
Using a freezer in refrigerator mode creates non-standard operating conditions for compressor. Since heat inflows at a positive ambient temperature (inside the chamber) are higher than at a negative temperature, the unit may have to work more intensively or, conversely, turn on and off too often. Frequent start-stops are harmful to the motor and the starting relay.
It is also worth considering electricity consumption. Freezers usually have more powerful insulation, but their compressors are designed to work “long” to maintain deep minus temperatures. When operating at high temperatures, the efficiency of the system may decrease, which will lead to an increase in electricity bills. data-i="100">Risk/Consequence electricity.
| Parameter | Standard mode (-18°C) | Refrigerator mode (+4°C) | Risk/Consequence |
|---|---|---|---|
| Compressor load | High (long-term) | Medium (cyclic) | Wear of starting relay |
| Humidity inside | Low (dry air) | High (condensation) | Icing of drainage |
| Energy consumption | Standard | Possibly higher than normal | Budget overrun |
| Sealant life | Stable | Accelerated wear | Loss of tightness |
Features of operating the No Frost system
Technology No Frost (without frost) implies constant air circulation through the evaporator hidden behind the chamber wall. In freezers, this process is set up to remove moisture from the air, preventing the formation of a snow coat. When the temperature rises to positive values, the air humidity inside the chamber will increase sharply (the products will begin to “breathe” more actively).
The defrost system may not be able to cope with the increased amount of moisture. As a result, water can begin to accumulate in the pan, freeze there (if part of the air path is still cold), or, worse, flow out. Fan, driving moist air, can become covered with ice faster than the defrost timer goes off, which will cause noise or stop the rotation of the blades.
In addition, No Frost freezers often lack balcony shelves on the door designed for storing bottles and cans, typical of refrigerators. This creates inconvenience in operation and can lead to products falling when opening.
⚠️ Attention: Prolonged operation of the No Frost system at high humidity can lead to failure of the defrost heating element or defrost sensor due to abnormal ice formation conditions.
Practical recommendations for setup
If you are determined to use the freezer as a temporary refrigerator, you need to carry out a number of preparatory steps. First, defrost the device completely and rinse it. Then try to set the minimum possible temperature through the control panel or thermostat adjustment. Be sure to use an external one to monitor the actual temperature inside the chamber, since the built-in indicator may lie or show only the target value. Place the thermometer in the center of the chamber, away from the walls.

☑️ Freezer preparation checklist
For products, use airtight containers to minimize the influence of dry air and odors. Do not fill the chamber completely, leave space for air circulation to avoid local overheating.
Alternative solutions and conclusions
Before overload your freezer, consider alternatives. If the main refrigerator is broken, you can temporarily transfer some of the food to balcony (in winter) or use thermal containers with ice. If the goal is to save space, it is better to purchase a separate chest or compact refrigerator than to operate the equipment in a mode not provided by the manufacturer.
In conclusion, technically turn the freezer into a refrigerator possible, but only in devices with mechanical control and a wide range of adjustments. For electronics this is often not possible without software intervention. The main risks are spoilage of products due to improper microclimate and accelerated wear of the compressor.
Be careful and always check the instructions for your model Indesit, Atlant, LG or any other. The manufacturer always indicates acceptable climatic classes and temperature ranges, beyond which the warranty will be voided.
Will the compressor burn out if you set it to +5 degrees in the freezer?
Most likely not, but its production life will be reduced. The compressor will operate in an irregular mode, turning on frequently. The main danger is not combustion, but failure of the start relay or lubrication failure due to changes in freon pressure in the system.
Is it possible to store vegetables in the freezer at +2 degrees?
It is highly not recommended. Even at above-zero temperatures, the dry air of the freezer (especially No Frost) will quickly dry out the vegetables and they will wither. In addition, there is a high risk of local freezing near the back wall, which will turn vegetables into mush after defrosting.
Why does the electronics not allow you to set the temperature above -5?
This is a software limitation set by the manufacturer to protect the products. The logic of the controller is based on the fact that frozen foods should be stored in the freezer, and raising the temperature to positive values will lead to their rapid spoilage.
How often do you need to defrost such an improvisation?
If you use the freezer as a refrigerator, the humidity inside will be higher. Check the condition of the evaporator and drain hole every 3-4 days. If ice or water appears at the bottom, forced defrosting will be required.
