Owners of refrigeration equipment are often faced with the need to change the temperature conditions of the equipment. For example, during a long departure or if the freezer compartment is temporarily not in use, the question arises of how to turn off the freezer compartment in the Stinol refrigerator. This desire is dictated by the desire to save energy or prevent the appearance of unpleasant odors in an empty compartment.
However, the technical implementation of this task depends on the specific model of your device. Most household refrigerators of the brand Stinol, especially older series, are equipped with one compressor that serves two cooling circuits at once. In such systems, separate temperature control is not possible without intervention in the design or the use of external timers.
However, there are ways to minimize energy consumption or completely stop the unit, if necessary. In this article, we will analyze in detail the design features of various models, consider operating modes and determine what actions will be safe for the compressor and products.
Design features of Stinol refrigerators
To understand the possibility of turning off a separate chamber, you need to refer to the design of the refrigeration circuit. Classic models Stinol, such as the popular series 101, 102, 103, 104 and 107, are built on the basis of a single compressor. The refrigerant passes through the freezer evaporator and then through the refrigerator compartment evaporator. Temperature control occurs mechanically, through a damper or thermostat, but the source of cold is common.
More modern models can be equipped with a system No Frost or full technology No Frost, where air circulation is forced. Even in such systems, if there is only one compressor, stopping freezing, leaving cooling in the upper compartment, is technically impossible using standard means. The compressor either works on both circuits or turns off completely.
⚠️ Attention: Attempts to pinch the capillary tube or resolder the circuits to separate the operation of the chambers at home will lead to loss of warranty and a high probability of compressor failure due to violation of the design pressure.
There are two-compressor models, where each chamber has its own independent unit. In this case, it is theoretically possible to disable one of them, but on the control panel of such Stinol refrigerators it is rare to find a function to completely disable one of the chambers without turning off the device from the network. Usually only the temperature is regulated.
Is it possible to turn off the freezer separately
The answer to this question lies in the technical characteristics of your device. If you have a classic single-compressor refrigerator, then there is no standard way to turn off only the lower compartment. The thermostat, located inside the refrigerator compartment or on the panel, controls turning the motor on and off depending on the air temperature in the upper compartment.
Some users try to use the “Super Freeze” mode, believing that turning it off will stop the freezer. This is a misconception. The mode Super Freeze only forces the compressor into continuous operation, ignoring the thermostat readings, but does not allow isolated control of the circuits.
In models with electronic control and display, the “Vacation” or “Eco” function is sometimes found. However, in Stinol refrigerators, this function, as a rule, switches the refrigerator compartment to economy mode (about +15°C), leaving the freezer operating at full capacity so that food does not go to waste. The opposite effect - a working “warm” refrigerator compartment and a switched off freezer - cannot be achieved.
Why can’t you just turn off the freon supply?
Stopping the access of refrigerant to one of the evaporators will lead to a sharp increase in pressure in the system. The compressor will work non-stop, trying to pump gas, which will cause it to overheat and eventual failure in a short time.
Using the “Super Freeze” mode and thermostat
Although you cannot completely turn off the freezer separately, you can influence the intensity of its operation. The thermostat is located on the front panel or inside the refrigerator compartment. It has a scale from minimum to maximum (often 1 to 5 or 7). By setting the knob to the minimum position, you will reduce the frequency of the compressor switching on.
Mode Super Freeze (super freezing) is activated by a button with the corresponding designation or by turning the knob to the extreme position (often a red dot or the inscription Max). When activated, the indicator light comes on. In this mode, the compressor does not turn off, providing fast freezing of products.
- ❄️ To save energy, set the thermostat to a position corresponding to the temperature of +4...+5°C in the refrigerator compartment.
- ⏱️ Do not keep the super freezing mode on for more than 24 hours unless necessary, this increases wear of parts.
- 🌡️ If you are leaving for a long time, it is better to defrost the freezer and leave the doors ajar than to try to set the minimum cold.
It is important to understand that even at the minimum thermostat settings, the temperature in the freezer compartment of a single-compressor Stinol will drop to -18...-24°C when the motor is running. The only difference is the duration of the pauses between switching on.
Algorithm for completely turning off the refrigerator
If your goal is to leave the equipment for a long period (for example, during a vacation or repair), it is better to turn off the entire unit. This is safe for the compressor and the electrical network. Before this, it is necessary to carry out a number of preparatory steps to avoid the appearance of mold and unpleasant odors upon return.
You should first defrost the freezer. Even in systems No Frost it is recommended to carry out preventive defrosting once a year. Turn off the device from the network, remove all products and leave the doors open until the water has completely drained and the internal surfaces have dried.
☑️ Preparing for a long shutdown
After drying, wipe the seals with glycerin or a special lubricant so that the rubber does not dry out during downtime. It is better to wind up the power cord and secure it at the back, and move the refrigerator itself away from the wall, ensuring ventilation.
⚠️ Attention: Never plug in the Stinol refrigerator immediately after moving it if it was lying on its side. The oil must drain into the compressor crankcase; this requires 4 to 12 hours of rest in a vertical position.
Nuances of working with electronic control
In newer or modified Stinol models, an electronic control panel may be found. Here, temperature settings are made in 1 degree increments. However, the operating logic remains the same for single-compressor systems: one motor for two circuits.
If fault indicators are lit on the display or the temperature conditions do not correspond to the set ones, diagnostics may be required. Electronics controls not only the compressor, but also fans, defrost heating elements (in No Frost) and backlight lamps.
| Parameter | Mechanical control | Electronic control |
|---|---|---|
| Setting accuracy | Approximate (on scale) | Accurate (up to 1°C) |
| Indication | LEDs (network, freezing) | Digital display |
| Adjustment | Rotary knob | Touch buttons |
| Possibility of separate shutdown | No | No (in 95% models) |
If there is a malfunction in the electronic control unit, the refrigerator may behave incorrectly: it may not turn off or not gain temperature. In such cases, reconfiguring the buttons will not help; you need to call a technician to check the sensors.
Frequent errors when trying to modify
The desire to save electricity sometimes pushes owners to risky experiments. The most common mistake is setting an external timer that turns off the refrigerator for several hours. This is strictly prohibited for modern compressors.
Frequent on and off cycles (less than 10-15 minutes after stopping) lead to water hammer. Liquid refrigerant or oil does not have time to return to the crankcase, and the compressor tries to compress the liquid, which leads to mechanical destruction of the valves.
- 🚫 Do not use household socket timers to cycle the refrigerator.
- 🚫 Do not seal the air ducts between the chambers, this will disrupt circulation and lead to food spoilage in the top compartment.
- 🚫 Do not try to disconnect the freezer temperature sensor to “trick” the system - this will cause the motor to run continuously.
The only safe way to “turn off” the freezer is to stop using it, defrost it, and keep the door open while the main refrigerator is running. But this is only possible if the design allows you to isolate odors, which is difficult to do in Stinol.
What to do if the freezer stops freezing, but the refrigerator is working?
This is a common malfunction, not a function. In single-compressor Stinol systems, this may mean a freon leak (gas leaves the freezer circuit first), a clogged capillary tube, or a thermostat malfunction. Repair is required.
Is it possible to use the Stinol refrigerator only as a refrigerator by sealing the outlet to the freezer?
Theoretically it is possible, but ineffective. The compressor will work in increased mode, since the thermostat is in a warm chamber, and the evaporator of a cold chamber will freeze unevenly. This will reduce the service life of the equipment.
Why does the refrigerator take a long time to gain temperature after defrosting?
After complete defrosting, the system takes time (from 2 to 6 hours) to reach operating mode. Do not load food into a warm chamber, let it run idle until the specified parameters are reached.
Does the temperature in the room affect the ability to turn off the freezer?
Yes. If the room is cold (below +10°C), the thermostat may not turn on the compressor at all, and the freezer will “turn off” by itself, which will lead to defrosting of food. In winter, Stinol refrigerators require special attention.
How to properly transport Stinol if the freezer is no longer needed?
If you decide to use the freezer forever, it is better to recycle the equipment and buy a model without it (for example, a refrigerator). Transporting a full refrigerator requires maintaining a vertical position.
In conclusion, it is worth noting that the design of refrigerators has been tested for decades and is reliable precisely due to its simplicity. Attempts to modernize them for separate control often upset this balance. If you critically need independent control, consider purchasing a specialized chest freezer or a two-compressor model, where such functionality is built into the design.
