Correct setting of the temperature in the refrigerator Pozis —this is not just a matter of comfort, but a key condition for the safety of your products and the durability of the unit itself. Incorrectly set values can lead to rapid spoilage of food or, conversely, to deep freezing, which is especially important for refrigerators. Modern and classic models of this brand are equipped with various control systems, from mechanical thermostats to electronic units.
The owner is often faced with a situation where the products in the back of the chamber are covered with an ice crust, and on the door, on the contrary, they begin to sour. This is a direct signal that microclimate the inside of the device is broken. Understanding the operating principles of your specific device will allow you to avoid such problems without calling a specialist.
In this article we will analyze in detail all the nuances of the settings, consider the differences between models with electronic control and mechanics, and also give advice on diagnosing faults. A competent approach to adjustment will help you optimize the operation of the compressor and reduce energy consumption.
Principles of operation of the thermostat and types of control
The basis of climate control in the refrigerator is thermostat or an electronic sensor. Older and budget models Position use a mechanical regulator, which is a simple device that opens the electrical circuit when the set temperature is reached. The user controls it using a rotary knob with digital symbols.
The numbers on the scale of a mechanical thermostat do not mean degrees Celsius. They denote cooling intensity. The higher the number, the colder it will be inside the chamber. This is a common mistake made by users who confuse the scale divisions with the actual temperature. Switching to the “maximum” position makes the compressor work almost without stopping.
In models with a system No Frost or electronic control of the process, a complex control unit is in charge. Here the temperature is set with an accuracy of a degree through the display on the door or a hidden panel. Electronics independently controls the operation of the evaporator and fans, maintaining the set parameters with a minimum error.
⚠️ Attention: Mechanical thermostats have play and error. If the knob is on the "3" mark, this does not guarantee exactly +4°C, but only indicates the average cooling power.
Understanding the type of device you have is critically important before starting any manipulations. Trying to find the degrees on a mechanical knob is useless, since the principle of power gradation works there power gradations.
Setting a mechanical thermostat
If your refrigerator Position is equipped with a rotary knob inside the refrigerator compartment (usually at the top left or on lampshade), you are dealing with mechanics. Adjustment here is made by trial and error, based on the manufacturer's recommendations. The standard scale usually has values from 1 to 5, 6 or 7, as well as a position of "0" or "Off".
For everyday use, the optimal position of the handle between the divisions 2 and 3 (for a 5-step scale) or 3 (for 7-speed). This position provides a balance between cooling quality and compressor load. Setting the maximum value leads to intensive ice growth and a reduction in the service life of the motor.
If you notice that the food in the depths of the chamber is freezing, and the knob is at maximum, you need to reduce the power. Turn the knob counterclockwise one notch and wait a few hours. Stabilization of the temperature regime is not an instantaneous process; the inertia of the system can take up to a day.
⚠️ Attention: Never turn the handle of a mechanical thermostat sharply or forcefully. Smooth movement will prevent damage to the shaft and internal contacts of the device.
In the summer, when the room is hot, you may need to increase the cooling by moving the handle to the right. In winter, when the air in the room is cool, the load should be reduced.
Temperature adjustment in models with electronic control
Modern refrigerators Position, such as series RF or Fridge with a display, allow you to set the exact temperature in degrees Celsius. Control is carried out through touch buttons or a hidden panel, which is activated by a certain press. The display shows the current indicators for the refrigerator and freezer compartments separately.
To change parameters, you must unlock the control panel (usually by long pressing the button with the image of a lock). After unlocking, select the camera you want to configure using the "+" or "-" buttons. The recommended temperature for the refrigerator compartment is +2..+4°C, and for the freezer - -18°C and below.
The electronic system allows you to activate special modes such as Super Freeze (Super Freeze) or Eco. Quick Freeze mode forces the compressor to run for an extended period of time to quickly cool large quantities of fresh food. After the cycle is completed (usually after 8-24 hours), the refrigerator automatically returns to standard settings.
Do not unnecessarily set the minimum possible values, for example -24°C in the freezer. This leads to excessive energy consumption and unnecessary load on the system refrigerantwithout benefiting products that are already frozen.
Optimal temperature conditions for different products
There is no universal temperature for all products, so it is important know how to distribute inventory on shelves. The refrigerator compartment Posis has temperature zones. It is warmest on the top shelf and in the door (+6..+8°C), where it is better to store drinks, sauces and products that will be used soon.
The middle shelves and the fresh meat area (if there is one) provide a mode of about +2..+4°C. These are ideal conditions for storing dairy products, ready meals, sausages and cheeses. It is in this area that bacteria multiply slowest, keeping food fresh.
The bottom shelf above the vegetable drawers is the coldest area in front of the freezer. Here the temperature can drop to +1..+2°C. This is the best place to store perishable foods: fresh meat, fish, open canned food. The boxes below are designed for vegetables and fruits that do not need extreme cold.
| Product type | Recommended temperature | Storage area | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat/fish | 0..+2°C | Bottom shelf | 1-2 days |
| Dairy products | +2..+4°C | Middle shelf | 3-5 days |
| Vegetables and fruits | +4..+8°C | Bottom drawers | 3-7 days |
| Eggs | +2..+8°C | Door or shelf | up to 20 days |
Violation of zoning leads to the fact that in one part of the chamber the products wither, and in the other they become covered with frost. Correct distribution of reserves helps the thermostat operate in normal mode.
The influence of external factors on the operation of the refrigerator
The temperature inside the chamber Position directly depends on operating conditions. If the unit is placed near a stove, radiator, or in direct sunlight, the cooling system will be overloaded. In such conditions, even the maximum setting of the thermostat may not give the desired result.
The occupancy of the chambers also plays a role. An empty refrigerator cools down faster, but also heats up faster when the door is opened. A full chamber holds the cold better thanks to heat capacity products, but requires more time for initial cooling and disrupts air circulation if packed too tightly.
The frequency of door opening is another critical factor. Each opening lets in warm, moist air that condenses on the walls and food. If the refrigerator is often opened in the house, it makes sense to slightly increase the cooling power to compensate for heat gain.
It is important to ensure adequate ventilation of the rear wall of the device. The gap between the refrigerator and the wall should be at least 5-10 cm. Violation of this rule leads to overheating of the condenser and ineffective operation of the entire refrigeration system.
Diagnosis of problems: when adjustment does not help
There are situations when changing the thermostat settings does not bring results: the temperature does not drop or, conversely, food freezes even at minimum. This may indicate technical problems. The first sign of a problem is the constant operation of the compressor without shutdowns or too infrequent switching on.
One of the common causes of temperature violations is damage sealing rubber to the door. If the elastic does not fit tightly, warm air constantly enters the chamber. You can check this with a sheet of paper: hold it with the door and try to pull it out. If the sheet comes out too easily or does not hold at all, the seal requires replacement or adjustment.
Another possible reason is a refrigerant leak or a clogged capillary tube. In this case, the refrigerator may hum, but not cool. It is also worth checking the evaporator: if it is covered with an uneven “coat” or ice in only one place, this is a sign of problems with the system No Frost or defrosting.
⚠️ Attention: If you hear the thermostat clicking, but the compressor does not start, or the motor hums and immediately turns off, do not try to repair the device yourself. This requires the intervention of a specialist with a pressure manifold.
In case of suspected breakdown, the first step should always be to completely defrost the refrigerator within 24 hours with the power turned off. Sometimes this helps eliminate ice plugs in the condensate drainage system.
Frequent errors during operation
Many users make mistakes that ruin all setup efforts. One of the most common is installing a refrigerator in an unheated room (on a balcony or in a garage). Climate class Posis usually involves operating at ambient temperatures from +10°C to +32°C (or +43°C).
At temperatures below +10°C, the oil in the compressor thickens, which leads to its breakdown at startup. If the ambient temperature is too high, the refrigerator simply will not be able to remove heat, and the thermostat will constantly drive the motor, trying to achieve the set values.
Another mistake is ignoring the sounds of the unit operating. A normal refrigerator Posis makes background noise, but should not knock, whistle or gurgle loudly. A change in the acoustic profile often precedes a change in temperature indicators.
Regular checking of the settings and condition of the device is the key to its long service. Do not be afraid to experiment with the position of the thermostat within reason, observing the reaction of the system.
FAQ: Frequently asked questions
Why does ice freeze on the back wall in the Pozis refrigerator?
This can happen for several reasons: the temperature is set too low (the knob is at maximum), the seal is damaged doors, or you often leave the door open. The drain hole may also become clogged. Try to defrost the unit and set the thermostat to the average value.
What temperature should you set in the Pozis freezer?
The optimal temperature for long-term storage of food in the freezer is -18°C. This value allows you to maintain the structure of products and stops the growth of bacteria. For short-term storage, you can set it to -14..-16°C to save energy.
What to do if the refrigerator does not maintain the temperature after defrosting?
If after complete defrosting (at least 24 hours) and turning on the mains, the temperature does not drop within 5-6 hours, there may be a freon leak or the compressor has failed. In this case, diagnostics by a specialist is necessary.
Is it possible to regulate the temperature separately in each chamber?
In models with electronic control - yes, there are separate sensors and displays for the refrigerator and freezer compartments. In models with one mechanical thermostat, only the temperature of the refrigerator compartment is regulated, and the freezer operates in a dependent mode (the colder it is in the HK, the colder it is in the MK).
Why does the refrigerator get very hot on the sides?
In modern models Posis the condenser (heat exchanger) is often built into side walls of the housing. Heating of the sidewalls to 40-50°C during operation is a normal physical phenomenon of heat removal. If the walls become hot to the point that it hurts to touch them, check the ventilation and cleanliness of the rear grille.
