How to adjust the temperature in a Stinol refrigerator: a detailed guide with photos and expert advice

Refrigerators Stinol have long established themselves as reliable equipment with a simple but effective control system. However, even with such proven models, owners often encounter problems: food freezes in the “freshness zone”, the freezer is covered with a thick layer of ice, or the compressor works without stopping. In 90% of cases, the reason lies in incorrect setting of the thermostat a mechanical or electronic device responsible for maintaining the climate inside the chambers.

In this article we will look at how accurately adjust the temperature in refrigerators Stinol different series (from classic STN 100 to modern STN RF 385), avoiding typical mistakes. You will learn what values ​​are considered optimal for storing different products, how to check the functionality of the regulator, and what to do if the refrigerator does not respond to changes in settings. All instructions are based on the manufacturer’s official manuals and the experience of service technicians.

Types of temperature controllers in Stinol refrigerators

Depending on the model and year of manufacture, refrigerators Stinol are equipped with one of three types of thermostats:

• 🔘 Mechanical rotary —a classic version with a handle (usually located inside the refrigerator compartment or on the top panel). Marked with numbers from 1 to 7 or symbols (for example, “Min”–“Max”).
• 📱 Electronic touch - found in premium segment models (for example, Stinol STN RF 420). Control is carried out using buttons or a touch panel, the temperature is displayed on the display.
• 🔧 Electromechanical is a hybrid version with a digital display, but a mechanical switch (for example, in the series STN 167).

It is easy to determine the type of regulator: if you you see dial with divisions - this is mechanics; if there is display and buttons - electronics. Hybrid models can have both. Important: in Stinol refrigerators with with two compressors (for example, STN 200), the regulators for the freezer and refrigerator operate independently!

The manufacturer recommends setting the factory settings when first turned on, but over time they need to be adjusted. For example, in summer in a hot climate you may need to increase the cooling power, and in winter - reduce it to avoid icing.

Optimal temperature conditions for a refrigerator Stinol

The manufacturer Stinol in the technical documentation indicates the following recommended values:

It is important to understand that the temperature in the refrigerator is distributed unevenly unevenly:

• 🥶 The coldest place is the door. Ideal for drinks, sauces, butter. on the shelves at the back wall (the evaporator is located there).
• 🌡️ The warmest place - door. Ideal for drinks, sauces, oils.
• ❄️ In the freezer, the temperature also varies: the bottom drawers are usually 1-2°C colder than the top ones.

If your Stinol equipped function Super Cool or Fast Freeze, use it 12-24 hours before loading a large amount of food (for example, before the holidays). This will help avoid overheating of the compressor.

How to regulate the temperature in Stinol refrigerators with a mechanical thermostat

Mechanical regulators in models Stinol STN 100, STN 167, STN 190 and similar ones are controlled by a rotary knob with a digital scale: Here's how to set them up correctly:

1. Find the regulator. It is usually located:
   • 🔹 Inside the refrigerator compartment on the right wall (for models with a top freezer).
   • 🔹 On the top panel above the door (for models with a bottom freezer, for example. STN 175).
2. Determine the current position. The numbers on the scale indicate not degreesand cooling power level:
   • 🔢 1–2 - minimum cooling (suitable for winter or cool rooms).
   • 🔢 3–4 —the optimal mode for most conditions.
   • 🔢 5–7 —maximum cooling (needed in summer or under high load).

Example setting for Stinol STN 167:

Summer, room temperature +28°C:
- Refrigerator compartment: position "5"
- Freezer: position "4" (if there is one regulator) or "3-4" (if there is a separate regulator)

- Wait 12 hours for the temperature to stabilize

- Check that there is no ice on the back wall

- Make sure that the compressor turns off (does not work constantly)

- Measure the temperature with a thermometer-->

⚠️ Attention: If, after setting the regulator to position "7", the refrigerator does not cool to the desired temperature, this may indicate data-i="136">or thermostat malfunction or leakage freon. Do not try to “unscrew” the handle further - this will lead to non-stop operation of the compressor and its overheating.

Setting the electronic thermostat in modern Stinol models

Refrigerators Stinol with electronic control (for example, STN RF 385, STN RF 420) are equipped with a display and touch buttons. The setting algorithm is different here:

1. Activate the control panel. On some models you need to press a button Menu or Set (depending on the series).
2. Select the adjustment zone:
   • 🧊 Button Fridge — refrigerator compartment.
   • ❄️ Button Freezer —freezer compartment.

Features of electronic models:

• 📊 Indication of the current temperature updated every 30 minutes. Do not be alarmed if the values ​​on the display do not change immediately after the change.
• ⚙️ The "Vacation" function (if available) puts the refrigerator into energy-saving mode (+10...+15°C). Activated by holding the button Vacation 3 seconds.
• 🔄 Auto-defrost in models with No Frost can temporarily increase the temperature to +8°C - this is normal.

In refrigerators with dual cooling system (two compressors), the settings of the freezer and refrigerator compartment are adjusted independently. For example, in Stinol STN RF 420 you can install +4°C in the main compartment and –20°C in the freezer at the same time.

Common mistakes when adjusting the temperature

Even experienced users sometimes make mistakes that lead to damage to products or breakdown of equipment. Here are the most common of them:

• ❌ Setting maximum cooling "just in case". This leads to:
  • Icing of the rear wall and products.
  • Increased energy consumption (up to +30%).
  • Accelerated wear compressor.
• ❌ Ignoring seasonal changes. In winter, in an unheated room (for example, in a country house), the refrigerator may become overcooled if the power is not reduced.
• ❌ Frequent changes to settings. The compressor takes 6–12 hours to stabilize the temperature. Constantly “twisting” the knob leads to failures.
• ❌ Storing hot products. An increase in the temperature inside the chamber forces the compressor to work without stopping.

Typical situation: the user sets the regulator to “7” because “it’s not cold enough in the freezer,” but at the same time:

• 🔌 The refrigerator is in a hot room (+30°C).
• 🚪 The door often opens (for example, in a family with children).
• 🍗 The freezer is loaded with a lot of warm food.

In this case, it is better not to increase the power, but to eliminate external factors: ventilate the room, reduce the frequency of opening the door, defrost the food before storing it.

⚠️ Attention: If, after adjustment, the temperature in the refrigerator compartment drops below +2°C, and ice appears on the back wall, immediately reduce the cooling power. Maintaining a temperature below 0°C for a long time leads to spoilage of fruits, vegetables and dairy products.

How to check whether the thermostat in a Stinol refrigerator is working

If the refrigerator does not respond to changes in settings (does not cool or, conversely, freezes), the first thing you need to do is check the thermostat. Here step-by-step diagnostics:

1. Disconnect the refrigerator from the mains and take out all the products.
2. Find the thermostat:
   • In mechanical models it is located behind the adjustment knob (you need to remove plastic cover).
   • In electronic cases, the sensor can be hidden under the rear panel (disassembly required).
3. Check the contacts:
   • 🔌 Disconnect the wires from the thermostat.
   • 🔍 Inspect for oxidation or breaks.

Set the multimeter in resistance test mode (200 Ohms).
At room temperature, a working thermostat shows 0 Ohm (contacts are closed).
When cooling (for example, apply ice), the resistance should increase to infinity.

Signs of a faulty thermostat:

• 🔴 The compressor works without stopping or does not turn on at all.
• 🔴 The temperature in the chamber does not correspond to the set values (for example, with “3” on the regulator in the refrigerator +10°C).
• 🔴 Clicks inside the housing when turning the knob (for mechanical models).

If the thermostat is faulty, it must be replaced. For models Stinol original parts are suitable K59-L1437 (mechanics) or WDF19 (electronics), but check the exact marking on the label on the thermostat itself.

Temperature adjustment in Stinol refrigerators with the No Frost system

Models Stinol with technology No Frost (for example, STN RF 385, STN RF 420) require a special approach to configuration. Here, cooling is carried out due to the circulation of cold air, and not through direct contact of the evaporator with the products. Features:

• 🌀 The temperature is distributed more evenly, but may fluctuate a little when the door is opened.
• ❄️ Auto defrost turns on every 8-12 hours (for 15-30 minutes). At this time, the temperature in the chamber can rise to +8...+10°C.
• ⚡ Energy consumption is higher by 10–15% compared to drip models.

Recommendations for setting:

1. Set the temperature of the refrigerator compartment to +4°C, freezer - to –18°C.
2. Do not load food close to the ventilation holes (usually located on the back wall).
3. Once every 6 months, clean the drainage hole (located under the drawers). fruits) from dust and debris.

In models with No Frost it is strictly forbidden to:

• 🚫 Set the regulator to maximum "on an ongoing basis" - this will lead to icing of the fan.
• 🚫 Store liquids in open containers - moisture disrupts the operation of the system.
• 🚫 Use sharp objects to remove ice (if it suddenly appears).

⚠️ Attention: If ice appears on the back wall of the refrigerator, this is a sign of a malfunction of the defrosting system (the heating element or sensor has burned out). Self-repair is unacceptable here - diagnostics are required at a service center. Stinol No Frost Ice has appeared on the back wall, this is a sign of a malfunction of the defrosting system (the heating element or sensor has burned out). Self-repair is unacceptable here - diagnostics are required at a service center.

What to do if the Stinol refrigerator does not hold the temperature

If after all manipulations with the regulator the temperature in the refrigerator remains unstable, check the following points:

If the refrigerator Stinol is new (up to 1 year), the malfunction may be associated with defective compressor or improper transportation. In this case, contact the store for a replacement under warranty. For models older than 5 years, replacement is most often required temperature regulator or start relay.

Before calling the technician, perform a simple check:

1. Disconnect the refrigerator from the mains for 24 hours (complete defrosting).
2. Turn it on again and set the medium settings (3–4 on the mechanical regulator or +5°C on electronic).
3. Check the temperature after 12 hours. If the problem remains, repair is required.
