How to adjust the thermostat of a Stinol refrigerator: instructions with photos and tips

The thermostat in the refrigerator Stinol is the key unit responsible for maintaining the set temperature. If it is not set correctly, food will either freeze or spoil faster due to insufficient cooling. In most cases, you can adjust the thermostat yourself without resorting to the services of a technician. But it is important to understand: models of Stinol different years of manufacture (for example, Stinol 100, Stinol 102, Stinol 110) may have differences in the design of the thermostat.

In this article you will find step-by-step instructions for mechanical and electronic thermostats, learn how to check the operation of the unit and what kind optimal temperatures install for the refrigerator and freezer compartments. We will also analyze typical adjustment errors that lead to compressor breakdowns or freon leaks.

Signs of incorrect thermostat operation

Before you start adjusting, make sure that The problem is with the thermostat. The following symptoms may indicate problems:

• 🔄 The compressor runs without stopping —this leads to icing of the rear wall of the refrigerator compartment and increased energy consumption.
• ❄️ Formation of a thick layer of ice in the freezer (more than 5 mm) or ice on food in the refrigerator compartment.
• 🌡️ The temperature does not correspond to the set one: for example, when installed on +5°C the thermometer shows +10°C or 0°C.
• 🔇 The refrigerator does not turn on after a power outage or defrosting.

If you notice at least one of these signs, try first adjust the thermostat. In 60% of cases, the problem is solved by correct configuration. However, if after adjustment the symptoms persist, the thermostat may be faulty and requires replacement.

⚠️ Attention: In refrigerators Stinol with a system No Frost (for example, models Stinol NF 330), the thermostat controls not only the temperature, but also fan operation. Incorrect settings can lead to freezing of the air ducts.

Optimal temperatures for the Stinol refrigerator

The manufacturer recommends maintaining the following temperature conditions:

Use external thermometer to check the temperature (for example, for aquariums). Place it in the center of the refrigerator for 12 hours. If the readings differ from the set values by more than 2°C, adjustment is required.

In Stinol refrigerators with a mechanical thermostat (models before 2010), the adjustment scale often does not have a graduation in °C, but is indicated by numbers from 1 to 7. Here 1 is the warmest setting, 7 is the coldest.

Adjusting the mechanical thermostat

Mechanical thermostats were installed on most models Stinol until 2015 (for example, Stinol 101, Stinol 103). The adjustment is carried out using a rotary knob located inside the refrigerator compartment or on the top panel.

Make sure that the refrigerator is not in defrost mode|

Disable the "Super Freeze" function (if available)|

Check that the door is tightly closed|

Let the refrigerator run for 2-3 hours after changing the settings-->

Step-by-step instructions:

1. Find the thermostat knob. In models Stinol it is usually located on the right inside the refrigerator compartment or on the top panel (under the logo).
2. Turn the knob 1 division increasing (clockwise) or decreasing (counterclockwise). One division ≈ 2–3°C.
3. Wait 6–8 hours until the temperature stabilizes. Use a thermometer for control.
4. If necessary, repeat the adjustment, but do not change the position of the knob by more than 2 divisions at a time..

If after adjustment the compressor turns off too rarely (once every 1-2 hours), try reduce the value by 0.5–1 division. In models with a freezer compartment, a separate thermostat knob may be located inside the freezer (for example, in Stinol 107).

⚠️ Attention: In refrigerators Stinol with two compressors (for example, Stinol 205thermostats are adjusted independently! Changing the settings of the refrigerator compartment does not affect the freezer.

What to do if the thermostat knob does not turn?

If the knob is locked, the protection mechanism against accidental changing of the settings may have worked. Try pressing it slightly before turning it. Stinol 116 and Stinol 120 the handle is fixed with a spring mechanism - pull it towards you and turn it at the same time.

Setting up an electronic thermostat

Electronic thermostats are installed on modern models Stinol (for example, Stinol RTM 20, Stinol RTM 26). They allow you to set the temperature with an accuracy of 1°C and are often equipped with a display.

Instructions for electronic control:

1. Press the button Temp (or Set) on the panel control. In models with a touch screen, hold your finger on the thermometer icon for 3 seconds.
2. Use the +/– (or ▲/▼) buttons to set the desired temperature for the refrigerator compartment. Confirm the selection with the button OK.
3. For the freezer, repeat the steps. by first pressing the button Freezer (or the snowflake icon).
4. Wait for a signal (sound or light) confirming that the settings are saved.

In some models (for example, Stinol RTM 18) after changing the temperature, a timer is displayed on the display --:--. This means that the refrigerator goes into stabilization mode. Do not open the door for 1-2 hours!

Checking the functionality of the thermostat

If the adjustment does not produce results, the thermostat may be faulty. You can check it without special tools:

• 🔧 Shutdown test: Turn the thermostat knob to the minimum value (or turn off the power). If it continues to work, the thermostat. faulty.
• ❄️ Freeze test: Set maximum cooling. After 2 hours, check the temperature: if it has not dropped below +2°C, the thermostat does not transmit a signal to the compressor.
• 📊 Check with a multimeter: To do this, you will need access to the thermostat contacts. At room temperature, there should be resistance between the terminals 3 and 4 there must be resistance 0 Ohm (closed).

In models Stinol with electronic control (for example, Stinol RTM 32), a thermostat malfunction is often accompanied by an error code on the display:

• E1 — problem with the fridge compartment temperature sensor;
• E2 — malfunction of the freezer sensor;
• E4 — open circuit of the thermostat.

⚠️ Attention: In refrigerators Stinol with an inverter compressor (models after 2018), replacing the thermostat requires reflashing the control unit. Do not try to do this yourself!

Typical errors when adjusting

Incorrect actions when adjusting the thermostat can lead to compressor failure or refrigerant leakage. Here are the most common mistakes:

• 🔄 Frequent changes of settings. The compressor needs time (6-12 hours) to stabilize the temperature. Constant changes lead to overheating of the motor.
• ❄️ Ignore defrosting. Ice on the evaporator interferes with the correct operation of the thermostat. Defrost the refrigerator at least once every 6 months (for models without No Frost).
• 🔌 Adjustment with the door open. The thermostat reacts to the temperature inside the chamber. An open door distorts the readings.
• 🛠️ Independent repair without diagnostics. If the thermostat is faulty, it needs to be replaced, and not “repaired” with a soldering iron.

In models Stinol with a system No Frost (for example, Stinol NF 440) error is turning off the fan manually. This leads to freezing of the air ducts and failure of the defrosting heating element.

When to contact a technician

Not all problems with the thermostat can be solved on your own. Calling a technician is necessary in the following cases:

• 🔧 The thermostat does not respond to adjustment (the compressor does not turn on / does not turns off).
• 💥 Errors appear on the display E3, E5 or F1 (indicate a malfunction of the electronic unit).
• ⚡ The refrigerator emits an electric current when touching the body (the thermostat insulation may be damaged).
• 🔥 The compressor overheats (the housing is hot, a burning smell is heard).

The cost of replacing the thermostat at the service center varies from 1,500 to 3,500 rubles (depending on the model). For refrigerators Stinol with electronic control, additional diagnostics of the board may be required. (from 1,000 rubles).

If your refrigerator is under warranty, do not disassemble it yourself this will void the warranty. In models Stinol warranty for the thermostat is 2-3 years (check in the product passport).

FAQ: Frequently asked questions about the Stinol thermostat

Is it possible to adjust the thermostat when the refrigerator is turned on?

Yes, but only for mechanical thermostats. In electronic models (Stinol RTM series), it is better to carry out the adjustment with the power off to avoid firmware failure.

Why did the refrigerator become more noisy after adjusting the thermostat?

This may be due to an increase in the load on the compressor. If the noise does not disappear within a day, return the settings to their original position and check the compressor fastening (the bolts may be loose).

How to reset the thermostat settings to factory settings?

In mechanical models, turn the knob to position 3 (average value). In electronic ones - hold the button Set 10 seconds or unplug the refrigerator for 5 minutes.

What to do if the thermostat rotates, but the temperature does not change?

Most likely it is broken bellows (sensitive element of the thermostat) or the contacts have oxidized. The unit needs to be replaced.

Is it possible to install a thermostat from another Stinol model?

Only if the models are identical in technical characteristics. For example, a thermostat from Stinol 102 suitable for Stinol 104, but not for Stinol RTM 20 (different types of control).
