If your refrigerator Samsung starts malfunctioning, do not rush to call a technician. Perhaps the problem lies in the thermostat, and you can fix it yourself, saving on repairs.

What does the thermostat look like in a Samsung refrigerator?

Thermoregulator (thermostat) in refrigerators Samsung is a small device with a plastic or metal case, to which 2-4 wires fit. Most often, it has a round temperature control knob (in mechanical models) or hidden under the control panel (in electronic ones).

Externally, the thermostat may resemble:

• 🔘 Cylindrical barrel with a protruding rod (in older models)
• 📱 Flat box with contacts (in modern refrigerators with No Frost)
• 🔧 Module with sensorsintegrated into the control board (in inverter models)

Mechanical thermostats usually have capillary tube - a thin copper tube that is attached to the evaporator. It is filled with refrigerant and reacts to temperature changes. In electronic models, instead of a tube, thermistors (resistance sensors) are used.

Where is the thermostat located in Samsung refrigerators of different series?

The location of the thermostat depends on type of cooling system and model refrigerator. Below we will look at the most common options.

1. Refrigerators with a drip system (without No Frost)

In models Samsung series RL (for example, RL34ECMS, RL38GCMS) and RB thermostat usually located inside the refrigerator compartment, next to the lighting lamp. It can be found:

• 🔦 Under the plastic cover on the top panel (right or left)
• 🔧 Behind the decorative trim attached to the back wall
• ⚙️ Next to the temperature control knob (if it is mechanical)

To get to the thermostat, sometimes it is enough to remove the lamp protective cover. In other cases, you will have to unscrew several screws and remove the top panel.

2 Refrigerators with the No. system. Frost

In models Samsung s No Frost (series RS, RF, RH), the thermostat is most often removed outside the chamber and can be located:

• 📍 In upper section behind the plastic panel (for example, in RS552NRUA)
• 📍 On rear wall the refrigerator, next to the compressor
• 📍 Inside electronic control unit (in models with a display)

In systems No Frost the thermostat is often replaced with temperature sensor (thermistor), which transmits signals to the control board. In this case, you need to look not for the thermostat itself, but connector with wirescoming from the sensor.

3. (freezer + refrigerator compartment)

In two-chamber models Samsung (for example, RT32K5930S8, RT43K6230) there can be twothermostats: one for the refrigerator compartment, the other for the freezer. Usually they are located:

• 🧊 B freezer — behind the back panel, next to the evaporator
• ❄️ B refrigerator compartment — under the top shelf or behind the control panel

If the refrigerator is equipped with one compressorthermostats can be connected in series. In models with two compressors each thermostat operates independently.

How to distinguish a thermostat from a temperature sensor?

A thermostat is a mechanical or electromechanical device with moving contacts that physically opens/closes a circuit. A temperature sensor (thermistor) is an electronic element that only. measures the temperature and transmits a signal to the board. Samsung refrigerators with No Frost often use sensors, and older models use thermostats.

⚠️ Attention: In refrigerators Samsung with inverter compressors (series BESPOKE, Family Hub), the thermostat can be integrated into the control board. Self-replacement in such models is not recommended - electronic flashing is required. unit.

Signs of a malfunctioning thermostat in a Samsung refrigerator

If the thermostat fails, the refrigerator starts to work incorrectly. Here are the main symptoms:

• ❄️ Refrigerator is not cooling or it freezes too weakly
• 🔥 The compressor runs without stopping (overheating)
• 💧 Ice forms on the back wall (in models without No Frost)
• 🔄 The temperature fluctuates (then too cold, then too warm)
• 🚨 An error appears on the display (for example, E1, E2 in electronic models)

If the refrigerator Samsung stopped freezing, but the light inside is on, the problem is most likely in the thermostat or compressor. If the light also does not work, check the power filter or fuse.

In Samsung refrigerators with the No Frost system If the thermostat (sensor) breaks down, error E1 or E2 often comes on. In drip models, the main symptom is that the compressor does not turn off or, on the contrary, does not turn on.

How. check the thermostat with a multimeter?

Before replacing the thermostat, you need to check it. To do this, you will need a multimeter (tester) and a screwdriver. Follow the instructions:

1. 🔌 Disconnect the refrigerator from the network.
2. 🔧 Remove the protective panel (depending on the model - top, rear or front).
3. 📍 Find the thermostat and disconnect the wires from it (take a photo of the connection diagram!).
4. 🔍 Ring the contacts with a multimeter in resistance test mode (Ω).

In a working thermostat at room temperature, the resistance between the contacts should be 0 Ohm (closed). If indicator ∞ (open) - the thermostat is faulty.

For a more accurate check:

1. Place the thermostat in cold water (with ice added).
2. After 2-3 minutes, check the resistance again.
3. If the contacts opened the thermostat is working. If not, replacement is required.

⚠️ Attention: In electronic models Samsung the thermostat can be replaced with a temperature sensor (thermistor). Its resistance is checked differently: at room temperature. (~25°C) it should be about 5-10 kOhm. When cooling, the resistance increases, when heating it decreases.

How to replace the thermostat in a Samsung refrigerator?

If the check shows that the thermostat is faulty, it needs to be replaced. To do this:

1. 🛒 Buy a new thermostat (suitable for your model Samsung).
2. 🔧 Disconnect the refrigerator from network and defrost (if required).
3. 🔨 Remove the panel, behind which the thermostat is located.
4. 📸 Take a photo of the wire connection diagram (so as not to mix it up during reassembly).
5. 🔄 Disconnect the old thermostat and install new.
6. 🔩 Connect the wires according to the diagram.
7. 🧪 Check the operation of the refrigerator (the compressor should turn on).

In models with No Frost there may be a temperature sensorinstead of a thermostat. Replacing it is more difficult - you need to carefully unsolder the old sensor and solder the new one without damaging the board.

If you are not confident in your abilities, it is better to contact to the technician. Incorrect replacement can lead to:

• ⚡ Short circuit (if the wires are mixed up)
• 🔥 Compressor breakdown (due to incorrect thermostat settings)
• 💸 Additional costs for repairs

Frequent errors when searching and replacing the thermostat

Many users make mistakes when trying to find or replace the thermostat. Here are the most common ones:

• 🔍 They confuse the thermostat with the compressor relay (they look similar, but perform different functions).
• 🔧 Do not disconnect the refrigerator from the network before work (risk of shock). electric shock!).
• 📸 Do not photograph the connection diagram and then confuse the wires.
• 🧊 Do not defrost refrigerator before replacing (ice prevents you from getting to the parts).
• 🛠️ Using the wrong thermostat (even if it looks similar, the parameters may differ).

Another common mistake is attempting to repair the thermostat. This is a mechanical (or electronic) device that cannot be repaired - only if it is broken. replacement.

⚠️ Attention: In refrigerators Samsung with electronic control (for example, Family Hub) after replacing the thermostat, you may need to reset the settings or reflash the board. Without this, the refrigerator may not turn on.
