How to properly remove the thermostat from an Atlant refrigerator: instructions with photos and tips

Removing the thermostat (or thermostat) from the refrigerator Atlant is a task that owners face in the event of breakdowns such as constant operation of the compressor, lack of cooling, or, conversely, excessive icing. In most cases, the problem lies precisely in this unit, and replacing it is cheaper than calling a technician. However, improper dismantling can lead to damage to the capillary tube, freon leakage or short circuit.

In this article we will analyze the process step by step: from preparing tools to checking the functionality of the new thermostat. We will place special emphasis on models Atlant with mechanical control (MXM, MX, XM series), since electronic systems require a different approach. If your refrigerator was manufactured after 2018, check the type of thermostat by the marking on the back wall - new versions may use sensors with a digital protocol..

Before you begin, answer two questions:

  1. Do you have experience working with electrical appliances? If not, it’s better to invite a specialist.
  2. Is the warranty on the refrigerator still valid? Self-repair will invalidate it.

1. Signs of a thermostat malfunction: when it needs to be removed

The thermostat in refrigerators Atlant is responsible for turning the compressor on/off depending on the temperature in the chamber. Its breakdown manifests itself clearly, but the symptoms can be confused with other malfunctions (for example, a freon leak or a failure of the start relay). Let's consider key signswhich will point specifically to the thermostat:

The compressor works without stopping - if the motor does not turn off even when the minimum temperature is reached, the thermostat is “stuck” in the “on” position. This leads to freezing of food and increased energy consumption.

❄️ It is too cold in the chamber or, conversely, warm —the thermostat may give incorrect signals, causing the temperature to jump from -20°C to +10°C. Check whether the food in the freezer compartment is covered with a thick layer of ice, and in the main compartment, whether water has appeared on the shelves.

🔌 The refrigerator does not turn on at all - if you do not hear a click (closing contacts) when you turn the thermostat knob, that is the problem. But first, check the outlet and power cord!

💡 The light inside is on and the motor is silent is an indirect sign of an open circuit in the thermostat circuit. Normally, when the thermostat is turned on for maximum cooling, the compressor should start within 1-2 minutes.

If you observe at least one of these symptoms, first rule out other causes:

  • 🔌 Check the voltage in the socket — perhaps there is a problem in the network.
  • ❄️ Defrost the refrigerator - sometimes the ice “coat” blocks the sensors.
  • 🔧 Inspect the start relay - it is located next to the compressor and often fails.

2. Preparation for dismantling: tools and safety measures

Before removing the thermostat, be sure to unplug the refrigerator wait until it is completely defrosted (if there was icing). Working with wet live parts is dangerous! Also prepare the following tools:

  • ⚒️ Phillips and flathead screwdrivers —to unscrew the screws and dismantle the panel.
  • 🔧 Pliers or pliers —may be needed to remove the fixing brackets.
  • 📸 Smartphone or camera —to photograph the location of the wires before disconnecting.
  • 🧲 Magnet or marker —for marking the wires (if they are the same color).
  • 🧤 Rubber gloves - protection against accidental electric shock (although the voltage is turned off, capacitors can retain charge).

⚠️ Attention: If your refrigerator Atlant is equipped with a system No Frost, dismantling the thermostat can require removal of the freezer interior panel. In this case, additionally prepare:

  • 🔨 10 mm socket wrench —for unscrewing the evaporator fasteners.
  • 🧴 Silicone grease —for processing the seals after assembly.

Also note that in models Atlant MHM-1705, MHM-1806, XM-4026 the thermostat is located inside the refrigerator compartment, under a plastic cover. In two-chamber refrigerators (for example MX-2824, MX-2831) it can be located outside, on the back wall, next to the compressor.

3. Where is the thermostat located in refrigerators Atlant: diagrams and photos

The location of the thermostat depends on the model and year of manufacture. In most cases, it can be found in one of three places:

  1. Inside the refrigeration chamber - under the plastic casing, next to the light bulb. Typically for single-chamber models (MHM-1705, MHM-1806) and old two-chamber (XM-4026).
  2. On the back wall of the refrigerator —in a plastic box next to the compressor. More often found in new two-chamber models (MX-2824, MX-2831).
  3. In the freezer —under the top panel, if the refrigerator has a system No Frost (Atlant XM 6025-080 and the like).

Below is a table with the approximate location of the thermostat for popular models:

Refrigerator model Thermostat type Location Dismantling features
Atlant MXM-1705 Mechanical (K-59, TAM-133) Inside the refrigeration chamber, under cover It is necessary to remove the temperature control knob
Atlant MX-2824 Mechanical (TAM-125) On the back wall, in a box with a relay Access after removing the back cover
Atlant XM-4026 Mechanical (K-56) Inside the camera, under the top panel You will have to disconnect the capillary tube
Atlant XM 6025-080 (No Frost) Electronic sensor In the freezer, behind the panel Requires disassembly of the inner box

📌 How to accurately determine the location?

  1. Look on temperature adjustment knob - if it is inside the chamber, the thermostat is there.
  2. If there is no knob, inspect rear wall - look for a plastic box with wires going to the compressor.
  3. In models with No Frost the thermostat can be hidden under the top panel of the freezer.
What to do if you can’t find the thermostat?

If visual inspection does not help, use a multimeter in dial mode:

1. Unplug the refrigerator.

2. Remove the back cover (if the thermostat is not inside the chamber).

3. Find the wires coming from the temperature control knob to the compressor - they lead to the thermostat.

4. Ring the circuit: when you turn the knob to maximum, you should hear a sound signal (closing contacts).

4. Step-by-step instructions: how to remove the thermostat from the refrigerator Atlant

Let's consider a universal algorithm for mechanical thermostats (the most common option). If you have an electronic sensor, the process will be more complicated, and we recommend contacting a specialist.

🔧 Step 1: Disconnection and defrosting

  • Unplug the refrigerator from the socket.
  • Wait for complete defrosting (8-12 hours).
  • Remove all products and shelves that may interfere with access.

🔧 Step 2: Removing the protective panel

  • If the thermostat is inside the chamber:
    • Remove the temperature control knob (pull it towards you or pry it with a screwdriver).
    • Unscrew the screws securing the plastic cover (usually 2-4 pieces).
  • If the thermostat is on the back:
    • Unscrew the back cover of the refrigerator (screws around the perimeter).
    • Find a plastic box with wires - this is a block thermostat.

🔧 Step 3: Disconnecting the wires

  • Take a photo of the location of the wires or mark them with a marker.
  • Carefully remove the terminals from the thermostat contacts (a flathead screwdriver may be needed).
  • If the wires are soldered, use a soldering iron (but in Atlant detachable terminals are usually used).

⚠️ Attention: In some models Atlant the thermostat is connected to capillary tube (thin copper tube going to evaporator). Do not bend or damage it - this will lead to freon leakage and expensive repairs!

🔧 Step 4: Removing the thermostat

  • Unscrew the nuts or self-tapping screws securing the thermostat to the body.
  • If there is a fixing bracket, pry it off with a screwdriver.
  • Carefully pull out the thermostat along with the capillary tube (if any).

🔧 Step 5: Checking functionality (optional)

  • Test the thermostat with a multimeter:
    • Set the knob to MAX (maximum cooling) - the contacts should close (resistance ~0 Ohm).
    • Turn the knob to MIN — the contacts open (resistance → ∞).
  • If there is no reaction, the thermostat is faulty.

5. Typical mistakes when removing a thermostat and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns. Here are the most common of them and ways to prevent them:

  • 🔌 Operation under voltage - never check the thermostat without turning off the refrigerator! Even when turned off, capacitors can retain a charge.
  • 🔧 Loss of wires —if you do not mark or photograph the connection diagram, you can mix up the contacts during reassembly.
  • ❄️ Damage to the capillary tube —its bend or break will lead to freon leak. Hold the tube straight and do not apply force.
  • 🔨 Too much force when unscrewing - plastic fasteners are Atlant fragile. Use a screwdriver with the correct blade size.
  • 🧲 Ignoring checking the new thermostat —before installation, make sure that the new regulator is working (call it).

⚠️ Attention: If after replacing the thermostat refrigerator Atlant still does not turn on, check:

  • The correct connection of the wires (especially phase and neutral).
  • The integrity of the capillary tube (if it is damaged, refilling will be required freon).
  • Compressor performance (if the motor is faulty, the thermostat will not be able to start it).

💡 Tip: If you doubt your abilities, take a photo of each stage of disassembly and send the photo to the technician for consultation. This will save time and money on correcting errors.

6. How to connect a new thermostat: diagram and nuances

Installation of a new thermostat is done in the reverse order, but there are several key pointsthat need to be taken into account:

🔌 Wire connection diagram (typical for Atlant):

  • Terminal 1 (or 3) —phase wire (usually brown or red).
  • Terminal 2 —neutral wire (blue or black).
  • Terminal 4 — wire to the compressor (yellow, orange or white).
  • Terminal 6 —wire to the light bulb (if any).

📌 Step-by-step installation:

  1. Connect the capillary tube to the new thermostat (if it was disconnected). Secure it in the same position so as not to bend it.
  2. Connect the wires according to the diagram or your markings.
  3. Fix the thermostat in place (screws or nuts).
  4. Reinstall the protective panel and adjustment knob.
  5. Connect the refrigerator to the network and check the operation.

⚠️ Attention: In models Atlant with electronic control (Atlant XM 6025-080 and newer), the thermostat may be part of the control board. In this case. replacement requires soldering or programming - do not risk doing it yourself!

🔧 Check after installation:

  • Turn the thermostat knob to MAX —the compressor should start within 1-2 minutes.
  • After 10-15 minutes, check whether the freezer is getting cold.
  • If the refrigerator does not turn on, turn it off and check the wire connections.
What to do if the new thermostat does not work?

Possible reasons:

1. Wrong connection of the wires —recheck the circuit.

2. Faulty new thermostat —check it with a multimeter.

3. Problems with the compressor —if the motor does not hum when turned on, the starter may have burned out relay.

4. Freon leak —if the capillary tube was damaged during dismantling, refilling will be required.

7. Where to buy a thermostat for a refrigerator Atlant and how to choose the right one

Thermostats for Atlant are sold in spare parts stores for household appliances, in markets or in online stores (for example, AliExpress, Yandex MarketThe main thing is to choose exact modelas even visually similar ones). thermostats may have different characteristics.
