Where the thermostat is located in the Atlant refrigerator: search by model and replacement instructions

The thermostat (or thermostat) is a key element of the refrigerator Atlant, responsible for maintaining the set temperature. When it fails, the compressor either works without stopping or does not turn on at all, which leads to food spoilage or freezing. But before changing the part, you need to know exactly where the thermostat is located in your model - its location depends on the year of manufacture, type of control (mechanical/electronic) and the design of the refrigeration chamber.

Many users mistakenly look for the thermostat inside the freezer compartment or behind the back wall, wasting time on disassembly. In fact, in most models Atlant (for example, MHM 1705, MX 2824, XM 4021) it is hidden in a plastic case next to the temperature control knob —but there are exceptions. In this article we will analyze all the location options, provide photos and diagrams, and also tell you how to check and replace the thermostat yourself without the risk of damaging the refrigerator.

⚠️ Attention: If your refrigerator Atlant was produced after 2018 and is equipped with an electronic display (series Nova Frost, Smart), the thermostat can be integrated into the control board. In this case, replacement requires special skills - it is better to contact a service center.

1. What does the thermostat look like in the Atlant refrigerator?

The thermostat in the models Atlant is a small device of a cylindrical or rectangular shape with capillary tubewhich goes deep into the fridge compartment. Externally, it looks like a plastic box with contacts for connecting wires and a rod for attaching the adjustment knob. The body is usually marked (for example, K-59, TAM-133, Danfoss 077B6).

Main visual features:

• 🔹 Capillary tube —a thin metal tube going from the thermostat to the evaporator (sometimes it is confused with the drainage system).
• 🔹 Terminals for wires —usually 3-4 contacts for connecting to the compressor and lighting lamp.
• 🔹 Adjustment knob —a plastic disk or lever that is attached to the thermostat rod (in mechanical models).
• 🔹 Marking —inscriptions with the thermostat model (for example, Atlant K-59-L2).

In electronic refrigerators, the thermostat can be replaced temperature sensor. with a thermistor, which transmits signals to the control board. In this case, outwardly you will see only a small plastic case with wires, without a capillary tube.

2. Is there a thermostat in Atlant refrigerators of different series?

The location of the thermostat depends on model and year of manufacture. Below we have provided diagrams for the most common series. If your model is not in the list, focus on the type of control (mechanical/electronic) and the design of the chamber.

2.1. Mechanical models (single-chamber and double-chamber)

In most mechanical refrigerators Atlant the thermostat is located inside the fridge compartment, behind the plastic panel next to the temperature control knob. To get to it, just remove the handle and unscrew the fastening screws. panels.

Examples of models: MHM 1705, MX 2824, XM 4021, MX 2831.

2.2. Electronic models (with display)

In electronically controlled refrigerators (series Nova Frost, Smart, NF), the thermostat is often replaced temperature sensor, which transmits data on the board. The board itself can be located:

• 🔹 Behind the top cover fridge compartment (for example, Atlant NF 3204).
• 🔹 Inside the freezer compartment (models with No Frost).
• 🔹 On the back wall next to the compressor (rarely).

⚠️ Attention: In electronic models, replacing the thermostat requires reflashing the control board. If you are not confident in your skills, it is better to call a technician.

2.3. Models with the No Frost system

In refrigerators Atlant s No Frost (for example, Atlant NF 3424, NF 3206) the thermostat can be:

• 🔹 Inside freezer compartment, behind the back panel (next to the fan).
• 🔹 On control board (in electronic versions).
• 🔹 In refrigerator compartment, but hidden under air duct.

To get to the thermostat in No Frostyou will have to remove the inner rear panel of the freezer. Be careful not to damage the fan and defrost heating element!

3. How to remove the thermostat: step-by-step instructions

If you find the thermostat, but do not know how to remove it, follow these instructions. Before starting work, be sure to unplug the refrigerator!

Unplug the refrigerator from the outlet|Remove all the food from the chamber|Remove the temperature control knob|Prepare a screwdriver and pliers|Take a photo of the wire connection-->

Step 1: Removing the handle and decorative panel

1. Pull gently temperature control knob to yourself - it should be removed without effort (sometimes it is secured with a latch).

2. Under the handle you will see plastic panel or a metal plate secured with self-tapping screws. Unscrew them (usually 2-3). self-tapping screw).

3. Remove the panel - the thermostat is hidden behind it.

Step 2: Disconnecting the capillary tube and wires

1. data-i="172">from the evaporator. It is attached either to a clamp or soldered. capillary tube from the evaporator. It is attached either to a clamp or soldered. Do not bend the tube! - this can lead to refrigerant leakage.

2. Take a photo or write down the wiring diagram (usually there are 3-4 of them: from the compressor, lamp and ground).

3. Carefully remove the terminals from the thermostat contacts. If the wires are soldered, you will have to bite them off and then restore the connection.

Step 3: Removing the thermostat

1. Unscrew the mounting screws or nuts holding the thermostat in place.

2. Remove the device. If the capillary tube is fixed inside the chamber, carefully pull it out without damaging the insulation.

⚠️ Attention: In some models Atlant (for example, MHM 1635) the thermostat is attached to the evaporator using clamp. Do not lose it during dismantling!

4. How to check the thermostat for functionality?

Before buying a new thermostat, make sure that the old one is really broken. For this you will need multimeter (tester).

Method 1: Checking resistance

1. Switch the multimeter to resistance measurement mode (Ω).

2. Connect the probes to the contacts of the thermostat (usually these are terminals 3 and 4 - see the diagram on the case).

3. At room temperature, the resistance should be 0 Ohm (closed). If the device shows infinity the thermostat is faulty.

Method 2: Checking in the cold

1. Place the thermostat in the freezer for 10-15 minutes (or wrap it in ice).

2. After cooling, measure the resistance again. If the thermostat is working, the contacts should open (resistance → ∞).

3. Take out the thermostat and let it warm up. The contacts should close again (resistance → 0).

If the thermostat does not respond to temperature changes, it needs to be replaced.

What to do if the multimeter no?

If you don’t have a tester at hand, you can check the thermostat “by ear”:

1. Unplug the refrigerator.

2. Remove the thermostat, but do not disconnect the wires.

3. "0" to the "Max" position.

4. Listen: if you hear a click inside the thermostat, it is working. If there is silence, it is most likely broken.

5. Which thermostat should you buy as a replacement?

Thermostats for refrigerators Atlant differ in model, capillary tube length and temperature range. You can’t use the first one you get! - this can lead to improper operation of the compressor.

Here is the correspondence of the models thermostats and refrigerators:

• 🔹 Atlant MKhM 1705, MH 2824 → K-59-L2 or TAM-133-1M.
• 🔹 Atlant XM 4021, XM 4026 → Danfoss 077B6.
• 🔹 Atlant NF 3204 (No Frost) → Thermistor 15K (sensor for electronic models).
• 🔹 Atlant MX 2831 → K-59-L2-21 (with an extended capillary tube).

Where to buy:

• 🛒 Official service centers Atlant - guarantee of an original part.
• 🛒 Online stores (for example, 220-Volt, All-ZIP) - check compatibility by refrigerator model.
• 🛒 Stores of spare parts for household appliances —sometimes there are used thermostats in good condition.

⚠️ Attention: When purchasing, check the length of the capillary tube! If it is shorter than the original one, the thermostat will not reach the evaporator, and the refrigerator will not regulate the temperature correctly.

6. Replacing the thermostat: step-by-step instructions

If you are convinced that the thermostat is faulty and bought a new one, proceed to replacement. Important: perform all work with the power off!

Step 1: Installing a new thermostat

1. Carefully insert the new thermostat in place of the old one, securing it with screws or nuts.

2. Connect the capillary tube to the evaporator. bends and does not touch the walls of the chamber.

Step 2: Connecting the wires

1. Connect the wires according to the diagram that you photographed earlier. Usually:

• 🔹 Terminal 3 — wire from the compressor.
• 🔹 Terminal 4 —wire from the lighting lamp.
• 🔹 Terminal 6 —grounding (if any).

2 If the wires were bitten off, use soldering iron or terminal blocks to restore the connection.

Step 3: Checking operation

1 Set the adjustment knob to the middle position. (usually 3-4).

2. Connect the refrigerator to the network.

3. Listen: the compressor should start in 5-10 minutes. If it runs without stopping or does not turn on, check the wire connections.

⚠️ Attention: After replacing the thermostat, do not load the refrigerator with food immediately! Let it run idle for 2-3 hours to ensure stable operation.

7. Frequent errors when replacing the thermostat.

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. That's what you can't do:

• 🚫 Use a thermostat from a different model - even if it looks similar, the temperature range may not match.
• 🚫 Kink the capillary tube —this breaks its tightness and leads to incorrect readings.
• 🚫 Connect the wires at random —an incorrect circuit can burn the compressor or control board.
• 🚫 Cover the thermostat with thermal insulation —it must be in contact with the air of the chamber.
• 🚫 Ignore checking with a multimeter —sometimes the problem is not in the thermostat, but in the wiring.

If after replacement the refrigerator is unstable (for example, freezes too much or does not turn off), check:

• 🔹 Correct connection of the capillary tube.
• 🔹 The tightness of the door seal.
• 🔹 Thermostat settings (the handle must be in position 2-4).

FAQ: Frequently asked questions about the thermostat in the Atlant refrigerator

🔍 How to understand that the thermostat is broken and not the compressor?

If the compressor does not turn on at all, the problem may be in both units. To check:

1. Disconnect the refrigerator from the refrigerator. network.
2. Remove the thermostat and short-circuit the wires going to the compressor (usually terminals 3 and 2).
3. Turn on the refrigerator. If the compressor works, the thermostat is to blame. If not, the problem is in the compressor or start relay.

🔍 Is it possible to repair the thermostat or just replace it?

Thermostats in refrigerators Atlant are sealed devices with a gas filler. If it fails, the only option is replacement - oxidized contacts, which can be cleaned with sandpaper.
