How to increase the temperature in the Atlant refrigerator: adjustment, setup and repair

Has your refrigerator Atlant turned into an arctic warehouse, and the food is covered with an ice crust? Or, on the contrary, does the freezer function like a refrigerator, but food spoils in the main compartment? The problem of too low a temperature is more common than it seems - and it is solved without calling a technician in 80% of cases. In this article we will analyze all ways to make the Atlant refrigerator warmerfrom basic thermostat adjustment to fault diagnosis.

It is important to understand: “warmer” does not mean “above +10°C”. We are talking about returning to standard values (+2...+5°C in the refrigerator and −18...−24°C in the freezer). We will not advise “just turning the knob to maximum” - this will lead to food spoilage. Instead, you will learn how to fine-tune the climate in the chambers, test sensors and eliminate typical failures in models Atlant (including MHM-1708, MX-2824, XM-4026 and others).

Spoiler: in 60% of cases the problem lies in incorrect settings or contamination of the system. The remaining 40% is divided between thermostat wear, freon leaks and electronics failures. Let's start with the simplest - and gradually reach the "heavy artillery".

1. Checking the current temperature: how to measure correctly

Before adjusting anything, you need to understand how much the refrigerator freezes. The built-in thermometer (if there is one) often lies by 2-3 degrees, and in budget models Atlant it may not be there at all. Here's how to measure the temperature accurately:

• 📏 Use alcohol thermometer (mercury is dangerous!). Place it in a glass of water and place it on the middle shelf of the refrigerator for 12 hours.
• ⏱️ Suitable for the freezer infrared thermometer (gun) - point it at the wall of the chamber (not at the food!).
• 📱 Alternative - wireless sensor (for example, Xiaomi Mijia) with notifications about exceeding normal limits.

Normal indicators for Atlant:

If the refrigerator compartment is below +2°C, and in freezer colder than −24°C - this is already frostbite, requiring intervention. Exception: "Super Freeze" or "Vacation" modes, which must be turned off manually (more on this below).

2. Temperature control with a mechanical thermostat

Most models Atlant (for example, MHM-1708, MX-2821) are equipped with mechanical thermostat a round knob with numbers from 1 to 7 (less often up to 9). Here's how to use it:

1. 🔍 Find the regulator - it is usually located inside the refrigerator compartment on the right wall or on top under the lamp.
2. 🔄 Turn the knob to one division counterclockwise (for example, from 5 to 4).
3. ⏳ Wait 6–8 hours (stabilization time temperature).
4. 📊 Re-measure the temperature. If it’s still cold, turn it one more division.

Important nuances:

• ❄️ The numbers on the handle are not degrees, and conditional positions. “1” is the warmest, “7” is the coldest.
• ⚠️ In models with with one compressor (for example Atlant MXM-1635), the regulator controls both chambers. In two-compressor (for example Atlant MXM-2832) there are separate handles for the refrigerator and freezer compartments.
• 🔋 If after adjustment the compressor does not turn off for more than 20 minutes, the thermostat is faulty (read section 5).

3. Disabling special modes

Many owners Atlant forget that their refrigerator can operate in enhanced modeswhich artificially lower the temperature. Check:

• ❄️ Super Freeze mode (Super Freeze) - activated by the button with the snowflake symbol. It turns off the same way. In some models (Atlant MHM-2824) it turns off automatically after 24 hours.
• 🏝️ Vacation mode (Holiday) - maintains +12…+15°C in the refrigerator compartment with a long absence. It can be turned off by a button with an image of a palm tree or the inscription HOLIDAY.
• 🔄 Quick Cooling mode (Fast Cool) - temporarily reduces the temperature for fast freezing. It turns off automatically after 6–12 hours.

How to check if the mode is on?

1. Inspect the control panel (usually on top of the door).
2. If the snowflake indicator is on 🏔️ or palm trees 🏝️ - the mode is active.
3. Press the corresponding button (you may need to hold it for 3-5 seconds).

What to do if the button does not respond?

If the mode indicator is on, but the button does not turn it off, reset the refrigerator to factory settings. To do this, unplug it for 10 minutes, then turn it on again. If the problem remains, the control board is faulty (diagnostics required).

4. Checking the seal and tightness

If the refrigerator Atlant works without stopping, but the temperature is still too low, worn sealmay be to blame. Warm air penetrates through the cracks, and the compressor is forced to freeze harder to compensate for the heat gain. How to diagnose:

• 🔦 Visual inspection: the seal must be solid, without cracks or peeling. Check the corners - that's where it wears out first.
• 📄 Test with paper: close the door, holding a sheet of paper between the seal and the body. If it falls out or is easily pulled out, the seal is broken.
• 💡 Checking with a lamp: in a dark room, shine a flashlight inside a closed refrigerator. If light is visible from outside, there are cracks.

How to restore the tightness:

1. Cleaning: wash the seal with warm water and soap, remove grease and dirt. Dry.
2. Lubricant: apply a thin layer silicone lubricants (not Vaseline!) on the rubber for elasticity.
3. Heating: if the seal is deformed, heat it with a hairdryer (temperature 50–60°C) and shape it by pressing the door.
4. Replacement: if the seal is cracked, buy a new one (article for Atlant usually starts with 6000- or 6001-).

⚠️ Attention: If the seal is covered with mold, it needs to be replaced. Mold not only spoils the seal, but is also dangerous to health. Cleaning with bleach will give a temporary effect.

5. Diagnostics of the thermostat and temperature sensors

If adjusting the thermostat did not help, and the seal is in order - the problem may be in faulty thermostat or sensors. Models Atlant use two types of systems:

• 🔘 Mechanical thermostat (for example, K-59 or TAM-133) - in budget models (MHM-1708, MX-2821).
• 📱 Electronic control unit with sensors - in modern refrigerators (XM-6025, MXM-2832).

Signs of a thermostat malfunction:

• The compressor is running continuously (does not turn off for more than 30 minutes).
• The temperature in the chambers does not correspond to the position of the handle (for example, on "2" it freezes like on "7").
• Refrigerator does not turn on after defrosting.
• Audible relay clicks, but the compressor does not start.

How to check the thermostat with a multimeter:

1. Disconnect the refrigerator from network.
2. Remove the thermostat protective casing (usually it is secured with 2-3 screws).
3. Disconnect the wires from the thermostat (take a photo of their location!).
4. Switch the multimeter to resistance test mode (200 Ohms).
5. At room temperature, the resistance between terminals 3 and 4 should be 0 Ohm (closed). If it shows "1" (open), the thermostat is faulty.

For electronic models:

• Check temperature sensor (usually located on the back wall of the chamber). Its resistance at +20°C should be about 5–7 kOhm.
• If the sensor “lies”, the control unit receives incorrect data and forces the compressor freezes more strongly.

⚠️ Attention: In refrigerators Atlant with a system No Frost a faulty defrosting sensor can lead to icing of the evaporator and freezing. If ice accumulates in the freezer, check the sensor and defrosting heating element.

6. Problems with the compressor and refrigerant

If the refrigerator Atlant freezes too much, but the compressor works intermittently (for example, it turns on for 5 minutes and turns off for 30 seconds), the problem may be:

• 🔧 Compressor wear —it cannot maintain stable freon pressure.
• ❄️ Refrigerant leak —freon leaks through microcracks in the tubes.
• 🔌 Malfunctions of the starting relay —the compressor turns on jerkily.

How to diagnose:

• The compressor heats up, but does not freeze → freon leak or capillary blockage tubes.
• The compressor does not turn on, but a hum is heard → the starting relay is faulty.
• The compressor works, but the refrigerator does not turn off → compressor wear or malfunction thermostat.

What you can do yourself:

1. Check relay: turn off the refrigerator, remove the relay (black box on the compressor) and shake it. If you hear a knock, the relay is faulty.
2. Clean the condenser (grid at the back of the refrigerator) for dust - this will improve heat transfer.
3. Check the voltage in the socket - if it is below 200V, the compressor may work unstably.

⚠️ Attention: Freon leakage is dangerous to health (if you inhale vapors). If you suspect a leak (oil stains on the tubes, lack of cold when the compressor is running), do not turn on the refrigerator and call a technician.

7. When to call a specialist: signs of serious malfunctions

Contact a specialist if:

• 🔧 The refrigerator not turns off more than a day, and the temperature continues to drop.
• ❄️ In the freezer compartment ice is growing (thickness is more than 5 mm) despite the mode No Frost.
• 💥 Heard popping or hissing — a sign of a freon leak.
• 🔌 The display lights up error (for example, E1, F2 —see the instructions for the model).
• 🔥 Compressor gets very hot (hotter than usual).

FAQ: Frequently asked questions about temperature control in Atlant

Why does the freezer compartment work in the Atlant refrigerator, but the refrigerator compartment does not?

This is a typical problem for models with one compressor (for example, MHM-1708). Reasons:

• Clogged capillary tube (refrigerant does not enter the refrigeration chamber).
• Malfunction magnetic valve (in models with No Frost).
• Freon leak in the refrigeration chamber circuit.

Solution: diagnostics by a technician is required. You can independently check whether the fan is blocked (in models with No Frost) products.

How to reset the Atlant refrigerator to factory settings?

The method depends on the model:

• For mechanical models: disconnect from the network for 10–12 hours.
• For electronic (for example, XM-6025): press and hold the button SET (or MODE) 10 seconds.

After resetting, the temperature will return to factory values (usually +5°C in the refrigerator compartment).

Is it possible to use the Atlant refrigerator at temperatures below +10°C (for example, on the balcony)?

No! Most models Atlant are designed to work at ambient temperature +16...+32°C. At +10°C:

• The compressor will work almost non-stop.
• The thermostat may malfunction.
• In the freezer the temperature will rise to −10...−12°C.

If you need to use the refrigerator in an unheated room, select a model with winter set (for example, Atlant MHM-1708-80 with climate class SN-T).

Why did the Atlant refrigerator begin to freeze after defrosting stronger?

Possible reasons:

• Moisture got on electronic board - drying is required (turn off for 24 hours).
• During defrosting there was The temperature sensor is damaged. work temperature sensor.
• After switching on it worked fast freezing mode (should turn off automatically).
• Ice has accumulated in the freezer - check operation No Frost.

How often do you need to adjust the temperature in the Atlant refrigerator?

Recommendations:

• 📅 Seasonal adjustment: in summer, set the thermostat 1 notch colder, in winter - 1 warmer.
• 🛒 When changing the load: if the refrigerator is almost empty, turn it warmer by 1 notch.
• 🔧 After repair: check the temperature in the first 3 days.

Normally, adjustment is required no more than once every 2-3 months.
