How to properly turn off the upper chamber in two-chamber Atlant refrigerator: 3 proven methods

The upper chamber in modern refrigerators Atlantic is not just a temperature sensor, but part of a complex climate control system. It is responsible for the correct operation of the mode No Frost, humidity control and even signals problems. However, some users are faced with the need to disable it - be it due to false alarms, saving energy, or preparing for repairs. It is important to understand: arbitrarily turning off the camera without a good reason can lead to a malfunction of the freezer and accelerated ice formation.

In this article we will look at when it is really necessary to deactivate the top sensor, which models Atlant support this function (spoiler: not all!), and provide step-by-step instructions with taking into account the type of refrigerator control - mechanical or electronic. You will also learn how to check whether the shutdown has affected the performance of the unit, and what to do if malfunctions appear after the manipulations.

Why might it be necessary to turn off the upper chamber?

At first glance, the idea of ​​“turning off” the standard sensor seems dubious - after all, the manufacturer provided it for stable operation of the equipment. However, there are several justified reasons:

• 🔧 False errors: The refrigerator issues a fault code (for example, E1 or E3), although visually everything works fine. This is often due to contamination or oxidation of the camera contacts.
• ⚡ Saving energy: In some models, the sensor consumes up to 5-7% of the total energy consumption of the unit. If you rarely use the freezer, turning it off can reduce your electricity bills.
• 🔨 Preparation for repairs: If you plan to replace the compressor or evaporator, technicians recommend temporarily deactivating the chamber to avoid short circuits.
• ❄️ Problems with No Frost: If the automatic defrosting system does not operate correctly, the sensor may cause excessive icing.

Important: before turning it off, check whether the refrigerator’s “glitches” are not due to other reasons. For example, code E1 v Atlant MXM 2835-90 often appears due to blockage of the drainage holerather than a camera malfunction. Diagnose the unit for instructions in the FAQ.

Which Atlant models allow you to turn off the upper chamber?

Not all refrigerators Atlantic support manual switching off of the sensor. The possibility depends on type of control system and the year of manufacture of the model. Below is a compatibility table:

Please note: in models with inverter compressor (for example, Atlant NM 6021-000) turning off the camera may cause the motor algorithm to fail. In this case, it is better to contact a service center.

⚠️ Attention: If your refrigerator was manufactured before 2016, there is a high probability that the upper chamber is integrated into the system without the possibility of software shutdown. Attempts to physically disconnect may damage the control board.

Method 1: Disabling through the service menu (for electronic models)

The safest method is to use hidden refrigerator settings. It is suitable for models with a display (MXM, NM etc.). Follow the instructions:

Enter the service menu (press "Freezer" + "Refrigerator" for 5 seconds)

Go to section Sensors using buttons «+»

Select item Upper Camera (upper chamber)

Press "OK" to deactivate (the value will change to OFF)

Save settings button “M” and reboot the refrigerator (unplug it for 1 minute)-->

If the menu is in English, focus on the order of the items:

1. Temperature Sensors

2. Defrost System

3. Upper Chamber Control —this is the desired section.

After turning off, the refrigerator may make a beeping sound. After 10-15 minutes, the operation will stabilize. To return the camera to operation, repeat the steps and select ON.

Method 2: Physically disconnecting the camera (for mechanical models)

In refrigerators with mechanical controls (series XM, MX), software shutdown is impossible. disassembling the case.

You will need:

• 🔧 Phillips screwdriver (PH2)
• 🧲 Multimeter (for checking contacts)
• 📸 Telephone to photograph the connection diagram

Action algorithm:

1. Unplug the refrigerator and wait for complete defrosting (at least 6 hours).

2. Remove the top cover of the freezer by unscrewing the 4 screws on the back.

3. Find the control board - it is located on the right or on the top, under the protective casing.

4. Disconnect the connector marked CAM-UP or UPPER SENSOR (wire colors are usually red and black).

5. Insulate the contacts with heat-shrink tubing or electrical tape.

⚠️ Attention: If after disconnecting the refrigerator stops freezing or displays an error E5, then the sensor was critical for the operation of the compressor. In this case, return the connector to its place and contact service.

What to do if not. markings on the connector?

If the wires are not labeled, use a multimeter in circuit test mode. Touch the connector contacts with the probes - the resistance of a working camera should be in the range of 5–15 kOhm. If the indicator is 0 or ∞, the sensor is faulty and its replacement is inevitable.

Method 3: An alternative solution is to reset the settings to factory settings.

If the camera does not work correctly, but you don’t want to turn it off, try returning the refrigerator to factory settings. This helps in 60% of cases of false sensor alarms. Instructions:

For models with a display:

1. Press and. hold «Super Cool» + «Holiday» 10 seconds.
2. After the beep, release the buttons - the screen will appear rSt.
3. Confirm the reset with the button "OK".

For mechanical models:

1. Turn the freezer temperature control to position OFF.

2. Unplug the refrigerator for 24 hours.

3. Plug it back in and set the regulator to 3–4 (average value).

After the reset, the refrigerator Atlant will automatically recalibrate the sensors. If the problem persists, it means that the camera is physically faulty and requires replacement.

What happens if you disable the top camera: possible consequences

Deactivation of the sensor does not go without leaving a trace. Here's what to expect:

• ❄️ Increased icing: Without temperature control in the upper zone of the freezer, ice will build up faster. You will have to defrost the refrigerator 2-3 times more often.
• ⚡ Increased energy consumption: The compressor will work longer, trying to compensate for the lack of data from the sensor. Electricity consumption may increase by 10–15%.
• 🔊 Increased noise: In models with No Frost the fan may start working continuously, since the system does not receive a signal that the desired temperature has been reached.
• 🚨 Loss of warranty: If the refrigerator is under warranty, any manipulations with the sensors are equivalent to self-repair and void the manufacturer's obligations.

On the other hand, if the camera was initially faulty, its shutdown may normalize operation refrigerator. For example, a Atlant MXM 2835-90 broken sensor often provokes constant operation of the compressor, which leads to overheating. In this case, deactivation is a temporary solution until the part is replaced.

How to check whether the shutdown affected the operation of the refrigerator?

After manipulating the camera, it is necessary to evaluate whether the key parameters. Here's what you need to do:

1. Measure the temperature in the freezer 12 hours after turning off. Optimal values:
   • 🥶 Freezer: –18°C ± 2°C
   • ❄️ Refrigerator: +4°C ± 1°C

Listen to the compressor: normally it should turn on for 10–15 minutes and turn off for 20–30 minutes. If the cycles become shorter or longer, this is a sign of a malfunction.

Evaluate the ice: if after 24 hours frost more than 3 mm thick appears on the walls of the freezer, it means that the defrosting system is not working effectively.

For accurate measurements, use infrared thermometer or place an outdoor thermometer in a glass of water inside the refrigerator compartment. If the readings are outside the normal range, return the camera to working condition and contact a specialist.

⚠️ Attention: In refrigerators with a system Total No Frost (for example, Atlant NM 6208-100), disconnecting the upper chamber may lead to fan failure. Check its operation by placing your ear to the back wall - a uniform noise should be heard.

FAQ: Frequently asked questions about turning off the camera in the Atlant refrigerator

Is it possible to turn off the camera without disassembling the refrigerator?

Yes, but only in models with electronic control (series MXM, NM). To do this, use service menu. In mechanical refrigerators (XM, MX), you cannot do without physical disconnection.

After the camera was turned off, the refrigerator began to hum loudly. What to do?

This is a normal reaction of the system No Frost to the lack of data from the sensor. The fan is running at maximum power, trying to cool the camera. Solutions:

1. Return the camera to working condition.
2. Reduce the temperature in the freezer by 1-2 degrees manually (if the model supports adjustment).
3. Check whether ice is blocking the fan blades - defrost the refrigerator if necessary.

How to understand that the camera is faulty and not just glitchy?

Signs of physical damage to the sensor:

• The refrigerator gives an error E1, E3 or E5 even after resetting the settings.
• The temperature in the freezer drops to –24°C and below, or, conversely, does not fall below –10°C.
• The display shows incorrect values (for example, +10°C in the freezer).
• The multimeter shows an open circuit (resistance ∞) or a short short circuit (0 Ohm).

In this case, the sensor must be replaced.

How much does it cost to replace the upper chamber at a service center?

The cost depends on the refrigerator model and region:

Service	Price (RUB)
Fault diagnosis	500–1 200
Replacement of the sensor (without the cost of the part)	1 500–3 000
Price of the sensor (original)	800–2 500

Average bill for a complete replacement (with the part) - 3 000–5,500 rubles. Some services offer used sensors cheaper, but the warranty on them usually does not exceed 3 months.

Is it possible to use a refrigerator with the chamber turned off all the time?

Technically yes, but with reservations:

• 🔹 Defrost the freezer every 2-3 months (instead of the standard 6-12).
• 🔹 Monitor the temperature using an external thermometer.
• 🔹 Be prepared for an increase in energy consumption by 10-20%.
• 🔹 In models with No Frost check the condition of the fan once a month.

For long-term operation, it is better to replace the faulty sensor or contact a service to reconfigure the control board.
