Thermostat in a Nord refrigerator: where is it located, how to check and replace

Refrigerators Nord are known for their reliability, but even they require repairs over time. One of the common malfunctions is the failure of thermostat the device that regulates the temperature in the chambers. If your refrigerator has stopped cooling, constantly works without stopping, or, conversely, turns on too rarely, the problem may lie in the thermostat. But before you run to the service center, you should figure out where the thermostat is in the refrigerator Nord and whether you can deal with the problem yourself.

In this article we will look in detail at the location of the thermostat in different models Nord (from classic to modern ones with electronic control), we will show how to identify it by appearance, and we will give step-by-step instructions for diagnosis. You will also learn what tools you will need for replacement and what to look for when purchasing a new thermostat. And for those who are afraid of making a mistake, we have prepared a unique table of compatibility of thermostats with popular models Nord of the last 10 years.

Why it is important to know where the thermostat is located

Thermostat (or thermostat) - this is "brain" a refrigerator that controls the operation of the compressor. It measures the temperature in the chamber and turns cooling on/off as needed. If the thermostat is broken, the refrigerator may:

• 🔴 Does not cool at all —the compressor does not turn on, food spoils.
• ❄️ Freeze —works without stopping, ice builds up on the walls.
• 🔄 Turns on chaotically —the cooling cycle is broken, the temperature jumps.
• 💥 Knock out the machine —when there is a short circuit in the thermostat circuit.

Knowing the exact location of the thermostat will help:

• 🔧 Quickly check its performance with a multimeter.
• 🛠️ Replace the part yourself, saving on calling a technician.
• 📞 Accurately describe the problem to a specialist if repairs are still required.

In refrigerators Nord the thermostat can be located in different places depending on models, years of manufacture i type of control (mechanical or electronic). Next, we will analyze all possible options.

Where to look for the thermostat in Nord refrigerators: 3 main places

In most models Nord the thermostat is located in one of three places. In order not to waste time on useless analysis of equipment, first determine the type of your refrigerator:

1. Classic models with mechanical control (thermostat knob inside the chamber).
2. Modern models with an electronic unit (display outside or inside).
3. Two-chamber refrigerators with separate controls (thermostats for the refrigerator and freezer compartments).

Now we will consider each location in detail.

1. Inside the refrigerator compartment (for mechanical models)

This is the most common place for thermostats in refrigerators Nord manufactured before 2015 and in budget series (for example, Nord 210, Nord 230, Nord 360). The thermostat is usually hidden under a plastic casing next to the temperature control knob.

How to find it:

1. Open the refrigerator door.
2. Inspect the inner wall on the right or left (depending on model) - there should be a handle with numbers from 1 to 7.
3. Carefully pry up the plastic cover around the handle (you can use a flat screwdriver or a plastic card).
4. Under the cover you will see a box with a tube (capillary sensor) - this is thermostat.

The tube from the thermostat runs along the chamber wall and is attached to the evaporator. Do not pull the tube —it is filled with freon and can be damaged!

What to do if the thermostat tube comes off?

If the capillary tube of the thermostat is damaged, it will have to be replaced entirely. Such sensors cannot be repaired, since a vacuum is created inside, which is broken when depressurized.

2. In the electronic control unit (for models with a display)

In refrigerators Nord after 2016 year (series Nord 510, Nord 518, Nord 620 etc.), the thermostat is often built into electronic module, which is located:

• 📱 On top of the door (in models with an external display).
• 🔄 On the back wall inside the refrigerator compartment (in models with an internal display).

In this case, the thermostat is chip or sensorconnected to the board. Replacing it requires care, as you will have to work with electronics. If you are not confident in your skills, it is better to contact a specialist.

Signs of a faulty electronic thermostat:

• 🔢 The display shows incorrect temperature (for example, -18°C at room temperature).
• 🔄 The refrigerator reboots spontaneously.
• 🚨 Errors appear on the display (codes E1, E2, E5 —check the instructions).

3. In the freezer compartment (for two-chamber models)

In two-chamber refrigerators Nord (for example, Nord 380, Nord 400) they are often installed two thermostats: one for the refrigerator compartment, the second for the freezer. The second thermostat is usually located:

• 🧊 Inside the freezer compartment on the top or side wall (under the plastic panel).
• ❄️ On the outside on the back wall refrigerator (in models with the system No Frost).

To get to the freezer thermostat, you will have to defrost the refrigerator remove the inner lining. Be careful - ice often accumulates in the freezer, which can damage parts if dismantled carelessly.

What the thermostat looks like in a Nord refrigerator: photos and diagrams

Thermostats in refrigerators Nord may differ in appearance, but they have common features:

• 📦 Case —a plastic or metal box measuring 5x5 cm (for mechanical models).
• 🔗 Capillary tube —a thin copper or aluminum tube coming from the case to the evaporator.
• 🔌 Terminals for wires —usually 2-4 contacts for connecting to the electrical circuit.
• 🔢 Marking —numbers and letters are printed on the body (for example, K59-L1431, Danfoss 077B6).

Below are photographs of thermostats from popular models Nord:

If your model is not indicated in the table, pay attention to thermostat marking. It is usually marked on the case or indicated in the operating instructions. Using this code, you can select a similar thermostat for replacement.

How to check the thermostat in a Nord refrigerator with a multimeter

Before changing the thermostat, make sure that it is the problem. This will require multimeter (tester) and a little patience. Here are step-by-step instructions:

Disconnect the refrigerator from the mains

Remove all products from the chamber

Remove the plastic cover from the thermostat

Disconnect the wires from thermostat terminals (take a photo of the connection diagram!)

-->

Step 1: Check for open circuit

Set the multimeter to mode continuity (or resistance measurement on 200 Ohm). Connect the probes to the thermostat terminals:

• If the device shows 1 (open) - the thermostat is faulty.
• If there is resistance (usually 0–50 Ohm) - proceed to the next step.

Step 2: Checking in different knob positions

Turn the thermostat knob to position MAX (or 7) and measure the resistance again:

• 🔴 If the resistance does not change, the thermostat is stuck.
• 🟢 If the resistance drops to 0 Ohm —the thermostat is working.

Step 3: Checking the capillary tube

Carefully warm the thermostat tube with your hands or lower it into warm water (40–50°C). A working thermostat should:

• 🔊 Click (open the contacts) when heating.
• 📉 Show on the multimeter break (resistance 1).

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

Step-by-step instructions for replacing the thermostat in a Nord refrigerator

If the diagnostics have confirmed that the thermostat is faulty, you can proceed with replacement. For work you will need:

• 🔧 Screwdrivers (Phillips and flathead).
• 🔌 New thermostat (analogous to the old one in markings).
• 📸 Camera (to fix the connection diagram).
• 🧰 Pliers and electrical tape.

Replacement time: 30–60 minutes (depending on the model).

Step 1: Turn off the refrigerator and defrosting

Unplug the refrigerator and wait for complete defrosting (if there is ice). Do not use a hair dryer or hot water to speed up the process - this can damage the seals.

Step 2: Dismantling the old one thermostat

Carefully remove the plastic cover around the thermostat handle. Disconnect the wires from the terminals (remember or take a photo of the connection order!). Unscrew the fastening screws and remove the thermostat along with the capillary tube.

Attention! Do not pull the tube - it is fragile. comes off, you will have to change the entire thermostat.

Step 3: Installing a new thermostat

Place the new thermostat in place of the old one and secure it with screws. Make sure that the capillary tube lies flat and does not. pinched.

Step 4: Checking operation

Turn on the refrigerator and set the temperature to medium (for example, 3–4 on the handle). Check:

• 🔊 Whether the compressor starts.
• ❄️ Does the refrigerator begin to cool.
• 🔄 Does the compressor turn off after reaching the set temperature.

If everything works, the replacement can be considered successful!

How to choose a replacement thermostat: compatibility with Nord models

Not all thermostats are suitable for refrigerators NordWhen buying a new one, pay attention to:

1. Marking (must match the old one). thermostat).
2. Type of fastening (screws, latches).
3. Length of the capillary tube (must be no shorter than the original one).
4. Voltage (usually 220V for mechanical, 5–12V for electronic).

The table below shows the compatibility of thermostats with popular models Nord:

If you are not sure about the choice, take the old thermostat with you to the store or order a part according to its markings in an online spare parts store.

⚠️ Attention: In some models Nord after 2020, thermostats with digital calibration are installed. They require adjustment after replacement (usually this is done through the service menu). Check this point with the seller!

Common mistakes when replacing a thermostat and how to fix them. avoid

Even experienced craftsmen sometimes make mistakes when working with thermostats. Here are the most common ones and ways to prevent them:

• 🔌 Incorrect connection of wires → Always photograph the circuit before disconnecting!
• 🧊 Kink in the capillary tube → Lay it loosely, without tension.
• 🔧 Using an incompatible thermostat → Check the markings and length of the tube.
• 🔥 Operation under voltage → Unplug the refrigerator before disassembling!
• ❄️ Incomplete defrosting before replacement → Ice can damage new parts.

Another typical mistake - ignoring the check after replacementAlways test the refrigerator within 24 hours to make sure. that:

• The temperature is stable.
• The compressor turns off periodically.
• No freon leaks (if the tube was damaged).

⚠️ Attention: If after replacement The thermostat still does not cool the refrigerator, the problem may be in compressor, start relay or freon leak. In this case, professional diagnostics will be required.

FAQ: Frequently asked questions about thermostats in Nord refrigerators

Can the thermostat be repaired or just replaced?

Thermostats in refrigerators Nord cannot be repaired - they can be only replace. This is due to the tightness of the capillary system and the precise calibration of the sensors. The exception is electronic thermostats, where sometimes it is possible to replace a separate sensor (for example, NTC), but this requires skills in working with a soldering iron.

Which thermostat is suitable for Nord 210?

For the model Nord 210 original thermostat - K59-L1431. Suitable analogs: Danfoss 077B6, Ranco K59, Orbis K59. The main thing is that the length of the capillary tube is at least 1 meter.

What to do if after replacing the thermostat the refrigerator does not turn on?

Check:

1. The correct connection of the wires (compare with the diagram).
2. The voltage in the socket (the machine may have tripped).
3. The compressor start relay (sometimes it fails when the power is turned off).

If everything is in order, but the refrigerator does not work, the new thermostat may be defective.

Is it possible to replace a mechanical thermostat with an electronic one?

Technically this is possible, but it will require serious modifications to the electrical circuit of the refrigerator. In most cases, it is easier and cheaper to install a similar mechanical thermostat. Electronic thermostats are only suitable for models Nord with factory electronic control (for example, series 510, 620).

How much does it cost to replace a thermostat in a service center?
