Buying a new refrigerator Nord is always a joyful event, marking an update to kitchen appliances, but the initial euphoria quickly gives way to the question of how to properly start the unit. Many owners make the mistake of hastily connecting the device to the power supply immediately after delivery, which can lead to serious damage to the compressor. In this article, we will look in detail at how to turn on a refrigerator Nordso that it serves for many years without failures and costly repairs.
The correct start of operation of refrigeration equipment is not just connecting the cord to the outlet, but a whole set of preparatory measures, ignoring which will void the factory warranty. You will learn why it is important to wait a certain time before starting it for the first time, how to set the correct temperature, and what sounds of a running unit you should pay close attention to. Compliance with these simple but critical rules will ensure stable preservation of products.
Modern models Nord, such as the DK, DM or DXseries, are equipped with reliable, but sensitive to operating conditions, compressors. Ignorance of basic operating rules can lead to equipment failure within the first month of use. Let's take a step-by-step look at the entire installation and startup process to avoid typical beginner mistakes.
Initial inspection and preparation of the installation site
Before thinking about connecting electricity, it is necessary to conduct a thorough visual inspection of the delivered equipment. Make sure that the case refrigerator compartment has no dents, chips or deep scratches that could have appeared during careless transportation. Pay special attention to the doors and sealing rubber bands, since even a microscopic defect in the seal will lead to constant leakage of cold and excessive energy consumption.
Choosing the right place for installation is the foundation for stable operation of the equipment. Refrigerator Nord requires free space around the case for air circulation, especially in the back part where the capacitor is located. If you plan to build the unit into a kitchen unit or install it in a niche, make sure that the gaps meet the requirements specified in the technical data sheet of the specific model Nord.
⚠️ Attention: Installing the refrigerator close to the wall or in a closed cabinet without ventilation will lead to overheating of the compressor and reduce its service life by half times.The surface on which you place the device must be perfectly flat and stable. Misalignment of the housing even by a few millimeters can cause vibration, noise during operation and improper closing of the doors. For leveling, use the adjustable support legs, which are usually located in the lower front part of the unit.

One of the most common questions that users have: should the refrigerator Nord be allowed to settle before turning on? The answer is clear: yes, this is a mandatory procedure, especially if the device was transported horizontally or at temperatures below +5°C. During transportation, compressor oil could flow from the compressor crankcase into the refrigeration system circuit, which is dangerous for water hammer.
If you were waiting for delivery in the cold season, then you cannot immediately bring the equipment into a warm room. Sudden temperature changes will cause condensation to form inside electrical circuits, which can lead to a short circuit upon first start-up. Allow the unit to warm up to room temperature unpacked for several hours.
The time required for settling directly depends on the transportation conditions:
- 🚚 Vertical transportation: if the refrigerator was transported standing, 1-2 hours are enough to stabilize the refrigerant.
- 🛌 Horizontal transportation: When lying down, the oil could flow deep into the system, so a minimum of 4-6 hours is required, and it is better to leave the device overnight.
- ❄️ Winter delivery: If the equipment is frozen, the warm-up time in the room should be at least 4 hours before connecting to the network.
What will happen if you don’t let the refrigerator settle?
Ignoring the settling time can lead to the compressor starting “dry” or with water hammer. Oil that gets into the circuit will create a blockage, and the compressor, trying to push the refrigerant, may burn or jam. Repair in this case will cost up to 70% of the price of a new device.
Do not rush to turn it on, because haste in this matter is a direct path to expensive repairs. Compressor is the heart of your refrigerator, and it needs time to return the lubricant to the crankcase and take the correct position.
Removing shipping fasteners and packaging
Before looking for the power button, you need to free the interior of the refrigerator from all fixing elements. The manufacturer Nord reliably fixes moving parts, such as shelves, drawers and doors, using tape, foam inserts and plastic ties. If you forget to remove at least one fastening tape from the inside of the door, the mechanism may not close tightly.
Carefully inspect the back wall of the refrigerator and freezer compartments. There are often shipping bolts there that hold the motor-compressor or evaporator in place. They should be unscrewed and stored in case of re-transport, although they will no longer be needed for normal use. Also remove all price tags and advertising stickers from the internal surfaces.
☑️ Checking readiness for launch
Done: 0 / 5After removing the packaging, wipe the internal surfaces with a soft, damp cloth. This will help remove factory dust and possible plastic smell that is often present in new devices. Use a weak solution of soda or a special solution for cleaning refrigerators, but avoid aggressive chemicals.
First connection to the power supply
When the preparation stage is completed and the settling time has expired, you can move on to the most crucial moment - the first turn on. Make sure that the outlet you plan to connect to Nord refrigeratoris working and grounded. The use of extension cords or tees is not recommended, as they can cause poor contact and heating of the wiring.
Plug the power cord into the outlet. In some models Nord the power button may not be present as such - the device will start working immediately upon connecting to the network. In other modifications, especially with electronic control, you may need to briefly press the power button on the control panel or inside the camera.
Once connected, you should hear the characteristic sound of the motor starting. This is a normal operating situation. However, if you hear a loud click, the buzzing stops after a couple of seconds, and then the click follows again, immediately unplug the device. Such symptoms indicate a malfunction of the start relay or a problem with the compressor.
Condition after switching on Normal reaction Alarm signal Operation sound Uniform humming, quiet rustling Loud knocking, clanging, intermittent hum Vibration of the case Barely noticeable or absent Strong trembling, "walking" on the floor Heating of the sides Warm to the touch (condenser is running) Hot to the point of being touched Indication Standard indicators are on All lamps are flashing, "Alarm" is on Setting the temperature mode
After a successful start, you are faced with the task of setting the optimal temperature mode. In refrigerators Nord with mechanical control, the thermostat, usually located inside the refrigerator compartment, is responsible for this. This is a round knob with numbers from 1 to 7 or from Min to Max.
For initial start-up, it is recommended to set the knob to the middle position (usually number 3 or 4). You shouldn’t immediately turn the knob to maximum, trying to cool the food faster. This will force compressor to work without stopping, which will lead to its overheating and possible breakdown in the first hours of operation.
In models with electronic control, the setting is made through a panel on the door or inside the chamber. Here you can set the exact temperature in degrees Celsius. The optimal value for the refrigerator compartment is +4°C...+5°C, and for the freezer -18°C.
⚠️ Attention: Do not load the refrigerator with food immediately after turning it on. Let it run idle for at least 2-3 hours (preferably up to 12 hours) so that it reaches the required temperature in empty chambers.Checking the cooling efficiency is done by placing a thermometer in the center of the chamber (not at the walls!) after several hours of operation. If the temperature differs from the set temperature by more than 2 degrees, the thermostat may need to be adjusted again.
Loading with products and entering the mode
Full loading of the refrigerator Nord with products should occur gradually. Suddenly placing a large volume of warm or even room temperature food will cause a surge in the load on the system. On the first day, it is better to load the chambers by 50% of their volume so that the unit can easily cope with cooling.
Distribute the products evenly without closing the ventilation holes inside the chamber. Air circulation is key to maintaining the same temperature in all corners of the refrigerator. If the shelves are filled to capacity, food may freeze in some areas and spoil in others.
Pay attention to the behavior of the door when loading. If, after filling with food, it no longer fits tightly or begins to open on its own, check the tilt adjustment of the housing. Heavy shelves can change the center of gravity, and the front legs will need to be tightened.
Typical sounds and behavior of a new refrigerator
A new refrigerator Nord can make sounds that are unusual for the ears of the owner of old equipment. Modern refrigerants and compressors work differently. For example, the sound of gurgling or overflowing liquid is the normal movement of freon through the system pipes, which can be heard even when the motor is not running.
Plastic cracking is also possible. This phenomenon is called thermal expansion. When cooled or heated (during defrost cycles), the plastic parts of the cabinet and internal shelves may become slightly deformed, producing a characteristic clicking sound. This is not a defect and goes away on its own after a few days.
- 🔊 Humming: a uniform low-frequency hum indicates normal engine operation.
- 💧 Burring: the sound of refrigerant flow, especially noticeable in a quiet night.
- 🧊 Clicks: activation of the thermostat or thermal expansion of materials.
However, if you hear a metallic clang, whistle or vibration that is transmitted to the furniture, you should re-diagnosis. Check if the refrigerator is touching the walls or cabinets, if the legs are aligned correctly, and if there are any loose objects inside.
Why is the refrigerator humming louder than the old one?
Modern models often have more powerful compressors to ensure energy efficiency class A+. In addition, the absence of a thick layer of snow (in No Frost systems) makes the sounds of the system more audible. If the noise level does not exceed 40 dB, this is within normal limits.
Frequently asked questions (FAQ)
Is it possible to turn on the Nord refrigerator immediately after delivery if it was transported standing?
Yes, if transportation was carried out strictly in a vertical position and did not last long, it is enough to give the device stand for 1-2 hours to stabilize the refrigerant before connecting to the network.
How long does the Nord refrigerator take to gain temperature after the first turn on?
Usually the process of primary cooling of empty chambers to the specified parameters takes from 2 to 6 hours, depending on the ambient temperature in the room and the model of the unit.
What to do if, after switching on, the red alarm light comes on?
During the first hours of operation, the red lamp (Alarm) may light up, since the temperature inside is still high. This is fine. If it does not go out after 12 hours of operation, check the tightness of the door closure and the position of the thermostat.
Is it necessary to defrost a new refrigerator before first use?
No, new refrigerators Nord are delivered clean and do not require defrosting. It is enough just to wipe the internal surfaces with a damp cloth to remove dust.
Why are the side walls of the refrigerator hot?
In modern models, the condenser (heat exchanger) is often built into the side walls of the case. Their heating to 50-60°C while the compressor is operating is a normal mode of heat removal, and not a sign of a breakdown.
