How to do it correctly turn the refrigerator on and off: step-by-step instructions

It seems that turning the refrigerator on or off is as easy as shelling pears - just press a button or turn a knob. But in practice, even this elementary procedure has nuances that affect the durability of equipment, product safety and energy consumption. Errors when starting up a new unit for the first time can lead to breakdown of the compressor, and incorrect shutdown can lead to food spoilage or mold formation.

In this article we will examine all methods of turning it on/off for different types of refrigerators: from mechanical models with a rotary thermostat to modern devices with touch controls and system No Frost. We will separately focus on emergency situationswhen equipment refuses to respond to commands, and on how to minimize risks during prolonged downtime.

If you have just purchased a refrigerator or are planning to transport it/turn it off during your vacation - here you will find answers to questions that are rarely covered in standard instructions. For example, why you can’t turn on the unit immediately after transportation, how to properly “defrost” the electronic panel after a power surge, and what to do if the refrigerator turns on but turns off immediately turns on after 5-10 seconds, but immediately turns off

1. Preparing the refrigerator for the first use

A new refrigerator cannot be turned on immediately after delivery - this is one of the key rules that is often ignored. The fact is that during transportation compressor oil it can get into the refrigerant circuit. If you start the engine right away, this will lead to breakdown. The waiting time depends on the position in which the equipment was transported: hydraulic shock and breakdown. The waiting time depends on the position in which the equipment was transported:

• 🚛 Vertical (standard position) - 2-4 hours is enough.
• 🔄 At an angle or horizontally - at least required 6–8 hours (and for some models Samsung and LG up to 24 hours).
• ❄️ At low temperature (in winter) - before turning on, let the refrigerator warm up to room temperature.

While the unit is “settling”, perform the following steps:

Remove all transport bolts and brackets (usually they secure the compressor and doors)|Wipe the internal surfaces with a weak solution of soda (1 tablespoon per 1 liter of water)|Check the door seals for damage|Place the refrigerator on a flat surface (use level)|Connect to a grounded outlet (not through an extension cord!)

-->

Pay special attention transport bolts —they forget to remove them in 30% of cases (according to service centers). These fasteners secure the compressor springs, and if they are not removed, the motor will work with increased load, which will shorten its life. Usually the bolts are located on the back wall - their number depends on the model (there are 3–4 of them, and 2 large ones). Indesit And Atlant there are 3–4 of them, Bosch - 2 large ones).

⚠️ Attention: If the refrigerator was transported in a lying position and you turned it on before 6 hours, listen to the sounds of the compressor. Loud knocking or vibration in the first minutes of operation is a sign of water hammer. Immediately turn off the equipment and call a technician.

2. How to turn on the refrigerator: mechanics vs electronics

The method of turning on depends on the type of control. Let's consider both options.

Mechanical control (rotary control)

Such refrigerators (Biryusa, Nord, Snaige and budget models Atlant) are turned on by turning the thermostat. Algorithm:

1. Connect the plug to the socket (preferably with UPS or a voltage stabilizer).
2. Find the temperature regulator - usually it is located inside the chamber (less often - on the top panel).
3. Turn the knob clockwise until it clicks or the first division (this is the position "On.").
4. Set the desired temperature (optimally - +4…+5°C for the refrigerator and -18°C for the freezer).

On some models (for example, Minsks) the knob has a position «0» —this is “Off.” If you turn it further clockwise, the refrigerator will turn on. Do not turn the knob all the way —this is the maximum cooling mode, which is only needed for quick freezing.

Electronic control (sensor or buttons)

Modern refrigerators (Samsung RB, LG InstaView, Bosch Serie 6) are equipped with a display and buttons. Switching on process:

1. Connect to the power supply OFF or. blink --.
2. Press the button Power (sometimes it is combined with Menu). For some models Liebeherr you need to hold it for 3 seconds.
3. The current temperature or settings menu will appear on the display. Select a mode (for example, Eco, Super Cool or Holiday).
4. Adjust the temperature using the buttons +/–.

In refrigerators with a system No Frost after turning on, the fan may work - this is normal. If after 5-10 minutes it does not stop making noise, check if the air channels are blocked (for example, products).

3. How to turn off the refrigerator correctly

Switching off the refrigerator is required in three cases: for defrosting, moving or long inactivity (for example, at the dacha in winter). Each case has its own nuances.

Short-term shutdown (defrosting, cleaning)

If the refrigerator needs to be turned off for several hours:

• 🧊 For models with a drip system (Atlant, Indesit): turn the thermostat to position «0» or OFF.
• ❄️ For No Frost (Samsung, LG: press the button Power or select from the menu Holiday Mode (if you are leaving for 1-2 weeks).
• 🔌 Remove the plug from the socket - this will protect against power surges during defrosting.

After turning off:

• Leave the doors open for ventilation (if the refrigerator is not No Frost).
• Remove all food in cooler bag or in a cool place.
• Place containers to collect melt water (if defrosting manually).

Long shutdown (more than 2 weeks)

If the refrigerator will not be used for a long time (for example, at the dacha in winter):

1. Turn it off 12-24 hours before departure so that the ice melts and moisture evaporates.
2. Wash and dry the cameras thoroughly (use towels or a hairdryer).
3. Leave the doors ajar (you can put a towel) to avoid mold.
4. Place an odor absorber inside (for example, a bag of soda or activated carbon).
5. Unplug from the network - even when turned off, some models consume energy (for example, to operate the display).

⚠️ Attention: If you turn off the refrigerator with the system No Frost for a period of more than a month, necessarily dry the evaporator (it is located behind the back panel of the freezer). Humidity in a closed space will lead to rust and failure of the fan.

4. What to do if the refrigerator does not turn on

If, after connecting to the network, the refrigerator does not show signs of life, check the following:

• 🔌 Socket and cable: connect another device (for example, a hair dryer) to this outlet to make sure there is voltage. Check the plug and cord for damage.
• ⚡ Fuse: in some models (Snaige, old Zanussi) it is located on the compressor. If it is blown, a replacement is needed.
• 📛 Display: If an error flashes on the electronic panel (for example, E1, F2), check its value with the instructions. A common reason is closed freezer door (the blocking sensor acts as protection).
• ❄️ Thermostat: in mechanical models, if the thermostat breaks down, the compressor does not start. You can check by closing the relay contacts directly (but this is dangerous - it’s better to call a technician).

If the refrigerator is hums, but does not freeze, the problem may be:

• Refrigerant leak (refill required).
• Clogged capillary tube (needs cleaning).
• Faulty start relay (a common problem in Atlant i Indesit after 5 years of operation).

How to check if the compressor is working?

If the refrigerator is turned on but is not cooling, put your hand on the back wall at the bottom (where the compressor is located). If it hot the motor is running, but there is a problem with the refrigerant or thermostat. If cold —the relay or the compressor itself is faulty. Do not try to repair it yourself - there is a risk of electric shock!

In 20% of cases (according to service centers), the refrigerator does not turn on due to activation of protection against power surges. After a power outage, some models (LG, Samsung) are blocked for 5–10 minutes. In this case, it is enough to wait and repeat the switching on.

5. Why does the refrigerator turn on and immediately turn off

If the compressor starts for a few seconds and stops, this may be a sign:

The most common reason is faulty start relay. It is responsible for starting the compressor, and if it breaks down, the motor cannot reach the required speed. In this case, a characteristic sound is heard clicking, after which the refrigerator turns off. The relay is inexpensive, but replacing it requires disassembling the back panel.

If the problem is low voltagethe compressor will try to start again and again, but to no avail. This is dangerous - the motor winding may burn out. Solution: connect the refrigerator via voltage stabilizer (optimal range - 200–240 V).

⚠️ Attention: If the refrigerator turns on and off with an interval of 1–2 minutes, do not ignore the problem - this leads to overheating of the compressor and its complete failure within 1-3 months. The longer you delay repairs, the more expensive it will cost.

6. Features of switching on after defrosting or moving

After defrosting or transporting the refrigerator, you cannot turn it on. immediately. Here's what you need to do:

After defrosting

• 🧽 Wipe all surfaces dry (moisture can short the contacts).
• 🕒 Wait 30-60 minutes for the temperature inside the chambers to equal room temperature.
• ⚡ Turn on the refrigerator and let it run empty 1-2 hours before loading food.

After moving

• 🚚 As already mentioned, wait 6-24 hours (depending from the position during transportation).
• ☑️ Check whether the refrigerant pipe is damaged (it goes along the back wall). If there are dents or cracks, do not turn on the refrigerator, it is dangerous!
• 🔧 Make sure that condenser (the grille on the back wall) is not bent or clogged with dust.

If the refrigerator was transported in winter, before turning it on acclimatize - let it stand in a warm room for 12–24 hours. This is due to the fact that the oil in the compressor thickens in the cold, and the motor may not start.

7. Safety: what not to do when turning on/off

Several actions that seem harmless, but can lead to breakdown:

• ❌ Turn on the refrigerator immediately after unplugging it. The compressor needs 5-10 minutes to relieve pressure in the system. Ignoring this rule is the cause of 15% of motor breakdowns.
• ❌ Use an extension cord without grounding. A voltage surge can damage the electronic unit.
• ❌ Turn off the refrigerator by simply unplugging the plug. In models with electronic control, this can lead to firmware failure.
• ❌ Leave the doors closed during prolonged periods of inactivity. This leads to mold and rust.
• ❌ Disassemble the compressor or thermostat yourself. Risk of electric shock or refrigerant leakage.

Especially dangerous connect the refrigerator to a network with a voltage below 190 V or above 250 V. In the first case, the compressor will not start, in the second it will burn out. If there is unstable voltage in your house, be sure to use voltage control relay (for example, ZUBR R116y or DigiTOP VA-32).

⚠️ Attention: If you connect the refrigerator via UPS (uninterruptible power supply), make sure that its power exceeds the starting current of the compressor (usually 3-5 times higher than the nominal one). For example, for a refrigerator with a consumption of 150 W, a 600-800 W UPS is needed.

8. data-i="271">❓ Is it necessary to defrost a refrigerator with No Frost?

❓ Do you need to defrost a refrigerator with No Frost?

Yes, but less often - once every 1-2 years. The system No Frost prevents the formation of ice, but does not completely remove moisture. Over time, frost accumulates on the walls, and mold may appear in the drainage hole. To maintain it, just turn off the refrigerator. wash it and dry it.

❓ Why does the refrigerator turn on at night when no one opens the door?

This is normal! Modern refrigerators are equipped with sensors that analyze the temperature and turn on the compressor as needed. At night, the room temperature is usually lower, and the motor runs less often, but can start to maintain the set mode. If the noise is disturbing, check whether the refrigerator is touching the wall. (vibration increases the sound).

❓ Is it possible to turn on the refrigerator without the back cover?

No! The back cover protects condenser from dust, moisture and mechanical damage. Working without it leads to overheating of the motor and shortens its service life. is damaged, replace it with the original one (for popular models it costs 500–1500 rubles). compressor from dust, moisture and mechanical damage. Working without it leads to overheating of the motor and shortens its service life. If the cover is damaged, replace it with the original one (for popular models it costs 500–1500 rubles).

❓ How long should the refrigerator work after turning on to cool?

The time depends on volume of chambers and room temperature:

• Small refrigerator (up to 150 l) - 1-2 hours.
• Medium (200-300 l) - 3-4 hours.
• Large (350 l or more) - 5-6 hours.

If after 6 hours the temperature in the chamber has not dropped to +5°C, check the tightness of the doors and thermostat settings.

❓ What to do if, after turning on, the refrigerator gets very hot on the sides?

This is normal for models with with a capacitor on the side walls (for example, Bosch KAN92VI30R or Liebherr CNesf 4866). Heat is released into the room to maintain thermal balance. If the walls are hot, but the compressor works without stopping, and the temperature in the chamber does not drop, this is a reason to call a technician.
