How to turn on an LG refrigerator: instructions for all models

The refrigerator LG does not turn on after moving, defrosting or turning off electricity? Or have you just bought new equipment and don’t know how to start it correctly? In this article we will analyze in detail all the ways to turn on refrigerators LG - from simple models without a display to modern ones Smart Inverter with touch control. You will learn what to do if the refrigerator does not respond to buttons, how to reset errors and why the equipment may not start after transportation.

It is important to understand that the startup procedure depends on model type, the year of manufacture and even on whether the equipment was previously in use. For example, refrigerators LG with a system DoorCooling+ require a special approach to the first start-up, and models with linear compressor may have a start delay of up to 5 minutes. We have collected current instructions for all popular series - from budget GA-B419 to premium GR-B247JHQZ.

If your refrigerator LG does not turn on despite all efforts, at the end of the article you will find checklist for troubleshooting and FAQ with answers to frequently asked questions. And for those who are just planning a purchase, we have added a comparative table of the features of switching on different series.

Preparing the LG refrigerator for the first use

Before connecting the refrigerator LG to the network, you must complete several mandatory steps - this applies to both new and used equipment. Neglect of preparation can lead to compressor malfunctions or activation of emergency modes.

For new refrigerators LG (especially with the system No Frost) it is critical to wait until transportation:

• 📦 Horizontal transportation (lying): wait at least 6-8 hours before turning on, so that the oil from the compressor is evenly distributed.
• 🚛 Vertical transportation (standing): 2-3 is enough hours to stabilize the refrigerant.
• ❄️ Winter delivery (at temperatures below +5°C): allow the refrigerator to warm up to room temperature within 4-6 hours.

⚠️ Attention: If turn on the refrigerator LG immediately after horizontal transportation, the compressor may work with overload, which will lead to its premature wear. In some models (for example GB-B459SLQZ), protection is triggered and the appliance simply will not start.

Before connecting to the network:

1. Make sure that the outlet is grounded and designed for the power of the refrigerator (usually 100-200 W, but for models with double compressor may be required 300 W).
2. Check the integrity of the power cord - there should be no kinks or melting on it.
3. Install the refrigerator on a flat surface (allowable slope - no more than 2°). Use the front legs for adjustment.

If the refrigerator LG has been in use before, it is recommended to carry out reset settings before turning it on (instructions in the next section). mode Vacation) can block normal operation.

Ways to turn on an LG refrigerator depending on the model

Refrigerators LG are divided into three main categories according to the type of control, and each has its own nuances of inclusion. Let's consider them in detail.

1. Models without a display (mechanical control)

These are the simplest refrigerators LG, such as series GA-B309 or GA-B359. To turn them on:

1. Connect the plug to the outlet - the power indicator on the front panel should light up (usually green or red).
2. Turn the thermostat (usually located inside the refrigerator compartment) to position 1-4 (where 1 is the minimum cooling, 4 is the maximum).
3. Wait for the characteristic click of the relay - this is a signal to start the compressor Normally, it should occur within 1-3. minutes.

If the refrigerator does not turn on:

• 🔌 Check if the circuit breaker in the panel (refrigerators LG are sensitive to power surges).
• ❄️ Make sure the door is tightly closed - some models have open door protection.
• ⏱️ Wait up to 10 minutes: in refrigerators with inverter compressor there may be a start delay.

2. Models with electronic display (touch or button control)

This category includes the popular series GB-B459, GR-B247 i GS-X961. Switching algorithm:

1. Connect the refrigerator to network. The message OFF should appear on the display or the indicator should blink.
2. Press and hold the button Power (or On/Off) until a beep sound is heard. 3-5 secondsuntil a beep sounds.
3. The current temperature or inscription will appear on the display COOLING. Set the desired mode using the buttons +/– or touch arrows.

In models with Smart ThinQ (for example, GR-D247HLS) after switching on, you may need to connect to Wi-Fi to activate additional functions. If the display shows an error (for example, Er IF or Er FF), see the section on resetting errors.

3. Wi-Fi and voice control

Premium models like LG Instaview (GR-X961DL) or LG ThinQ (GSX960) have advanced inclusion functions:

• 📱 Can be turned on remotely via the application LG ThinQ (preliminary registration required setting).
• 🗣️ Supports voice control via Google Assistant or Amazon Alexa (command: “Okay, Google, turn on the refrigerator”).
• 🔋 They have a mode Eco, which automatically optimizes energy consumption when turned on for the first time.

For the first start of such models:

1. Connect the refrigerator to the network and wait for the system to boot (the logo appears on the display LG).
2. Follow the instructions on the screen to connect to Wi-Fi (you will need to enter the password for your network).
3. Register device in the application LG ThinQ for remote control.

What to do if the LG refrigerator does not turn on

If after connecting the refrigerator to the network LG shows no signs of life, do not rush to call a technician. In 70% of cases the problem is solved on its own. Let's look at typical causes and ways to eliminate them.

1. There is no response to the buttons, the indicators do not light up

This is the most obvious sign of a lack of power. Check:

• 🔌 Socket: connect another device (for example, a phone charger) to make sure it is working.
• ⚡ Vending machine in the panel: refrigerators LG are sensitive to voltage surges, and the machine could work.
• 🔌 Power cord: inspect it for damage. In models with detachable cable (for example, GR-B227JVQA), check the tightness of the connection with the connector on the rear panel.

If there is power, but the refrigerator does not turn on, try emergency reset:

1. Disconnect the refrigerator from the network for 10 minutes.
2. Press and hold the button Power (or Freezer + Fridge simultaneously) for 15 seconds.
3. Connect the refrigerator back to the network.

2. The refrigerator hums, but does not cool

If the compressor is running (noise is heard), but the temperature in the chambers does not drop, the following reasons are possible:

• ❄️ The fan is frozen (valid for models with No Frost). Turn off the refrigerator for 12 hours to completely defrost.
• 🔧 Temperature sensor failure. Try resetting the settings (see next section).
• 🔋 Compressor malfunction. In this case, diagnostics by a service center will be required.

In refrigerators LG s dual compressor (for example, GC-B247JLQV), check whether at least one of the chambers is working. If the freezer cools but the refrigerator does not (or vice versa), the problem may be the separate cooling circuit.

3. An error appears on the display (Er IF, Er FF, Er dH)

Refrigerators LG with electronic control display error codes that help diagnose the problem. Here are the most common ones:

To reset the error:

1. Unplug the refrigerator.
2. Press and hold the button Freezer (freezer compartment) for 10 seconds.
3. Connect the refrigerator back. The error should disappear.

How to reset an LG refrigerator to factory settings

Resetting the settings helps eliminate software glitches that may block the refrigerator from turning on. This procedure is relevant for models with electronic control (series GB, GR, GS). In mechanical refrigerators, a reset is not required - just turn off the power for 10 minutes.

Instructions for resetting:

1. Disconnect the refrigerator from the network.
2. Press and hold the buttons simultaneously Freezer (freezer compartment) and Fridge (refrigerator compartment) for 8-10 seconds.
3. Without releasing the button, connect the refrigerator to the network.
4. Wait for a sound signal or flashing of all indicators - this is a sign of success reset.
5. Release the buttons and set up the refrigerator again.

In models with a display, after a reset the following messages may appear:

• CL — memory clearing.
• 0 or – – —factory settings temperature.
• dE —demonstration mode (must be disabled through the menu).

For refrigerators LG s Wi-Fi (for example, GR-D247HLS) after resetting, you will need to reconnect to the network and configure application LG ThinQ.

What will happen if you do not reset the settings after buying a used refrigerator?

The previous owner could activate modes that interfere with normal operation: Vacation (energy saving during long absence), Child Lock (locking buttons) or Eco (reduced cooling capacity). Without a reset, the refrigerator may not cool to the required temperature or may not respond to commands.

Features of turning on after defrosting or power outages

Refrigerators LG with the system No Frost do not require regular defrosting, but after an emergency power outage or forced defrosting, their inclusion has nuances.

1. Turning on after defrosting

If you defrosted the refrigerator manually (for example, due to icing in models with a drip system), before turning on:

• 🧽 Carefully wipe all surfaces from moisture - drops of water can cause a short circuit in the electronic units.
• ⏳ Allow let the refrigerator stand with the door open 30-60 minutesso that the moisture in the seals evaporates.
• 🔌 Connect to the network and wait until the temperature stabilizes (at first 2-3 hours the compressor can work without stops).

In models with No Frost after defrosting it may work accelerated cooling mode (Power Cool or Express Freeze). It will automatically turn off after 6-12 hours.

2. Turning on after a power outage

If the power was turned off for a short time (before 2 hours), the refrigerator LG will turn on automatically when power is restored. However, in some cases, a manual start is required:

• 🔋 If the shutdown was long (more than 4 hours), the refrigerator may go into protective mode. Press Power to restart.
• ⚡ With frequent power surges, triggered overvoltage protection. In this case, only complete disconnection from the network for 5 minutes will help..
• ❄️ In freezers with No Frost after disconnection, ice may form on the fan. If after switching on you hear a hum, but there is no cooling, defrosting is required.

In refrigerators LG s inverter compressor (series Inverter Linear Compressor) after a long power outage it may work diagnostic mode. The display will show Ch or dE —this is normal, just press any button to continue.

Frequent errors when turning on an LG refrigerator and how to avoid them

Many problems with turning on refrigerators LG arise due to ignorance of the technical features or inattention. Here are the most common mistakes and ways to prevent them:

• ⏳ Do not wait time after transportation. As already mentioned, models with linear compressor (for example, GA-B459) require at least 6 hours before turning on. Ignoring this rule leads to water hammer compressor one of the most expensive breakdowns.
• 🔌 Use extension cords or tees. Refrigerators LG are sensitive to power quality, and the use of unstable sources can lead to malfunctions of the electronic unit.
• ❄️ Turning on a refrigerator with a frozen evaporator. In models with No Frost if defrosting is incorrect, ice can block the fan, which will lead to an error Er IF.
• 🔧 They forget to remove the transport bolts. This is true for new refrigerators - if the bolts are not removed, the compressor will vibrate and the equipment simply will not turn on.
• 📱 They do not update the firmware in smart models. Refrigerators LG ThinQ require regular software updates, otherwise failures may occur when turned on.

Another typical mistake is ignoring sound signals. Refrigerators LG make different sounds:

• 🔔 One short signal —normal switching on.
• 🔔🔔 Two beeps —door open.
• 🔔🔔🔔 Three beeps —error (display check required).
• 🔊 Long beep —compressor protection has tripped (you need to turn off the power for 10 minutes).

If you hear atypical sounds (for example, relay clicks every 5 seconds), this may indicate:

• Malfunction start relay compressor.
• Short circuit in compressor winding.
• Failure control board (relevant for models with an electronic display).

Comparison of switching features of LG refrigerators of different series

Refrigerators LG are divided into several series, each of which has its own nuances of inclusion. In the table below we have collected the key differences:

If you are not sure which series your refrigerator belongs to, look at the markings on the sticker inside the chamber or on the back panel. The first two letters after LG usually indicate the series (for example, LG GB-B459...).

For models with double compressor (for example, GC-B247JLQV), each chamber is turned on separately. This is convenient if you want to save energy by turning off the freezer for the time when it is not needed.

FAQ: Answers to frequently asked questions

The LG refrigerator turns on, but immediately turns off. What is the reason?

This is a typical problem for models with inverter compressor. reasons:

• It worked overheating protection (you need to wait 10-15 minutes and turn it on again).
• Faulty starting relay (replacement required).
• Low voltage in network (check with a stabilizer).

If the problem persists, unplug the refrigerator for 1 hour, then try again. If that doesn’t help, contact the service.

Do you need to defrost the LG No Frost refrigerator before turning it on for the first time?

No, you don’t need to defrost a new refrigerator. LG No Frost However, if the equipment was stored in a warehouse at subzero temperatures, let it stand in a warm room 4-6 hours before turning it on to avoid condensation on the electronic boards.

How to turn on an LG refrigerator after replacing the compressor?

After replacement compressor:

1. Make sure that the technician has removed all the air from the system and charged the correct amount of refrigerant.
2. Connect the refrigerator to the network and wait until the compressor reaches operating pressure (this may take up to 5 minutes).
3. If the refrigerator does not turns on, check thermal relay fuse —it could have burned out during replacement.

In the first 24 hours after repair, avoid loading the refrigerator with food - let the system stabilize.

Is it possible to connect an LG refrigerator to the network via an extension cord?

No, this is not recommended. Refrigerators LG (especially those with inverter compressors) The extension cord can:

• Create additional resistance, which leads to a voltage drop.
• Overheat during prolonged operation of the compressor.
• Cause malfunctions in the electronic control unit.

If the socket is far away, use permanent installation of a new socket or surge protector with protection against power surges.

Why does the LG refrigerator make a loud noise after turning it on?

Humm in the first 1-2 days after switching on is normal, especially for new refrigerators. Possible reasons:

• The compressor operates in intensified mode to set the temperature.
• In models with No Frost you may hear the operation of fan.
• If the refrigerator is not new, a hum may indicate wear on the compressor or a lack of refrigerant.

If the noise does not go away longer 3 days or is accompanied by vibration, check:

• Evenness of installation (adjust the legs).
