LG inverter linear refrigerator not cooling

When we own an LG refrigerator, we may encounter an issue with the LG inverter linear refrigerator not cooling effectively. This type of refrigerator is designed to keep food fresh for longer periods by minimizing temperature fluctuations. It incorporates advanced technology that results in quieter operation compared to conventional compressors. This refrigerator is known for its excellent temperature control, with air vents strategically placed at the front for uniform cooling throughout the unit. Additionally, it features a high-quality air filter that aids in eliminating bacteria and unpleasant odors. The design is compact, allowing it to fit seamlessly into our designated space, and it is capable of keeping vegetables and fruits fresh for an extended time.

What is lg inverter linear refrigerator?

To understand the reasons behind an LG inverter linear refrigerator not cooling properly, it’s important to be familiar with the technology it uses. The LG inverter linear refrigerator employs advanced technology that allows for greater energy savings. While a typical digital inverter compressor operates with four friction points, the LG inverter linear compressor reduces this to just one friction point. Consequently, this reduction in friction leads to increased energy efficiency and better performance.

Why is the LG inverter linear refrigerator not cooling?

Various issues can contribute to an LG inverter linear refrigerator not cooling effectively. These are some potential causes:

Inverter failure can lead to the LG inverter linear refrigerator not cooling. This issue is common when the compressor operates without cooling the unit due to its inability to circulate refrigerant effectively.

A dirty condenser coil may impair the refrigerator’s cooling ability by restricting the rate of heat transfer from the refrigerant.

A defective condenser fan could be another culprit. Obstructions in the fan blades or issues with the condenser fan motor can hinder proper airflow.

Evaporator fan issues can also affect cooling. The evaporator fan is responsible for circulating air within the fridge. If the fan blades are obstructed or the motor is faulty, air circulation can be compromised.

It’s important to check the temperature control thermostat. If this thermostat is malfunctioning, it can lead to cooling problems as it regulates the power supplied to the control board, influencing the internal temperature of the refrigerator and freezer.

Control board failure might also be responsible for cooling issues, as it controls the power supply to the compressor, condenser fan, and evaporator fan. If the control board fails, these components won’t function as they should.

How to solve the lg inverter linear refrigerator not cooling problem 

To address the issue of an LG inverter linear refrigerator not cooling, here are several steps you can take:

If you suspect a defective inverter compressor, first unplug the refrigerator, remove the back panel, and inspect the compressor. If the compressor isn’t running, it’s best to consult with professional technicians for further diagnosis or repair.

For dirty condenser coils, clean them thoroughly. You’ll need to remove the protective cover, then gently clean the coils with a soft brush and warm soapy water. Ensure the coils are completely dry before retesting the refrigerator’s cooling function.

Inspect and clean the condenser fan blades to remove any debris that could obstruct airflow. Use a multimeter to test the condenser fan motor for continuity. If there’s an issue with the motor windings, it may need to be replaced. Contacting LG or a professional service person is advised if replacement is necessary.

To test the temperature control thermostat, use a multimeter to check for continuity or resistance changes as you adjust the thermostat to different settings. If the readings do not change, it indicates a faulty thermostat that could prevent power from reaching the temperature control board, necessitating a replacement.

If you suspect a control board problem, this often requires expertise beyond DIY solutions. It’s advisable to seek assistance from professional technicians who can diagnose and service control board issues.

How to identify the bad lg refrigerator linear compressor

When we use LG fridge we can see many signs of a bad compressor. Here is the description of them.

1. Sound 

We can identify the compressor condition by hearing the sound. We can hear a buzzing sound when the compressor works properly. If we do not hear this type of sound it will not be a good compressor. It has problems.

2. Operation

For supplying a continuous flow of air we need a good compressor. When the lg compressor is running nonstop it may be broken. On the other hand when it is not working properly it may be a bad compressor.

3. Temperature

When the compressor is running it is hot. We can feel the heat with the touch of a hand. If we feel overheated it has malfunctioned. We should be careful when we touch it with our hands.

Difference between inverter refrigerator and conventional refrigerator 

A conventional refrigerator operates at a constant speed, while an inverter refrigerator operates at variable speeds. The inverter refrigerator uses a lower amount of energy to deliver maximum efficiency.

Unlike the conventional refrigerator, which lacks flexibility, the inverter refrigerator is both flexible and adaptable.

An inverter refrigerator can save more energy compared to a conventional refrigerator.

An inverter refrigerator generates less noise than a conventional refrigerator, which tends to produce more noise.

Find the top refrigerator 66 inches tall

We can find the refrigerator 66 inches tall easily in the market. The height of most refrigerators is 62 to 72inches. When we want to buy a fridge, we can find the french door refrigerators and the side-by-side refrigerators with more height and width.


The LG inverter linear refrigerator is an excellent appliance that allows us to save both money and energy. Various models of LG refrigerators are available in the market, and choosing an inverter linear refrigerator is advisable. Although it may have a slower cooling process, it is still a worthwhile purchase. While using it, we might encounter some common problems, which we can often resolve on our own. If the issues persist and we are unable to fix them, we should reach out to professional technicians for assistance.
