LG Freezer Not Freezing (Solutions)

It can be very annoying to find the LG refrigerator malfunctioning or the bottom freezer not freezing. 

We had faced a very similar problem where the LG refrigerator was running perfectly, but the freezer was not cooling enough. Hence, freezing ice cream was out of the question, which was disheartening. 

That is not all; when this happens, the ice maker stops working, and the food kept inside may deteriorate. You can try changing the freezer temperature from high to low to see if that makes any difference. Then you can try defrosting the freezer by cleaning it well.

We will discuss the defrosting process as well as the other reasons behind a LG freezer not freezing, so keep reading to know all about it. 

Why Is The LG Freezer Not Freezing? 

Before we discuss the reasons in detail, it is essential to point out fundamental issues that may interfere with the freezing process. First of all, we recommend switching off the refrigerator for a day but take all the food out of the freezer before doing this, or they will go bad. 

Then check the sealing system and the vents as well, as there should not be any cracks or gaps through which cold air can escape. Also, blocked air vents can be a reason behind improper air circulation and higher temperatures, so they need to be cleaned for better air circulation inside the freezer. 

Once you switch on the refrigerator, check the main control board to see if all the control panel lights are functioning correctly. And ensure that the fridge isn’t set to the highest temperature setting since it might disrupt the cooling. Change it to the lowest setting and check if the freezer compartment is cooling, in such a scenario. 

Reasons Behind An LG Freezer Not Freezing 

In this section, we have extensively discussed the top five reasons behind an LG freezer not freezing. 

1. Malfunctioning Start Relay 

One of the important parts of an LG freezer is the compressor, which makes the coolant pass through the cooling system. Now, this compressor is powered by the start relay, and a malfunctioning relay can cause the system to break down.

It leads to the compressor failing to perform at optimum capacity until it stops running completely. This affects the cooling capacity of the LG freezer, and it may not freeze at all even with the freezer door closed. 

If this happens to you, there are two things you can do to fix the issue. 

A. Inspection 

First of all, you can inspect the start relay to see if it has been damaged due to any reason. If you notice a burning smell, it can be because of an electrical issue. In such a case, removing and replacing the start relay is best before checking whether the LG freezer is freezing properly. 

B. Using A Multimeter

If there is no burned smell, you may need to look into the issue more closely. To do this, take the help of a multimeter and use it to verify if the start relay is functioning correctly and whether there is power continuity. 

A malfunctioning start relay will not allow electricity to pass through, which you can detect with a multimeter. If you see there is no sign of electricity flowing through the component, take the start relay out and replace it with a new one. 

2. Dirty Condenser Coils 

Now that you know all about how to fix the start relay, we move on to the condenser coils. You should know that the refrigerant absorbs heat and then it flows through the fridge’s cooling system. But the condenser coils are in their way, and the heat-laden refrigerant passes over the coils. 

If you touch these condenser coils, you will find that they are very hot. That is because they are responsible for releasing heat into the surrounding air from the freezer. 

You will also find a condenser fan motor that helps in moving the air past the coils for the heat to escape the unit. But if your freezer has a dirty condenser coil or a defective condenser fan motor, it will not be able to transfer the heat. 

The condenser coils can easily get dirty over time as dust accumulates on them. This slows down the process of transferring heat to the outside air, and when this happens, you will find that the freezer is not cooling properly. 

But the good news is that you can quickly take care of this with a good vacuum and a soft brush. The vacuum has to be used first to clean away all the debris and loose dust that has collected on the condenser coils. After that, you can remove any remaining dirt, which is stuck on these coils with the brush. 

Once thoroughly cleaned, check the efficiency of the freezer to determine if it is cooling well. 

3. Temperature Control Thermostat

You need to check the LG freezer’s thermostat to detect freezing issues. The best way to go about it is to find more information about the thermostat in the user manual or sheets provided with the package. Note that this part may also be referred to as the thermistor, so don’t get confused, and it is responsible for measuring the internal temperature of the freezer. 

If the temperature control thermostat is working properly, the temperature control board will sense when the cooling process needs to stop or start. But a malfunctioning thermostat will not be able to detect the right temperature. 

Hence, your refrigerator may incorrectly read that it has reached freezing temperatures, when it has not. The sad part is that the temperature control thermostat cannot be repaired, and it has to be replaced.

But before doing so, confirm if the temperature control sensor is working properly with the help of a multimeter. If the multimeter does not show electrical continuity, the thermostat will definitely need to be replaced. Once that is done, the freezer temperature can be checked to see if it is working fine. 

4. Cold Evaporator Coils 

You have already learned about the condenser coils above, and now it is time to know about the other set, which is the evaporator coils.

Two freezer evaporator coils are present in the LG freezer’s cooling system. These components are part of the cooler section of the freezer and are present inside the unit. They reduce the air temperature inside the LG freezer compartment to keep your food items safe and fresh. 

However, if there is ice or frost buildup inside the freezer, on the freezer walls, and around the evaporator coils, it could hamper the cold airflow. That would mean higher temperatures, and the freezer may not be able to freeze food items effectively. 

LG freezers are also programmed to drive an automatic defrost cycle once or twice a day. The defrost system is supposed to ensure that the frost melts and is removed to prevent further complications. 

But if you find that the evaporator coils are covered with ice, that means the defrost cycle is not working well. To fix this issue, you will have to switch off the freezer and defrost it manually. 

Once you have removed all the melted frost and ice, the defrost system needs troubleshooting to ensure that it runs normally.  If you cannot do this on your own, call LG customer care and ask for help; they send professionals to fix this issue in a jiffy. 

5. Malfunctioning Evaporator Fan Motor 

Now that you know about the evaporator coils let us tell you that they do not function on their own. Instead, there is an evaporator fan motor that helps in cooling while it also distributes cool air throughout the freezer. 

If you have been using an LG refrigerator for a long time, the evaporator fan motor may malfunction due to old age, as it has worn out. It can even happen when there is a sudden power surge or a short circuit that damages the system. 

If the motor fails, you will need to replace it with a new one. You may be wondering if the motor can be repaired but we believe that it is not going to be a practical and cost-effective solution. Instead, just get a new motor that can last for a few years. 

FAQs

Can a power outage lead to a malfunctioning cooling system? 

If there are sudden power surges during a power outage, the fuse may be burned, which can damage the freezer or the entire refrigerator. You will need to call professionals to fix this when you notice a burning smell. 

Otherwise, you can check the wall socket to see if the fridge is getting the necessary voltage supply. If the power outlet is fine, check the power cord to see whether it has burned or not because in case it has, you will need to get it replaced.

Another option for restoring the cooling system is leaving the refrigerator unplugged for about 30 seconds. Then, turn off the circuit breaker and reset the freezer using the freezer door switch. 

How to reset the temperature of the freezer? 

Resetting the temperature of the freezer is pretty easy. You will find a lock button on the control board and on pressing it, the control panel will be unlocked. Proceed to press the freezer button several times to bring down the temperature and after you are done, remember to shut the freezer door properly. 

If there are kids in the house, teach them the importance of closing this door well; otherwise, all the food items inside can go bad. 

What to do when the freezer cools but does not freeze food items?

If you notice the freezer cooling but not being able to freeze food items, there might be a problem with the condenser coils. These coils are responsible for removing heat from the LG freezer and dispersing it into the surrounding air. 

When the coils are dirty, it’s essential to clean them well to ensure that they function properly for the freezer to work at optimum capacity. Once they are cleaned, switch on the LG refrigerator and check the display board to see if it is set on a cold temperature setting. Reduce it further if needed, and your freezer should work well.

Can an LG freezer be defrosted without switching it off? 

You can defrost the freezer while it is plugged in and all you need to do is use a big container of boiling water. Place it inside the freezer compartment and close the door.

Leave it for some time until the water cools down before you repeat the process with more hot water to slowly melt the frost buildup inside the compartment. Once the frost is removed, the freezer can cool better while ensuring that the evaporator fan blades turn freely for proper movement of cold air.

LG Freezer Not Freezing Ice Cream

If your LG freezer is not freezing ice cream, it could be due to a number of reasons. The first step is to check the temperature settings on the freezer. Make sure that the temperature is set low enough to properly freeze ice cream.

If the temperature is set correctly and the issue persists, it could be due to a clogged or dirty condenser coil. This can be easily cleaned with a brush or vacuum. Another potential issue could be a malfunctioning thermostat or compressor.

This is best left to a professional to diagnose and repair. In any case, it’s important to address the problem quickly to avoid any further damage or food spoilage.

Final Words 

Once you have worked out the issue, you can reset the LG refrigerator to check if it starts cooling. To do so, you will need to press the Ice Plus and Refrigerator buttons on the door trim for five seconds. You should hear a sound from the control panel that indicates the machine has been reset.

Also, we will recommend cleaning the entire LG refrigerator once in a while to ensure cold air can circulate well. Manually defrost the freezer compartment, and you can even use a vacuum cleaner to clean the coils. 

This should keep all the components working well, and the coils should dissipate heat effectively. And while you are at it, inspect and clean the evaporator fan and the condenser fan, along with the air vents. We hope you will now be able to fix any issue quickly or you can always call up customer care for help. 

Bye!
