LG Freezer Not Freezing: 6 Reasons & Fixes

If you meet the problem of LG freezer not freezing, this guide will tell you exactly what you need to do to fix it.

Items are supposed to be kept in below-freezing temperatures inside an LG freezer. Therefore, if it fails to do that, it behaves exactly like a regular refrigerator.

We’ll examine those five most likely causes of your LG freezer not freezing in this short guide. You’ll also learn how to solve this issue.

Why is LG Freezer Not Freezing? 6 Reasons

Here are the most common reasons we collect.

1. Dirty Condenser Coils

Condenser coils are used to condense the refrigerant as it travels through the freezer’s cooling system and absorbs heat. These coils are located on the outside of the appliance and are extremely hot.

This is because heat from the freezer is transferred to the surrounding air through the condenser coils. Typically, most freezers also have a condenser fan that drives air past the coils to help make the heat transfer process more efficient.

Unfortunately, that process becomes less effective when the condenser coils get dirty. The coils will eventually accumulate dust that prevents them from heating the air around them over an extended period of time.

When that occurs, the freezer is unable to cool down as effectively as it should. If the situation is severe, nothing inside the compartment will freeze.

Fortunately, there is a very simple solution to this issue. Using a brush and a vacuum, you must clean the soiled condenser coils. Here’s what you’ll need to do:

• Clean the area around the soiled condenser coils by first vacuuming up all loose dirt and debris.
• After that, remove any tenacious dirt that has stuck to the condenser coils with a brush.

Once you’ve done that, the freezer will start to cool and its contents will start to freeze because the heat transfer process will be effective once more.

2. Frosted Evaporator Coils

Your LG freezer’s cooling system utilizes two sets of coils in a closed loop.

Condenser coils, which get hot and radiate heat into the environment around the appliance, were covered in the previous section.

Now, we’re looking at the other set of coils: the evaporator coils, which represent the cold side of the freezer’s cooling system. These coils, which are located inside the freezer compartment, are in charge of reducing the temperature there.

Unfortunately, these evaporator coils won’t work correctly if they suffer frost and ice buildup. These accumulations will obstruct the cold air’s ability to flow smoothly and endanger the freezer’s ability to cool.

LG freezers are designed to run a defrost cycle automatically once or more times each day. Any frost buildup will be removed by these cycles before it becomes a serious issue.

However, if the evaporator coils in your freezer are covered in frost, the defrost cycle is not functioning properly.

You need to manually defrost the freezer first in order to fix this problem. Once all of the ice and frost has melted away, you can inspect the defrost system to make sure it functions as it should.

4. Failed Evaporator Fan Motor

The evaporator coils do not operate independently. The evaporator fan, which propels air past the coils, is what they use instead. In doing so, the fan helps the freezer cool down by distributing cold air evenly throughout the compartment.

After using the freezer for a while, the evaporator fan motor may stop working. That might occur as a result of a power surge or a short circuit.

However, if the motor wears out too much, the same thing might also occur. However, if you have used your LG freezer for a long time, excessive wear is only likely to occur.

The motor needs to be replaced, regardless of what caused it to malfunction. Fan motors can’t really be repaired, so the fastest course of action is to take it out and replace it.

4. Faulty Start Relay

So far, we’ve done troubleshooting on two sections of your LG freezer’s cooling system: the condenser and evaporator coils. The compressor, which moves coolant through the cooling system, is another crucial component of that system.

5. Connect With An Appliance Repair Tech

The “start relay” is a part that supplies power to the compressor. So, when that relay is faulty, the compressor will run intermittently or not run at all. As a result, your LG freezer is unable to cool and will not freeze any of the items you place inside.

The start relay should be examined after you have eliminated causes #1 through #3 above. There are two methods you can use to do that:

• Manual inspection: To begin with, look for any obvious signs of damage on the start relay. An electrically damaged relay will appear burned and smell burned. Therefore, you should change the start relay right away if you notice those symptoms.
• With a multimeter: Use a multimeter to test the start relay’s continuity for a more thorough inspection. An inoperative relay prevents electricity from passing through it (i.e., it won’t have continuity). When your multimeter test shows that to be the case, it’s time to switch out the start relay for a new one.

6. Thermostat Or Thermistor

Checking the thermostat on your LG freezer should be the last step in your troubleshooting process. This component is occasionally referred to as the thermistor in technical sheets and user manuals. Whatever name you give it, it serves the same purpose, which is to gauge the freezer’s internal temperature.

The freezer control board will receive information from the thermostat about when to begin or stop the cooling process when it is operating properly. A broken thermostat, however, won’t be able to do that precisely.

So, what happens is that the freezer mistakenly thinks that it’s cold, even when it’s not. The freezer remains warm as a result of the appliance’s failure to operate its cooling system.

Another element that you cannot repair is the thermostat or thermistor. You will need to swap it out for a new one.

Much like other electrical and electronic components, you can test the thermistor with a multimeter to confirm that it’s no longer working. You can be sure that it’s time to replace the thermostat when the multimeter indicates no longer having electrical continuity in the thermostat.

What to Do If LG Freezer Not Freezing?

Here are some solutions to the LG freezer not freezing issue.

Step 1. Clean the Condenser Coils

Cleaning the condenser coils is the simplest way to make your LG freezer functional once more. When refrigerant passes through the condenser coils, heat is released, keeping your freezer cool. Your freezer may not operate properly if they are covered in dust or frost.

You can clean the condenser coils easily by following these steps:

1. As you pull it away from the wall, turn off your freezer.
2. Find the condenser coil cover and take it off.
3. Examine the condenser coils for dust or frost once you have access to them. If they are covered in frost, let them defrost before cleaning them. Use a damp cloth or a vacuum cleaner to thoroughly clean them if they are dusted.
4. Recover the cover after cleaning, then re-start your refrigerator.
5. Check to see if your LG freezer is cooling down properly after a few hours. Step 2 should be taken if not.

Step 2. Test the Temperature Control Thermostat

The temperature control thermostat’s job is to gauge the freezer’s temperature and relay that reading to the main control board so that it can instruct other freezer parts to turn on and off. Your LG freezer won’t get cold enough when it breaks down.

This is how you can test the temperature control thermostat:

1. The temperature control thermostat is located inside the freezer door.
2. At first, set the thermostat to the lowest setting it will go, and then raise it to the highest level. When you turn it past the temperature that is currently in your freezer, you should hear a click. If not, it is defective and must be replaced.
3. Whether or not you hear a click, it is a good idea to check the thermostat for continuity with a multimeter.
4. Replace the thermostat if the test yields no continuity. The thermostat is operational and you can proceed to the following step if the test reveals continuity.

Step 3. Test the Condenser Fan

The LG freezer’s condenser fan needs to be checked next. The condenser coils are cooled off by this fan. Your freezer might not cool down to the proper temperature if it develops a fault.

This is how you can test the condenser fan:

1. Turn off the electricity to your LG freezer.
2. The back panel can be accessed by pulling the freezer away from the wall.
3. The fan should be located, so remove the cover.
4. In order to see if anything is blocking the fan, try turning it manually to start.
5. Remove anything that’s blocking the fan if it’s being blocked.
6. After that, unplug the fan motor and check its continuity with a multimeter.
7. Condenser fan unit will need to be completely replaced if the motor doesn’t have continuity. The next step can be taken if the motor is operating properly.
8. Check to see if your LG freezer can now reach the proper temperature after a new fan unit has been installed. Proceed to the following step if not.

Step 4. Test the Start Relay

To make sure the compressor can run, the start relay cooperates with the start winding. Your LG freezer won’t remain cold enough if the start relay stops functioning.

This is how you can test the start relay:

1. Turn off the electricity to your LG freezer.
2. Identify the start relay. Consult your user manual if you’re uncertain where it is.
3. Check for continuity after disconnecting the start relay with a multimeter.
4. It will be necessary to replace the start relay if there is no continuity. Continue to the next step if the start relay is operating properly.
5. Check to see if your LG freezer can now cool down to the proper temperature after installing a start relay. If not, proceed to the next phase.

Step 5. Test the Compressor

Your refrigerator and freezer need refrigerant to stay cold, which the compressor compresses and distributes through the condenser coils. Your LG freezer won’t stay cool enough if the compressor isn’t working properly.

This is how you can test the compressor:

1. Your LG freezer should be powered off.
2. the compressor’s location. Consult your user manual if you’re unsure of its location.
3. Check the continuity of the compressor with your multimeter. The probes can be used for this by putting them on the electrical pins on the compressor’s side.
4. If the test reveals that the compressor has an open circuit, it is defective and must be replaced. If the test doesn’t reveal an open circuit, the compressor is functioning properly, and you can proceed to the following step.
5. You can now choose whether to buy a new freezer or replace the compressor. If you choose to replace the compressor, you must make sure that after it is installed, your freezer starts to function properly once more. The main control board replacement (see below) is your only remaining choice if that doesn’t work.

Step 6. Replace the Main Control Board

To replace the main control board is the final step (and your only remaining choice). Since there is no assurance that this will solve the issue, it can be risky. A new freezer could be your alternative choice.

What is the Ideal Temperature for LG Freezer?

Between 0 and -18 degrees Celsius is the ideal temperature range for an LG freezer. The fridge may break down if something is placed either below or above this range. It is best to refer to the owner’s manual if you are unsure of the freezer’s recommended temperature setting.

You should bear a few things in mind when adjusting the temperature on your LG refrigerator. Initially, confirm that the refrigerator is in the appropriate mode. Each of the two modes, cooling and freezing, has a specific ideal temperature range.

Second, use the built-in thermometer to monitor the fridge’s internal temperature. By doing this, you can make sure that the refrigerator is keeping the right temperature.

Last but not least, keep in mind that the ideal temperature for an LG freezer may vary depending on the type of refrigerator you own. For more detailed information, refer to your owner’s manual.
