LG refrigerators are some of the best on the market. However, they may break down. One of the most common problems is that the LG refrigerator not cooling properly. And that’s a problem because that’s the main job of a refrigerator!
In the modern era, the fridge is more than just a place to store your perishable food items. It’s also a place where leftovers can be stored and drinks for the family can be stocked. The most important of all kitchen appliances – it is probably larger than most others too!
This is one situation that can be really discouraging. You notice that the temperature in your LG fridge isn’t staying where it’s supposed to be. What could be wrong? Well, below are some common causes of why your LG refrigerator isn’t cooling.
Why LG Refrigerator Not Cooling – Causes And Solution
If your LG refrigerator is not cooling, there are several possible causes. First, check to make sure that the power cord is plugged into an outlet and that the refrigerator is turned on. If the power cord is not the issue, check to see if the condenser coils are dirty.
If they are, clean them with a soft brush. If the coils are not the issue, the problem may be with the evaporator fan. If the fan is not working, the refrigerator will not be able to properly circulate air and will not cool properly.
Faulty Condenser Fan Motor
LG, a well-known manufacturer of home appliances, has a cooling system that’s based on the continuous flow of cool air. One of the main parts of this is the condenser fan – it moves air across the coils which cool the air. If the airflow is obstructed or nonexistent, the problem could be that the condenser fan blades are dirty or the fan motor is broken.
Be sure to check that the power is off before you work on anything that uses power. The first step in checking is to look for any debris in the fan or around it and make sure it is turning freely. Next, you can check the motor for continuity with a multimeter to see if the problem is the motor winding. If you think the problem is in the motor, you will need to contact LG and get a replacement.
Replace the old condenser fan motor in your fridge by following these steps:
- Remove the old part.
- Install the new one
- Close up all covers and reconnect the water line if necessary.
- Plugin the power cord.
- Move the fridge back to its original place.
- Start the refrigerator and let it start cooling.
- Check the temperature.
Evaporator Fan Motor Not Working
When it comes to refrigerators, many have a single evaporator fan, which is located on the back of the freezer section. This fan cools your freezer and refrigerator sections by circulating the air across the cooling coils and into these areas. If it’s not moving enough cool air, the fridge will not keep the freezer or fridge sections cool.
Do the Following Steps to check the Evaporator Fan Motor:
- Turn off the appliance and locate the evaporator fan motor in the freezer compartment.
- If the fan is overly noisy, this is a sign that it should be replaced.
- If it isn’t noisy, turn the fan blade manually. If the blade is stuck, replace the evaporator fan motor.
- check the fan motor for continuity, If it fails then we have to replace the motor.
Here’s how to test the motor:
- Turn the blade around and check that it turns.
- Plug the motor into the multimeter and check that it has continuity. If it does, your motor is working correctly and not the cause of the problem. If the motor doesn’t have continuity, you’ll need to replace it.
Failed Inverter Linear Compressor
LG refrigerators are designed to stay cool, no matter how many compartments. But if your fridge is not cooling properly, you might be experiencing a few problems. If the fridge is warm and the freezer continues to be cold, then the problem is restricted airflow. This can be due to anything from a burnt defrost thermal fuse to a failed evaporator fan. If the fridge is warm and the freezer is warm, your faulty product might have a failed inverter linear compressor or start relay.
LG refrigerators decided to update their compressors and test them extensively for reliability. The new generations of LG refrigerators make sure to solve common problems such as failure to cool and often breaking. Listen carefully: If your refrigerator isn’t cooling at all, then you need to pull it out of its spot, remove the back panel, and see if the compressor is running.
If you hear your refrigerator running, but it’s not cooling, then it’s likely that the compressor is broken. Usually, this means that it isn’t pumping refrigerant to cool down the fridge. Fortunately, most LG compressors have a 10-year warranty. So before you do anything else, be sure to check your warranty coverage and contact LG Customer Service.
Faulty Compressor Start Relay
LG refrigerators have two important parts in the cooling system: the compressor and the start relay. When it is not working properly, it will prevent the compressor from working properly, too. To fix it, you will need to open up the back panels of your LG refrigerator to access the bottom of it.
The first step is to remove the refrigerator from the outlet. Next, if your fridge has a water line, disconnect it. Then relocate the refrigerator to gain access to the back compartment.
The start relay is located near the compressor. We will use a multimeter to see if there is continuity between the start and run terminals. If there isn’t, we will need to replace the relay.
It’s time to contact LG to find out how to replace your refrigerator’s start relay. After replacing the part, don’t forget to button it all back up and reconnect the water line if it was disconnected. Once you’ve done all that, plug the unit in and turn it on.
Dirty Condensing Coils
The condenser coils are the most important part of any refrigerator. They contain the coolant and circulate it through the coils. The coolant removes heat from the refrigerator’s air and the coils remove heat from inside the fridge.
Condenser units are important for keeping the fridge at the right temperature. If you notice that it is too hot, there might be something wrong with the condenser unit or coils may need to be cleaned. To get to your condenser unit, you’ll have to access the back of the fridge from the bottom.
If you need to move this appliance, unplug the unit and disconnect the waterline. Before you start inspecting, be sure that the unit is completely disconnected and unplugged. If coils are dirty, we would recommend that you remove any debris using a stiff brush or air hose. To remove dirt that has hardened, use a brush with soapy water or a scrubbing pad.
You should make sure everything dries before testing the LG refrigerator for cooling issues.
Defective Temperature Control Thermostat
The thermostat is one of the electrical components of the LG refrigerator. It helps control which of the three cooling components (Evaporator fan, condenser fan, and compressor) will function. If it’s not working right, one or more of these parts won’t work right.
If you think your problem is the temperature control thermostat, you’ll need to get in the back of the unit. The thermostat will be easy to find and it will be at the bottom of the unit. To tell if it is working, turn the knob and check if it clicks.
When you adjust your thermostat, you want to be sure it’s functioning correctly. This is a precautionary step to take to ensure that there are no problems with the thermostat as you turn the knob. If the thermostat is faulty, you should contact LG and order a part for your refrigerator.
Once you have a replacement part installed and everything reassembled, reconnected, and plugged in, test the unit to see if it’s working.
Replace the Main Control Board
If your refrigerator isn’t cooling properly, you might need to replace the main control board. This is rarely the cause of the problem, but it does happen. And, if you’ve tried everything else, replacing the main control board might be your best choice. However, you might be better off just buying a new fridge.
LG Fridge Making Noise Not Cooling
If your LG fridge is making noise and not cooling, there are a few potential causes.
First, check to see if the evaporator fan motor is working properly. If the fan motor is defective, it will need to be replaced.
Secondly, check the condenser coils to see if they are dirty or blocked. If the coils are dirty or blocked, they will need to be cleaned or replaced.
Finally, check the compressor to see if it is working properly. If the compressor is not working properly, it will need to be replaced.
LG Refrigerator Not Getting Cold
LG refrigerators are one of the most popular brands on the market, but like any appliance, they can sometimes have issues. If your LG fridge is not getting cold, there are a few potential reasons why.
One possibility is that the fridge is not properly plugged in. If the fridge is not plugged in or the outlet is not working, the fridge will not be able to get cold. Another possibility is that the fridge is not set to the correct temperature.
The fridge needs to be set to a colder temperature in order for it to get cold. If the fridge is properly plugged in and the temperature is set correctly, one potential issue could be the evaporator coils. These coils need to be cleaned every few months in order to prevent them from getting too frosted over and preventing cold air from circulating properly.
Another potential issue could be the condenser coils. These coils also need to be cleaned on a regular basis in order to prevent them from getting too dirty and blocking air flow.
If you have checked all of these things and your LG fridge still is not getting cold, you may need to call a repairman to come and take a look at it.
LG Fridge Not Blowing Cold Air
If your LG fridge is not blowing cold air, there could be several reasons why. Here are some potential reasons to check:
1. The fridge could be set to a warmer temperature than usual. Check the fridge temperature setting and make sure it is set to a colder setting.
2. The fridge could be in defrost mode. In defrost mode, the fridge will not blow cold air. Check your owner’s manual to see how to turn off defrost mode.
3. The fridge could be low on Freon. Freon is the gas that helps the fridge cool. If the fridge is low on Freon, it will not blow cold air. You will need to call a professional to add Freon to the fridge.
4. The fridge could have a dirty condenser coil. The condenser coil helps the fridge cool. If the coil is dirty, it will not work as well and the fridge will not blow cold air. Clean the condenser coil with a brush and vacuum.
5. The fridge could have a faulty door seal. If the door seal is not sealing properly, cold air can escape and warm air can enter. This will cause the fridge to not blow cold air. Inspect the door seal and replace it if it is damaged.
The above solutions work for all models including Lfxs29766s, Lsxs26326s, Lfxs30766d, Lmxs27626s and more.
