Why is LG Refrigerator Not Cooling?

1. Condenser Fan Motor.

One of the most important parts of your refrigerator, the condenser fan motor circulates air through the coils to keep them cool.

If this motor stops working, your fridge will no longer be able to properly cool food.

Why does it fail?

The most common reason for the condenser fan motor to fail is because of a buildup of dust and dirt on the blades. This can happen over time, and will eventually cause the motor to overheat and fail.

Another common reason for this failure is because of a problem with the electrical connection to the motor. If the connection is loose or damaged, it can cause the motor to fail.

What are the symptoms?

The most common symptom of a problem with the condenser fan motor is that the fridge will not be able to maintain a consistent temperature.

The fridge may also make a humming noise when the compressor is running. If you think there may be a problem with the condenser fan motor, it is important to have it checked out by a qualified fridge repair technician.

How do you fix it?

If the condenser fan motor has failed, the best way to fix it is to replace it with a new one. This can be done by a qualified fridge repair technician. They will also be able to check for any other potential problems with the fridge that may need to be fixed.

2. Evaporator Fan Motor.

If your LG refrigerator is not cooling, the evaporator fan motor could be to blame. This part circulates air over the evaporator coils to help remove heat and moisture from the fridge.

If it’s not working properly, your fridge will struggle to keep things cool. You can test the evaporator fan motor with a multimeter to see if it’s receiving power.

If it is, then the problem may be with the motor itself and you’ll need to replace it.

If your evaporator fan motor is not working properly, it may be due to a faulty connection. Check the wires leading to the motor to see if they are loose or damaged. If so, you’ll need to replace them.

Another possibility is that the evaporator fan motor is simply not getting enough power. Make sure that the fridge is plugged into a working outlet and that the circuit breaker hasn’t tripped. If everything looks to be in working order, then you may need to replace the evaporator fan motor.

Replacing the evaporator fan motor is a fairly simple process. You’ll need to remove the back panel of your fridge to access the motor.

Once you have the old motor out, simply disconnect the wires and connect them to the new motor. Then, replace the back panel and screw it in place. With that, your fridge should be up and running again!

3. Inverter Linear Compressor.

The most common issue with LG refrigerators is that the fridge is not cooling properly. This usually happens because the inverter linear compressor has failed.

The inverter linear compressor is responsible for regulating the flow of coolant in the fridge. When it fails, the coolant does not flow properly and the fridge cannot maintain a consistent temperature.

Why does it fail?

There are several reasons why the inverter linear compressor in an LG refrigerator might fail. One reason is that the fridge is not properly ventilated.

If there isn’t enough airflow around the fridge, then the compressor can overheat and shut down.

4. Compressor.

The compressor is the part of the fridge that makes the cool air. If the compressor isn’t working, then the fridge won’t be able to make cold air. The most common cause of a compressor not working is a blown fuse.

Why does it fail?

There are several reasons your LG refrigerator might not be cooling properly. One reason could be that the compressor is not working correctly.

The compressor is responsible for circulating coolant throughout the fridge, so if it’s not working properly, the entire fridge will suffer.

Another possible reason is that the evaporator coils are frosted over. This prevents cold air from properly circulating, and can cause the fridge to become too warm.

Finally, if the door seal is damaged or broken, cold air can escape and warm air can enter, causing the fridge to become too warm.

How to fix it?

If the compressor is the problem, you’ll need to call a repairman to fix it.

If the evaporator coils are frosted over, you can try defrosting them yourself by unplugging the fridge and letting it sit for a few hours.

However, if the door seal is damaged, you’ll need to replace it. You can buy replacement door seals at most hardware stores.

5. Start Relay.

If your refrigerator is not cooling, one of the first things to check is the start relay. The start relay’s job is to give the compressor an initial burst of power when it starts up. If the start relay is bad, the compressor won’t be able to turn on.

To test the start relay, first unplug your fridge and then remove the start relay from the back of the fridge. Next, use a multimeter to test the start relay for continuity. If there is no continuity, then the start relay needs to be replaced.

Why does it fail?

The most common reason for a start relay to fail is because of a dirty or clogged filter. A dirty filter can cause the fridge to overheat and the compressor to shut down.

If this happens, the fridge will not be able to cool properly. To clean the filter, simply remove it and rinse it off with water.

6. Temperature Control Thermostat.

If your fridge isn’t cooling properly, one potential issue could be the temperature control thermostat.

This part regulates the temperature inside the fridge, so if it’s not working correctly, it can cause the fridge to be too cold or too warm.
