If you’re experiencing issues with your LG refrigerator, one of the most common problems is a fan that isn’t running.
If the fan stops, the temperature of the refrigerator will rise and the compressor may overheat. Eventually, the food may spoil.
One possible reason for the fan not running is a faulty evaporator fan motor.
This motor is responsible for circulating air throughout the fridge and freezer compartments.
If it’s not working properly, you’ll notice that the fridge isn’t cooling as it should.
Another possible cause is a malfunctioning control board, which regulates the fan’s operation.
Common Reasons Why LG Refrigerator Fan Is Not Running
If you notice that your LG refrigerator fan is not running, there could be several reasons why. Here are some common causes that could be behind the problem:
- Faulty Evaporator Fan Motor
The evaporator fan motor is responsible for circulating air across the cooling coils and into the freezer and refrigerator sections. If this fan motor is faulty, it can result in poor cooling performance and cause the fan to stop running.
- Blocked Airflow
If there is a blockage in the air vents, it can restrict the flow of air and cause the fan to stop running. This can happen if the vents become clogged with ice or debris.
- Defective Control Board
The control board is responsible for controlling the functions of the refrigerator, including the fan motor. If the control board is defective, it can cause the fan to stop running.
- Damaged Fan Blade
If the fan blade is damaged, it can cause the fan to stop running or make unusual noises. This can happen if the blade becomes bent or warped over time.
- Faulty Temperature Sensor
The temperature sensor is responsible for monitoring the temperature inside the refrigerator and sending signals to the control board. If the sensor is faulty, it can cause the fan to stop running or cause other cooling problems.
- Worn Out Fan Motor Bearings
Over time, the bearings in the fan motor can wear out and cause the fan to stop running. This can happen if the fan motor is not lubricated regularly.
How to Fix LG Refrigerator Fan Not Running
While experiencing the fan not running issue on your LG Refrigerator, here are some steps you can take to try and fix the problem:
Check the Power Supply
Make sure the refrigerator is plugged in and the outlet is working. If the outlet is not working, try plugging the refrigerator into a different outlet.
If the refrigerator is still not working, unplug it and check the power cord for any damage.
Inspect the Fan Blades
Look at the fan blades to make sure they are not obstructed by any debris or ice. If there is any debris or ice, remove it carefully.
Be sure to unplug the refrigerator before attempting to remove any debris or ice.
Test the Fan Motor
If the fan blades are not obstructed, you can test the fan motor to see if it is working properly. You can do this by using a multimeter to check the resistance of the motor.
If the resistance is outside the normal range, you may need to replace the fan motor.
Check the Capacitor
The capacitor is a small device that helps to start the fan motor. If the capacitor is not working properly, the fan motor may not start.
You can test the capacitor using a multimeter to check the resistance. If the resistance is outside the normal range, it may be time to replace your fridge capacitor.
Inspect the Thermostat
The thermostat is responsible for regulating the temperature inside the refrigerator. If the thermostat is not working properly, it may not be sending the signal to start the fan motor.
You can test the thermostat using a multimeter to check the resistance. If the resistance is outside the normal range, you may need to replace the thermostat.
These are some of the steps you can take to troubleshoot a non-running fan in your LG refrigerator.
If you are not comfortable performing these steps yourself, you may want to consider calling a professional for assistance.
When to Contact a Professional
If you have gone through all the troubleshooting steps and your LG refrigerator fan is still not running, it may be time to contact a professional.
Here are some situations where you may want to consider calling in an expert:
- You are not comfortable working with electrical components
If you are not familiar with electrical wiring, it is best to leave repairs to a professional.
Attempting to fix the fan motor or capacitor without proper knowledge and training can be dangerous and may cause further damage to your fridge.
- The fan motor needs to be replaced
If you have tested the fan motor and found that it needs to be replaced, it is best to have a professional handle the job.
They can ensure that the motor is installed correctly and that all wiring is properly connected.
- The thermostat needs to be replaced
If you have determined that the thermostat is the cause of the problem, it is best to have a professional replace it. They can ensure that the new thermostat is properly calibrated and installed.
- You have tried all troubleshooting steps and the fan still won’t run
If you have gone through all the troubleshooting steps and the fan is still not running, it may be time to call in a professional.
They can diagnose the problem and provide a solution that will get your fridge up and running again.
Preventive Measures to Keep Your LG Refrigerator Fan Running
To avoid your LG refrigerator fan from not running, you can take some preventive measures. Here are some tips that can help you keep your refrigerator fan running smoothly:
Clean the condenser coils
Dirty condenser coils can cause your refrigerator fan to work harder than it should, which can stop it from running.
Make sure to clean the condenser coils regularly to prevent this issue. You can use a narrow hose vacuum attachment to remove dust and debris from the coils.
Check the thermostat
If your refrigerator is not cooling properly, it can cause the fan to stop running.
Check the thermostat setting to ensure that it is at the recommended temperature of 37°F for the refrigerator and 0℉ for the freezer.
Avoid overloading the refrigerator
Overloading the refrigerator can stop the fan from working harder than it should, leading to it not running. Make sure to avoid overloading your refrigerator and keep it organized.
Ensure proper ventilation
Proper ventilation is important for your refrigerator to work efficiently. Make sure to leave enough space between the refrigerator and the wall to allow for proper ventilation.
Regular maintenance
Regular maintenance can help prevent issues with your refrigerator fan.
Make sure to perform routine maintenance tasks such as cleaning the condenser coils and checking the thermostat setting.
