I got my LG refrigerator last week and every since I plugged it in a motor/ fan keeps running. Know the noise has gotten louder. Any idea what might be going on?

Here is a video to show you how to test the compressor.

Refrigerators are not the most complicated appliance in the house, but it still takes a lot of parts working together perfectly to keep your food cold. If one of those parts breaks down, or begins to, you may start to hear new noises from your refrigerator. Fridges make some noise during regular operation, but if it suddenly gets louder or makes a different noise, it is a good sign that something is wrong.

Freezer Fan
Freezers can be located on either side of the refrigerator, or may be at the top or the bottom of the unit. If you hear a noise coming from the area in which the freezer is located, you should open the freezer and see if the noise gets louder. Any squealing sounds coming from this area indicate a broken freezer fan. These units are not designed to be repaired, and eventually one making a loud noise will break and need replacement.

Condenser Fan
All motors typically require a fan in order to maintain a safe operating temperature. Like the fan in the freezer, the fan that runs on the condenser can also break down and create a similar squealing noise. The location of the fan noise is what differentiates the freezer and condenser fan problems. If you hear a fan noise coming from the lower part of the fridge at the rear, it is likely the condenser fan causing the problem.

Action to do
Open the freezer to see if the noise gets louder. If the noise becomes louder with the freezer open, the noise is likely caused by the evaporator fan. If the evaporator fan is the culprit, replace it to get rid of the noise.

Pull the refrigerator away from the wall, and check the condenser fan at the back of the fridge. A metal panel may cover the fan, which can be unscrewed. Listen to see if the fan is the source of the noise. If it is, the fan may need to be cleaned or replaced.

Thanks for using FixYa.

Good day ! : )

Good day,
On models with 2 compressors the condenser fan motor runs 24/7. It must since the compressors run randomly and that motor must be on since it handles both units.

Fan noise is subjective. It itself makes little noise but the blade does. If for example the blade was changed from the nylon style to a metal blade (good idea) then it would be somewhat louder.
If the noise is not objectionable then I would use it as is.

I would change the fan instead of buying a new one. God Bless.

Good day,
The only moving part in the freezer is the fan motor. Unless the fan blade broke one of it's blades you will need to replace the motor with a new one. They are not repairable. At the same time buy a new blade as well, since an out of balance blade could have started this problem.
To access the motor, remove the ice maker, if it has one (3 screws and an electrical plug. The cube tray holder if not).
Remove the screws from the back panel, and remove the panel.
The motor change is a straight nuts and bolts job and fairly easy.

Any decent sized appliance parts house will carry the motor and blade. Take the model number with you.

Hello, Self-defrosting refrigerators use a circulating fan to move air through the freezer and refrigerator compartment. This fan runs when ever the unit is cooling. The fan is located in the freezer, as follows:

• If the freezer is on top, the fan is on the back wall,near the top or bottom, in the center of the freezer.
• If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.
• If the freezer is on the left, the fan is on the back wall, half way up or near the top.

Overtime the fan may become noisy, usually making a chirping or squealing sound, though it may make a loud groaning noise instead.
To find out if the fan is causing the noise,just open the freezer door and push in any fan/light switches, if the noise is louder when the door is open, the evaporator fan motor is the cause. You can lubricate or repair this motor. You must replace it.
There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor(if self-defrosting), or the defrost timer (if self-defrosting).
Thanks

Problems not related.  The first is most likely the fan, or possibly water dripping on to the fan and freezing, but usually the noise comes from the fan struggling to run.  The cube problem could be as simple as the ice dispenser being put back in wrong.  There is a metal lever under the ice tray that switches between crushed and cubed.  Make sure it is seated properly.

If the refrigerator was closed for a while before plugging the power back in moisture that was left inside the refrigerator will cause the evaporator fan motor will rust on the ends of its shaft. I don't believe the motor is going bad. Usually when that happens they will run for a while and stop or just stop completely.Sea Breeze.

The run capacitor on the main wash motor needs replacing. Eventually it will just hum and overheat instead of rotating, so better replace it now before it overheats.

I doubt you can acces it easily yourself, as it may be away from the motor, and have to be tracked down.

take the cover off the fan in the freezer section and see if the fan blade is loose or hitting ice the blade just pushes on make sure the mountings are tight its probably the blade but you might need to replace the motor if i reamber correctly on the cover there is a screw at the bottom you remove then slide the cover up and its on hooks plastic hooks built on the cover ok
