Product review (5 stars): Running quite now!
Our LG is about five to six years old and the fan started making noise.  I pulled the 'fridge out to clean it up and oil what I could get to without taking apart the motor.  That worked for about a 1 1/2 days.  Then I removed the entire fan assembly, pulled out the motor and oiled it.  Put all back and it ran quite for perhaps a little over a month.  When the noise came back I ordered this part.

At first I was nervous because there was no picture and I knew what the part should look like; when I ordered, there was a picture of a similar fan motor but not the one I needed.  My model number was listed for this fan so I was just hoping I would get the right replacement part.  It was the right part and I knew as soon as I opened the box.

You can find instructions or diagrams online on how to replace the motor.  It's not has hard as you might think.  I needed a screw driver, wrench (to disconnect the water supply line) and I used needle nose pliers to help remove the fan from the shaft.  Wish I could post pictures to help buyers "see" the motor they get, but if your model number is listed then it'll most likely work for you.

Just a few minutes of work.  Once you have the back cover off, there are perhaps 3 screws to remove to get everything loose and out of the way and then there are two tabs to press down so you can slide the fan assembly out.  Then unscrew the back, remove the fan from the shaft, remove the motor and replace, reattach the fan, screw it all back together and you're done!  Maybe that's over simplifying it but it's pretty close.  The hardest part was removing and reattaching the fan - that's what I used the needle nose pliers for (again, wish I could post pictures).

Edit:  Found the link to add pictures!  Hope they help.
