The Refrigerator now runs very quite.
After watching several videos I started on mine and found that it was a bit different than any in the videos. However all but the back panel was shown and that was helpful.
The back panel was a bit difficult but a hair dryer seemed to help .
All in all it was a good choice to do it myself as it was done quicker than waiting on a repair man.

Examined old ice maker. It is held by some Philips screws. There are many screws you don't need to unscrew so look carefully. Then disconnected th dual in line connector. There is a little push tab to squeeze to release. Then the ground is connected with a screw. It's a little hard to see but unscrew that. My replacement came with no instructions or screws so try not to drop the screws down in the netherlands of the fridge. The hardest part was maneuvering the icemaker to reattach the power and ground. Even with that pretty straight forward replacement.

I actually watched a YouTube video for LG refrigerators. The hardest part was taking the wire harness out. Mine was really stuck in there. But got it, put the new switch in and viola it worked. Yay!

followed detailed movie from Utube video

took out original Duct Assembly, put in NEW Duct Assembly the same way the original Duct Assembly was removed in the freezer. The rest was easy to put back together

Have your wonderful Grandson do the repair work.

Go to this site on You Tube to watch the "how to" replace the gasket retainer. The retainer I needed did not come with brackets or the cam you will need. You will need transfer them from the old retainer to the new one. Not hard, just be mindful of position of the items you remove to put them back in place the same way. A metal rod holds the brackets and spring in place with a screw on one end to prevent rod from sliding off retainer. The cam has a screw that holds it in place, use from old retainer. If the old cam is not broken use the one from the old retainer. It is not hard and you will save $$$ that you would pay an appliance repair company.

It's a snap in part. 10 seconds to install

My husband took out the ice maker. We ordered the part. He looked on YouTube for instructions. Including looking up instructions, I think it took him way less than an hour.
