How to Troubleshoot & Replace Lg AP4629560 / 4004JA3002A Clip

Replaced tubing and fitting 

Replaced one hose and union with clip. 

Ordered replacement assembly. Part ended up in middle of state before finally arriving at my home. Hardest part of repair was to remove food and refrigerator to do the work. I had watched videos which were pretty horrible. I was able to make it very simple by shutting off water, draining line and disconnecting everything in back. Then removed assembly and pulled out of refrigerator. The replacement part was easy to put in just be careful of the hook area, slide easy no force or you may break a part. No force needed in any part of assembly or disassembly. Put your screws and tubing clips in a couple of bags or wrap up in something. 1 screw is a little different than the others. everything works great. Took my time. 

The video was helpful in showing where the line went after entering the refrigerator. Once inside the door, instead of finding a detachable reservoir, I found a tightly wound coil of plastic tubing, all one piece with the leaking tubing. I needed to stop the repair, reassemble the door, and determine how to install the new tubing properly. Ended up cutting the tubing as far from the coil as I could get, then fished the new line to the coil. Connected the two with the 90 degree connector. It works. What might have helped: 1. directions for the coil-reservoir model 2. when searching for a 180 degree 1/4" John Guest union, I was shown pages and pages of things that were NOT John Guest unions. Your search engine seems to be indiscriminate at times. 

Purchased a new connection and clips to join the water lines together. 

The You Tube APP prepared was great help. The repair took about 45 minutes including cleaning the condenser coils. You may not need new retainer clips for the plumbing fittings as they do not deteriorate over time. Thanks for the speedy service and shipping!
