Lg MJU62070603 Water Supply Line OEM Part

First, water and electricity don't mix, so make sure to unplug your refrigerator before beginning this repair - it shouldn't take more than an hour, so you shouldn't have to worry about spoilage. My water dispenser began making a hissing sound from the back of the fridge when you pressed the dispenser. Upon inspection, I discovered the 1/4" feed line into the filter housing assembly had cracked. I ordered the 1/4" feed and 5/16" return lines, figuring to replace the return line while I was back there. In order to replace them, you have to remove main water supply line in order to remove the bib from the bottom-rear of the refrigerator to access the water manifold/valve assembly. You also must remove the filter housing assembly from the ceiling of the refrigerator, which is held in place by a single screw and some locking tabs. You will release a small amount of water, so have a towel or two handy. A small black retaining clip can be found near where the tube enters the valve body located in the bottom of the fridge. A similar retaining clip is in the ingress side of the filter socket. Removing those clips will allow you to press in on the retention bushing, which allows you to remove the tubes from the bushings. Once the split tube was removed, I pressed the ends of the replacement tube(s) into their respective bushings until they would insert no further and replaced the retention clips, being careful to not crimp the new lines. Note: there is not a lot of room in and around the area of the water manifold. You may need to remove the manifold by taking out the single screw and sliding it up about 1/8" to free the flange that helps hold it in place and disconnecting the power supply connectors to the manifold. That will give you a little more wiggle room, but the hose connected on the end nearest the front of the refrigerator is the supply to the water dispenser. If you must disconnect that line, make sure to run the dispenser first to empty out as much water as you can. Otherwise, you'll end up with a few more cups of water on the floor as the coiled line inside the door will have enough gravity pressure to empty itself onto your working surface.

Followed Instructions by other customer that had the same issue. Actual repair took about 30 minutes and cost about $12.00

We replaced the leaking tubing with tubing that Appliance Parts supplied. We had our contractor do these repairs. He always uses Appliance Parts

Replaced all external water tubes.

I replaced both hoses at the same time took around 30-45 min with getting my tools and all. Looked at Y-TUBE video to make sure I didn't miss something went smooth. Very easy.
