I am trying to access the pictorial essay on the blog post at http://fixitnow.com/wp/2010/10/02/repairing-a-water-tube-embedded-inside-the-freezer-door-foam-insulation-of-a-ge-refrigerator/, posted by the Samurai Appliance Repair Man.
I have exactly the issue described there, with a leaking in-door water service line in the refrigerator door, causing puddles when the water dispenser is used, and sputtering after the water back drains into the fridge door. The fridge is about 12 years old, a GE profile PTC22SFMALBS, and is a freezer-on-top model with the water line running through the refrigerator door, into the freezer door, and making a series of twists bent into the tubing--not a "pull through" operation as with a SxS fridge.
If I can access the water in the freezer, I can fix the issue. But with the water line embedded in foam, I am afraid that when I take the door apart, it will not be an easy process and I may ruin the insulation or the door when I do it. Hoping the video on the post referenced above will be a better solution to the problem!
Thanks!
