Water and ice will not dispense (by 3 users)

1) Get the drawing and parts list:
- Go to http://www.geappliances.com/ and navigate to "Parts & Accessories"
- Put in your model number, search for it, and select it
- Go to the "Sealed System & Mother Board" section, where you will find parts and an exploded drawing of the back of your refrigerator

2) Get dirty with a helper
- Pull out the refrigerator and locate the valve assembly
- Have someone press the unit for water and watch/confirm that you don't have a leak there.
- If so, locate the leak and replace the bad tubing or other part.
- If not, unplug each hose from the valve assembly and make sure its working. (Water goes in and then probably out two separate hoses to the water and ice dispensers.) Then trace from there to find the problem. (The water dispenser hose probably goes in the cabinet to a cold water tank and from there in to the door.)

I have the same model frig and same problem. I had Sears come out to look at it. They said it was the water valve and with parts & labor it would be $298.00. Once he replaced the water valve, it still didn't work and then he thought the waterline might be freezing inside the door. The only thing they recommended was replacing the whole door for $800.00. Yeah right, I'd buy a new frig before I did that and it sure wouldn't be a GE. After reading some blogs, I discovered many people have the same problem with GE. GE tried to get the water cold by putting it through the freezer but if it isn't used for awhile, it can freeze up. Some recommended turning off the freezer for 5 hrs or so and it would melt and would work again. Some recommended putting a line of weedeater line through the waterline or drying with hair dryer which can be risky. After the repair, the ice maker started working again so thats all I'm going to worry about right now. I understand that GE has come up with a fix, a little heater they install behind the dispenser. GE will be hearing from me, my frig is only a little over 3 hears old. GE also doesn't support their product very well. Good luck, I know I didn't help much but maybe it will help to know you are not alone.
