GE GSH25KGPAWW Ice Maker Overfilling - Does Not Shut Off Water

[mlochala]

The icemaker (WR30X10012) is overfilling itself and flowing water all into the freezer and ultimately it runs out into the floor. When it does this, it dumps a LOT of water into my kitchen floor.

My refrigerator is approximately 18 years old. A couple of months ago I replaced the water fill valve (plastic double solenoid device) as it had a hairline crack and was leaking water. For about two weeks, there were no problems. Then, one morning we discovered water all over the kitchen and into the living room. The water was still running out of the refrigerator. We turned the water supply off and I suspected the new solenoid water fill valve was the culprit. I assumed it was faulty, so I replaced it again. Within five or six hours of replacing it, the water overfilling happened again. I have had problems in the past with little pieces of ice jamming the ice maker, but never this.

My question is, does the ice maker itself determine when to shut off the water or does this command come from the control board on the back of the refrigerator. At this point, I'm inclined to believe the ice maker is at fault, but I was curious if the water filling function is a timed event from the control board or if there is some mechanism inside the ice maker that tells it to stop filling the water.

Have any of you had this issue before? How did you repair it? Ice maker, control board, or ????

The ice maker sends signal to the water valve to energize. The ice maker also is pre-set to keep the water valve energized for a specific amount of time. You most likely have a faulty ice maker. If the water pressure is within spec. Then the plunger will remain closed with no water seeping in. Solenoid activation would only take place with the presence of voltage drop from the ice maker.
