Product review (5 stars): Troubleshooting when you need to replace the water valve in your refrigerator, Manual Pic in review
Troubleshooting when you need to replace the water valve in your refrigerator
Water dispenser constantly dripping (never stops); it will overflow the tray on the dispenser.
You need to change the solenoid valve.

Ice maker, I will explain you my case. Suddenly the fan motor inside the freezer section started to make a loud noise that could be heard outside the refrigerator with both door closed.
Disconnect the refrigerator from the power outlet
I removed the back aluminum panel in the freezer to access the fan motor, I found a frozen lake and water fall coming from the top, the ice was starting to block the blades of the fan motor (there will be a point where the Ice will stop the blades from turning, at that point you will lose all the food that you have in the refrigerator section).
Turn the water valve off, that supplies water to the refrigerator, remove the ice, reinstall the back plate, and order the solenoid valve.  Do not re open the water valve that supplies water to the refrigerator, you will not have ice or cold water, but your freezer and refrigerator will continue to work.

Case One
Explanation on what is going on.
If the solenoid valve is not closing completely, a constant water drop will run towards the ice maker in an open channel /pipe, those drops of water will start to freeze making an ice dam behind the aluminum plate that cover the back of the freezer, the water will start to drop behind the aluminum plates, and on top of the freezer fan motor.

Case two
The water leak has a higher flow, it will overflow the ice maker, and into the ice bin, where you will have a solid block of ice and or the water may drop from the ice shut on the door

The procedure for changing the valve is fairly easy, if you are good with tools, there is no science to it.
Turn off the water valve that supplies water to the refrigerator, and unplug the refrigerator from the power outlet.
You only need a set of  inch socket drives, the screws are not too tight.
Remove the water inlet tube from the valve; remove the back cardboard from the back of the refrigerator.

The included instructions with the valve are clear and easy to follow, just make sure that you pay attention to the color of the valves / electrical plugs and the corresponding hoses.

I always recommend using the best tool that you have, your phone, taking pictures while you are working in case you have a doubt later.
To remove the hoses you only have to push in the valve white rings, while you pull the hose.

I hope the attached manual is readable large screen for you.

Hope you like the review if you have any question let me know.
