Product review (5 stars): This works!
The end of September the plumber ran the line for the ice dispenser. Three weeks later, after returning from a week's vacation, I had ice but no water was dispensed. So, I checked out the internet for solutions. IceSurrender was recommended over trying the hair dryer method. Happily I found this available through Amazon and placed my order.

The instructions with the tool say to heat water in the microwave for 15 seconds; that barely warms the water that is pulled up into the plunger. I heated water in a coffee cup for less than 2 minutes. I inserted the tubing through the dispenser of my GE Pro as far as I could, with a cloth in the tray to catch drips. It took 4-5 attempts for this method to be successful; but it worked!

Much better than a hair dryer; not sure where to start with it. No repair person needed! The price is right for this handy tool! Now to decide where to store for the next time I need it.
