K.I.
Our main problem was that the motor on the icemaker blew and needed to be completely replaced. Of course, it was outside of the warranty period, and the repairman said that it's a very common problem. I hope for your sake that this isn't your problem, as it was almost $200 to fix. We've also had the piece of ice getting lodged in the tray like someone else mentioned which, obviously, is an easy fix. I agree that if you can find the manual, it's best to look there to help decipher the blinking lights.
Hope this is of some help.
