Mine does the same thing! If you pull out the ice drawer, there is a small square opening behind the ice drawer about 1" by 1". If you stick your finger in this opening and move the slide lever up and down a few times, you can replace the drawer and it will work fine for a few days. Then, you may have to repeat this practice. I have not yet found a permanent fix, but will post it here when I do.
