This video is how to replace the dispenser lever on a Samsung ice maker. I had an issue where only water came out if I hit the water or the ice lever. This shows what was wrong and how I replaced it. Parts for this are difficult to find so I had to buy a different part and use the lever's from that part to fix mine.
I purchased a part from searspartsdirect.com

Total, with shipping and tax was around $100 but it beats paying for service or replacing the refrigerator.
