I bought a replacement ice maker from AppliancePartsPros.com and watched the YouTube video they made on how to install it. Easy - peasy - lemon - squeazy. The only problem encountered was the screw size for a plastic shield that sits on the back of the unit. The original Samsung screws were M18x11 metric round heads. The new part needed screws that were 48 x 3/32" SAE. These screws should be purchased at a hardware store BEFORE installing the new ice maker IF the original screws do not fit. My fridge is 12 years old so it is possible Samsung modified their threads. That being stated, the entire repair took about 10 minutes.
