About a year of owning this fridge the ice make started making a knocking sound instead of ice. After a lot of frustration I gave up on it and just turned it off. I can live without ice and everything else was great I love the self filling pitcher. 
Now another year later the ice make started making the same knocking sound again. The ice make is off! After another round of troubleshooting I removed the ice make altogether but I am so frustrated. Samsung has been nothing but a disappointment when it comes to appliances.
