My Samsung refrigerator was running great until we lost power from a bad rain storm. When power did return 4 hours later ice was being made by ice maker but would never pop out into ice bin ice would just stay in the maker and jam up. Well i had the idea to just hey why not buy a new ice maker 100.00 i can handle that simple plug and play well i was so excited with my new ice maker when it arrived i just had to hurry and install first two times ice was made i was like yay but then all the sudden the ice just started jamming again. I was like oh no. So i further researched and i had this is my last straw i will replace my main computer board located on the back of refrigerator. My refrigerator is a rf4287hars/xaa samsung made in april 2012. Well the pcb that i had in my current refrigerator was different than the one that appliance pros recommended so i talked to there tech and after further research he said just go with the current one you have so i did and hey now my ice maker is running perfectly after newly replaced board. I did replace water filter also but that still didn't fix ice maker problem what did fix my problem with the ice being made was replacing my main board.
