Product review (5 stars): Samsung Refrigerator Main Circuit Board
I purchased a Samsung refrigerator that was five months past its warranty period and was told by repair technician that a new main control board was needed and it would cost $585.00.  You can imagine how happy I was to find the board for approximately $100 and I installed the board myself in 15 minutes.  The circuit board was shipped quickly and was exactly as indicated in the add.  Very happy with my purchase!
