Product review (1 stars): Choose carefully.
Be very careful.  While this is very similar to the board in my refrigerator (and swaps in easily), it is apparently for a different version of my model.  (There are several components on my board that are not present on this one.)  I had to put the original board back just to get back to my normal level of malfunction.  My RF4287HARS was made in 2011, and this does not work in it.
