Product review (5 stars): Installed easily. Had to unplug the wiring connection from the ...
I used this model (626661) to replace model #626681 which came with the refrige (Whirlpool).  Installed easily.  Had to unplug the wiring connection from the original ice maker to use for the new connection, but that was not a problem.  Check Youtube for videos to determine if it's the ice maker that isn't working, or if some other part isn't working.
