Product review (1 stars): Failed after ten months
Perfect replacement for the optics boards that went bad in our Whirlpool side-by-side fridge.  The set I received is several revisions newer than the original set it replaced, so this could really be considered an upgrade as well as a replacement.

Swapping them out was a simple task.  A screwdriver is all one needs.

Now the icemaker is working again, and the wife and family are happy.

Edited on 3/31/2018:  Stopped working in less than ten months. Ended up having to order a different kit to get the ice maker working again.
