Product review (5 stars): Saved time and money!
Our icemaker quit working, the inside of our freezer there was a red light flashing.  After looking on the internet I found that it was probably the sensor.  Instead of calling the repairman and paying for a house call we figured for under 40.00 it was worth a shot for the Whirlpool Gold refrigerator we have.

I changed both sides even though I figured only one side was bad, PRESTO, it starting producing ice again.  I highly recommend this product, for the price you can't go wrong.  I would imagine this is a pretty universal product as well for many models.
