Product review (5 stars): Went with this real Whirpool Ice Maker
I decided to spend a little more with this oem unit.  Works great and I am happy I did. One thing is if you  have an electric eye type switch, remove the circuit board and jump the connector to be sure you have full power to ice maker.  Mine had 34 volts, not 115.  Circuit Board had to be replaced.  Jumping at the unit did not detect this.  It is a bit harder to find this procedure on utube/internet, but it is there.
