Product review (1 stars): It might have been bad or good, I'll nvever know. Lesson learned.
I give it a one star since I really don't know if it would work or not. I got the part number from Whirlpool and apparently was the wrong part number. I did install it and found that it did control the water supply coming out of the refrigerator where one would get a glass of water, but it would not operate the ice maker. Since it was installed, the supplier threatened that he would not be able to take it back if it was used and admonished me that they sell new parts and not used parts. They told me that the decision to accept it would be up to a person who inspects these things. Faced with the prospect of them not accepting it plus a 20% restocking charge and the cost of freight I would be out an additional appros $12.00 besides the original cost of  $18.50 so I chose not to send it back. I threw it our and we opted to go back to ice cube trays and free up all that space in the freezer that the ice maker and ice cube bin takes up. Furthermore, Although I bought the unit thru Amazon, I will be careful not to buy anymore items from the distributor that supplied the part, plain nasty and non-cooperative.
