Product review (5 stars): A bad valve CAN test good on an ohmmeter.
Although it did not mount to my Amana fridge exactly, it functions perfectly. The inlet is threaded for a supply line with a compression fitting; and the outlet is a simple push fit . I used the standard copper supply tubing that was already in place and the outlet tubing  was the plastic tubing that came on the fridge. I just sort of cobbled the assembly on to the back of the fridge with one sheet metal screw taking care not to put the plastic outlet tubing in harms way. We had ice very shortly thereafter. The coil on the bad valve tested good so initially I thought my valve was not the problem. But careful testing and diagnosing said it had to be the valve. It was. The magnetic pin that the coil pulls on with magnetism had come loose from the diaphragm and gasket that opens and closes the valve seat. So if you are quite sure your valve is bad but the coil tests good, understand that you can still have a bad valve!
