Picture of ...Sub Zero model 632 Icemaker shutoff arm

SOURCE: Sub Zero 632 leaking water

Had the same problem on the same model (632). Turned out to be a plugged drain tube on the condensate collection trough located on back wall of the refrigerator. Simply pull out the crisper drawer (the drawer below the lowest shelf) and you'll bee the trough. The drip tube can easily be plugged by a vegetable leak or grape, etc which had fallen into this trough. Hope its as simple for you as for us.

The trick to putting the drawer back correctly is to ensure that the auger pushes into the motor coupling. To achieve this you will have to put the drawer in place and gently push it in while turning the auger inside the drawer by hand. You will know when it has clicked in.

The shut off arm is in up position. This is the off position for the ice make. Try pulling the down to the first level this will engage the micro switch to start the ice maker. Also, behind the ice maker is a 4 wire plug remove the plug and see if there were some electrical arcing. But first before removing the ice make plug--Please unplug the refrigerator first before work on the ice maker. stewbison
