Disconnect the power to the icemaker. Does the clicking stop. If it does it is the servo motor. Sub Zero are highly overengineered, you will need a technician. These days they fix with a laptop.

Well, you probably have a bad defrost terminator if the fan is running. If the fan never runs, it's probably a bad fan. the terminator is what tells the heater when the defrost is done so it doesn't overheat. If it goes bad, the self defrost quits working. Another option is the defrost tier may be bad.
If you remove the grille up top the tier is mounted in a panel next to the condenser. it has a little place where you can turn it clockwise with a flathead screwdriver to "fast-forward" it. With the freezer still turned on, turn that timer very slowly clockwise. it will make tiny little clicking noises. turn it until it makes a much louder click. It should now be in defrost mode. If you go too far, just turn it all the way around again. Now wait a few minutes and see if it starts defrosting the ice in the freezer on the coils. if the defrost system starts working , you need a timer. The old part # was 3081180, but the deal should know what you need and be able to cross it. If it does not defrost, it is probably that terminator in the freezer, mounted to the coils just to the right and behind the icemaker. That is much harder to get to . Good luck!

This is either the defrost sensor or the main board. Neither of which you can do anything about with no parts. https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Refrigerator/55-114-539299-/Sub-Zero-Refrigerator-not-defrosting-642

The sub zero should make ice soon after being installed. If there is ice around the door frame of the freezer there may be a problem with the door frame heaters. There should not be ice around the door frame.

Hello, your refridgerator in most likely in defrost cycle. the noise your hearing is the water dripping on the hot heater and ice dropping off the evaporator. should only last 15 minutes and then your all set. Mike

Sounds like the gear is failing in the ice maker unit. I would replace it.

We have the same SubZero unit and the water leak is the ice maker line or the pan that catches condensation. If you unscrew the panel at the bottom, you will be able to take the pan out and see if the water is from there. If it is from the ice maker line (which was plastic on ours), you should fix this right away as we didn't and we ended up having a $10,000 flood that ruined our hardwood floors. Also, the increased motor noise happened to us as well, but when we had the motor replaced, it is not much quieter.

If you have a warranty with Sub-Zero 650, I would call them to come and take a look at it; it may be better to have them fix it.

When my repair tech came out, he showed me that the fill tube sometimes retracts toward the rear of the freezer. He simply pulled it forward with a pair of needle nose pliers until it rested in the delivery reservoir. This placement allows the detector to know when the tray is full and shut off; thus not overfilling the freezing tray and/or splashing additional water onto the freezer wall and into the ice cube drawer.
