What we can confirm
Code 30-9-10, from the manufacturer's own pages
A code is only meaningful together with the generation showing it — the same two digits mean different things across generations, and that is the commonest reason a code looked up online leads somewhere wrong. This one is recorded on Classic.

What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
No ice, slow ice, cloudy ice Ice maker not working
Production that stopped, or halved over a season. Water supply, the freeze cycle and the condenser are the three places this ends up, and they are easy to tell apart.
- Stopped after a filter change
- Half the ice it used to make
- Cloudy cubes instead of clear
On the same generation
What else belongs to the Classic
A code belongs to a generation rather than to one cabinet. These are the other codes yours can show, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Sub-Zero error code 30-9-10
What 30-9-10 tells you
Codes in the 30s cover the ice, water and dispenser side: valves, the check valve, the dispenser door. The unit usually keeps cooling normally, which is why these are noticed as "no ice" rather than as a temperature problem.
The same digits mean different things across generations, so 30-9-10 on one series and 30-9-10 on another are not the same conversation — the number on the data plate is what separates them, and the model pages say what each generation means for a repair.
The manufacturer publishes this code without saying what it stands for, and we do not guess at a meaning we cannot verify — what it narrows down is above, and what it means exactly is settled at the appliance. The code index covers how the codes are structured, what to photograph before you call, and the questions we are asked about them.
