What we can confirm
Code 10-1-02, 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, Common to several series, Designer.

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.
-
The display asking for attention Service light or wrench flashing
A service light, a wrench symbol or a unit that beeps without any obvious change in temperature. What it means, why the code behind it matters, and what to do first.
- Light on, temperatures look normal
- Wrench symbol with no code shown
- Beeping that returns after a reset
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 10-1-02
What 10-1-02 tells you
Codes in the 10s are sensor and thermistor territory: a temperature reading that has gone open, shorted or implausible. The sensor itself is often the cheap end of the repair — but the same code appears when the wiring to it has been disturbed.
The same digits mean different things across generations, so 10-1-02 on one series and 10-1-02 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.
