What we can confirm
Code 35-3-35, 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.

The most common call Refrigerator not cooling
A cabinet that runs warm, cools unevenly, or holds temperature overnight and not by day. Five ordinary causes, hundreds of dollars apart — and how to tell which one you are looking at.
- Warm on one side, fine on the other
- Holds overnight, drifts by day
- Compressor running far longer than it used to
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 35-3-35
What 35-3-35 tells you
On the series that display it, 35-3-35 is logged against the condenser — fan. That narrows the diagnosis to one subsystem, which is genuinely useful — it does not, on its own, say which part in that subsystem has moved out of range.
Codes in this range are fan-related — condenser or evaporator fan speed out of range. In this climate that is most often a condenser packed with dust or corroded by salt air rather than a failed motor.
The same digits mean different things across generations, so 35-3-35 on one series and 35-3-35 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 code index covers how the codes are structured, what to photograph before you call, and the questions we are asked about them.
