What Service
actually means.
It means two different things depending on how it shows. Flashing between the zone temperatures, it says the compressor has been running far more than it should — a possible cooling problem. Lit steadily, it says an error code has been stored in memory.

What to do when Service shows on the refrigeratorKind of codeService indication
A light or a message asking for a visit. It says that something wants attention, not what, so the visit starts with a diagnosis.
Usually leads toDiagnostic visit
The visit that decides what the repair actually is, before any part is ordered.
Shows up asRefrigerator Running Constantly
The compressor never cycles off, and the cabinet may still be holding temperature.
MakeSub-Zero
Built-in and column refrigeration with dual sealed systems, serviced from the front and worth repairing far up the cost curve.

Sub-Zero shows this on 600 and 700 Series panels. The Classic series uses a wrench icon instead.
Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for Service on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Flashing and the temperatures are high: book a visit.
Flashing and the temperatures are near normal: switch the unit off, clean the condenser, check that the doors close, switch the breaker off for 30 seconds and back on. Book a visit if it returns.
Steady: there is nothing to do at home — book a visit.
What not to do
Do not treat flashing and steady as the same message. One is about how hard the unit is working; the other is a stored error.

Service indication on other makes
Built-in refrigerator
Flush with the cabinets, serviced from the front, and almost always repaired rather than replaced.
Refrigerator column
Separate refrigerator and freezer towers, each with its own sealed system — so a failure stays on one side.
Side-by-side refrigerator
Full-height freezer beside full-height fresh food, with the ice maker and dispenser built into the freezer door.
In Sub-Zero's own words
The word "Service" flashes between zone temperatures. 600 and 700 Series control panel shown.
Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Sub-Zero shows this on 600 and 700 Series panels. The Classic series uses a wrench icon instead.

Questions
about Service.
Can I clear Service myself?
Is a flashing Sub-Zero Service light as serious as a steady one?
Why did the Sub-Zero Service light come back after I cleaned the condenser and reset the breaker?
