What L0 C
actually means.
The panel stops responding and shows L0 C. Someone pressed a key while the unit thought the door was closed. It can show up the first time a new unit is powered on. Sub-Zero's own checks are a stuck light switch and a door or drawer left open for a long time.

What to do when L0 C shows on the refrigeratorKind of codeMode, not a failure
A setting somebody chose, or an alert it raised on purpose — a showroom mode, a door or power alarm. Nothing has broken and no part is needed.
Usually leads toNo repair
Check that the light switch at the door opening is not stuck.

The compartment is warm but the appliance still has power and still makes noise.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for L0 C on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Check that the light switch at the door opening is not stuck.
Think back to whether a door or drawer was left open for a long time.
Keep the door closed for 45 minutes so the control board can reset.
If another code is showing with it, deal with that one on its own; Sub-Zero says the two are not connected.
Cleared?
Nothing needed repairing. If the refrigerator does not settle back to temperature, that is a separate problem.
What not to do
It cannot be brought up by pressing a sequence of keys, so it is not something you entered by mistake in a menu. If it will not clear after 45 minutes with the door closed, it needs a service visit.
