Sub-Zero reference · Denver, CO
Showroom mode lets a Sub-Zero light up, hold a panel full of figures and cool nothing at all. It is a setting rather than a failure, and Sub-Zero Pro Repair Denver rules it in or out first — (720) 704-2791.

Built-In 600-3 controls and the current Classic panel
Every other page in this section opens with a control trying to tell you something. This one opens with a control convinced it has nothing to report. The mode is named for where it belongs, and while it is set the panel keeps up appearances: two reasonable figures, no flashing word, no code filed away.
That is what makes it expensive to miss. A warm Sub-Zero with a calm display reads like a sealed-system question — and on Sub-Zero’s own run-time lists the sealed system is the last item to be checked, never the first.
Two set points on the panel above a cabinet sitting at room temperature
The symptom Sub-Zero publishes for this mode, near enough word for word. Those figures are targets on a screen rather than anything a sensor measured, and no compressor was asked to chase them.

Sr where a code would be, on a unit lately delivered, moved or bought off a floor
The setting travelling with the cabinet. It comes back out through the keys on the front: the unit is taken off at the power key, WARMER and COLDER are held together, and the power key is pressed once more.

Warm compartments, nothing stored in memory, and the SERVICE word not flashing
The combination that sends a visit toward the sealed system too early. Sub-Zero's tables put this mode among the first causes of that picture, ahead of anything calling for gauges.
No band covers this one — quoted after the diagnosis
The machine is safe; the food is not. Nothing inside is being strained, because nothing inside is working — idleness by instruction rather than by failure. Move what matters to another cold space, bring the unit out of the mode, and judge it on the temperatures it then holds.
