Sub-Zero Sabbath Mode: Lights, Alarms Off? What It Does

Updated October 2026 · By the Sub-Zero Repair Las Vegas service team

Quick answer

Sabbath mode on a Sub-Zero disables interior lights, alarms and some display functions for religious observance while cooling continues normally. If your lights don't come on and alarms are silent but food stays cold, the unit may be in Sabbath mode.
