Took me a while to find this... so simple, I'm glad it isn't a big problem.
The Sabbath Mode is a feature that disables portions
of the refrigerator and its controls in accordance with
observance of the weekly Sabbath and religious holidays
within the Orthodox Jewish community.
Sabbath Mode is turned ON and OFF by pressing and
" on freezer temp and "
" on refrigerator
In the Sabbath Mode, the High Temp alarm is active
for health reasons. If a high temperature alarm is
activated during this time, for example due to a door
left ajar, the alarm will sound intermittently for about
10 minutes. The alarm will then silence on its own and
a red high temperature icon will display. The high temp
icon will continue to display, even if the door is closed,
until the Sabbath mode is exited and the icon reset. The
refrigerator will function normally once the door is closed,
without any violation of the Sabbath/Holidays.
