The Cooling Off mode (also called Shop mode) is designed for use by
retailers when they are displaying refrigerators on a retail floor.
In the Cooling Off mode, the refrigerator's fan motor and lights
operate normally, but the compressors do not run so neither the
fridge nor the freezer becomes cold.
To enter or exit the Cooling Off mode, press and hold Temp., Power
Freeze, and Lock simultaneously for 5 seconds. When the Cooling Off
mode is on, the refrigerator chime sounds, and the refrigerator shows
"oF" on the display.
