Solutions
Turn the control ON. Refer to the Setting the
Controls section for proper temperature
settings.
Demo Mode allows the lights and control
display to work normally while disabling
cooling to save energy while on the
showroom floor. Refer to the Setting the
Controls section for instructions on how to
disable Demo Mode.
During the defrost cycle, the temperature
of each compartment may raise slightly.
Wait 30 minutes and confirm the proper
temperature has been restored once the
defrost cycle has completed.
It may take up to 24 hours for each
compartment to reach the desired
temperature.
If the refrigerator was stored for a long period
of time or moved on its side, it is necessary
for the refrigerator to stand upright for 24
hours before connecting it to power.
Modern refrigerators require more operating
time but use less energy due to more efficient
technology.
The refrigerator will take up to 24 hours to
cool completely.
Adding food and opening the door warms
the refrigerator, requiring the compressor to
run longer in order to cool the refrigerator
back down. In order to conserve energy,
try to get everything you need out of the
refrigerator at once, keep food organized so
it is easy to find, and close the door as soon
as the food is removed. (Refer to the Food
Storage Guide.)
Firmly push the doors shut. If they will not
shut all the way, see the Doors will not close
completely or pop open section in Parts &
Features Troubleshooting.
