Solutions
Firmly plug the cord into a live outlet
with proper voltage (refer to Electrical &
Grounding Requirements).
Before proceeding to replace LED, unplug the
refrigerator or turn off power at the circuit
breaker or fuse box.
NOTE: The refrigerator and freezer
compartment lamps are LED interior lighting,
and service should only be performed by a
qualified technician.
Floor is weak or uneven or leveling legs need
adjusting. See the Installation section for
leveling instructions.
Modern refrigerators require more operating
time but use less energy due to more efficient
technology.
The compressor will run longer under warm
conditions. At normal room temperatures
(70°F) expect your compressor to run about
40% to 80% of the time. Under warmer
conditions, expect it to run even more often.
The refrigerator should not be operated in
surrounding temperatures above 110°F.
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.)
The refrigerator will take up to 24 hours to
cool completely
See the Adjusting Control Settings section.
Firmly push the doors shut. If they will not
shut all the way, see "Doors will not close
completely" in the Troubleshooting section.
This prevents air transfer and makes the motor
work harder. Clean the back cover. Refer to
the Care and Cleaning section.
