Troubleshooting Guide - LG LSC27937SB Owner's Manual

UNDERSTANDING SOUNDS YOU MAY HEAR
Your new refrigerator may make sounds that your old
one did not make. Because the sounds are new to you,
you might be concerned about them. Most of the new
sounds are normal. Hard surfaces, like the floor, walls
and cabinets, can make the sounds seem louder than
they actually are. The following list describes the kinds of
sounds and what may be making them.

set correctly for the surrounding
conditions.
• The defrost timer will click when the automatic defrost
cycle begins and ends. The thermostat control (or
refrigerator control, depending on the model) will also
click when cycling on and off.
• Rattling noises may come from the flow of refrigerant,
the water line, or items stored on top of the refrigerator.
• Your refrigerator is designed to run more efficiently
to keep your food items at the desired temperature.
The high efficiency compressor may cause your new
refrigerator to run longer than your old one, and you
may hear a pulsating or high-pitched sound.
• You may hear the evaporator fan motor circulating the
air through the refrigerator and freezer compartments.
• As each cycle ends, you may hear a gurgling sound
due to the refrigerant flowing in your refrigerator.
• Contraction and expansion of the inside walls may
cause a popping noise.
• Water dripping on the defrost heater during a defrost
cycle may cause a sizzling sound.
• You may hear air being forced over the condenser by
the condenser fan.
• You may hear water running into the drain pan during
the defrost cycle.
• Firmly plug the cord into a live outlet with proper
voltage.
• Replace the fuse or reset the circuit breaker.
• Refer to the "Control Panel Features" section.
• Wait about 30 minutes for defrost cycle to end.
• Floor is weak or uneven or leveling legs need
adjusting. See "Door Alignment" Section.
• Firmly plug the cord into a live outlet with proper
voltage.
• See the "Light (LED) Replacement" section.
• Modern refrigerators with more storage space
require more operating time.
• The motor will run longer under warm conditions.
At normal room temperatures, expect your motor
to run about 40% to 80% of the time. Under
warmer conditions, expect it to run even more
often.
recently • The refrigerator will take up to 24 hours to cool
completely.
• Adding food and opening the door warms the
refrigerator. It is normal for the refrigerator to
run longer 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. See the
"Food Storage Guide" section.
• See the "Adjusting Control Settings" Section.
