Troubleshooting Guide - LG LTC20380ST Owner's Manual

UNDERSTANDING SOUNDS YOU MAY HEAR
Your new refrigerator may make sounds that your old one
did not make. 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
describes the kinds of sounds you may hear and what
may be causing them..
Clicking:
The defrost control 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:
Rattling noises may come from the flow of refrigerant, the
water line, or items stored on top of the refrigerator.
Whooshing:
• Evaporator fan motor circulating the air through the
refrigerator and freezer compartments.
• Air being forced over the condenser by the condenser
fan.
• Ice compartment fan in the freezer on the left side of
the refrigerator when the doors are open.
Gurgling:
As each cycle ends, you may hear a gurgling sound
caused by the refrigerant flowing through the cooling
system.

TROUBLESHOOTING GUIDE

Popping:
Contraction and expansion of the inside walls.
Sizzling:
Water dripping on the defrost heater during a defrost
cycle.
Vibrating Noise:
If the side or back of the refrigerator is touching a
cabinet or wall, some of the normal vibrations may make
an audible sound. To eliminate the noise, make sure that
the sides and back cannot vibrate against any wall or
cabinet.
Dripping:
Water running into the drain pan during the defrost cycle.
Pulsating or High-Pitched Sound:
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,
but is still more energy efficient than previous models.
While the refrigerator is running, it is normal to hear
a pulsating or high-pitched sound.

Solutions
Firmly plug the cord into a live outlet with
proper voltage (see Electrical & Grounding
Requirements).
Replace the fuse or reset the circuit
breaker. If the problem persists, contact
an electrician.
Refer to the Setting the Controls section.
Wait about 30 minutes for defrost cycle
to end.
The refrigerator is in DEMO mode. The
Demo Mode disables the cooling system
and only the lamps and display will work
normally.
To disable Demo Mode, press the
TEMPERATURE ADJUST button until you
set the desire temperature level. When
demo mode is deactivated, the OFF light will
turn off.
