appliance, personal injury and property damage can result. The manufacturer or seller maintains no liability
for the interpretation of this information, nor can it assume any liability in conjunction with its use. When
servicing this product, under no circumstances should the original design be modified or altered without
permission from LG Electronics. Unauthorized modifications will not only void the warranty, but may lead
to property damage or user injury. If wires, screws, clips, straps, nuts, or washers used to complete a

To avoid personal injury, disconnect the power before servicing this product. If electrical power is required
for diagnosis or test purposes, disconnect the power immediately after performing the necessary checks.
Also be aware that many household appliances present a weight hazard. At least two people should be
involved in the installation or servicing of such devices. Failure to consider the weight of an appliance could
result in physical injury.
ESD NOTICE
Some of the electronic components in appliances are electrostatic discharge (ESD) sensitive. ESD can
weaken or damage the electronics in these appliances in a manner that renders them inoperative or
reduces the time until their next failure. Connect an ESD wrist strap to a ground connection point or
unpainted metal in the appliance. Alternatively, you can touch your finger repeatedly to a ground
connection point or unpainted metal in the appliance. Before removing a replacement part from its package,
touch the anti-static bag to a ground connection point or unpainted metal in the appliance. Handle the
electronic control assembly by its edges only. When repackaging a failed electronic control assembly in an
anti-static bag, observe these same precautions.
