6  Trouble 

shooting 

 

Before

 

calling

 

for

 

service,

 

please

 

read

 

the

 

following

 

troubleshooting

 

table

 

first.

 

This

 

can

 

save

 

both

 

your

 

time

 

and

 

money.

 

The

 

table

 

contains

 

common

 

problems

 

except

 

those

 

caused

 

by

 

defects

 

in

 

workmanship

 

or

 

material

 

of

 

the

 

refrigerator.

 

 

Problem

 

Cause

 

Solution

 

Refrigerator

 

Operation

 

 
 

 

The

 

compressor

 

does

 

not

 

work

 

 

 

 

The

 

refrigerator

 

is

 

in

 

the

 

defrosting

 

cycle.

 

 

The

 

refrigerator

 

is

 

not

 

plugged

 

into

 

a

 

power

 

outlet.

 

 

 

This

 

is

 

normal

 

for

 

an

 

automatic

 

defrosting

 

refrigerator.

 

 

Verify

 

the

 

plug

 

is

 

plugged

 

in

 

the

 

socket

 

firmly.

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

The

 

refrigerator

 

runs

 

frequently

 

or

 

runs

 

for

 

too

 

long

 

period

 

 

 
 
 
 
 
 
 

 

The

 

indoor

 

or

 

outdoor

 

temperature

 

is

 

high.

 

 

The

 

refrigerator

 

has

 

been

 

powered

 

off

 

for

 

a

 

period

 

of

 

time.

 

 

The

 

door

 

is

 

opened

 

too

 

frequently

 

or

 

for

 

long

 

period.

 

 

The

 

door

 

of

 

the

 

fridge/freezer

 

storage

 

compartment

 

is

 

not

 

tightly

 

closed.

 

 

The

 

temperature

 

setting

 

is

 

too

 

low.

 

 

The

 

door

 

gasket

 

of

 

the

 

fridge/freezer

 

storage

 

compartment

 

is

 

dirty,

 

worn,

 

cracked

 

or

 

mismatched.

 

 

In this

 

case,

 

it

 

is

 

normal

 

for

 

the

 

refrigerator

 

to

 

run

 

longer.

 

 

Normally,

 

it

 

takes

 

8

 

to

 

12

 

hours

 

for

 

the

 

refrigerator

 

to

 

totally

 

cool

 

down.

 

 

Warm

 

air

 

enters

 

the

 

refrigerator

 

and

 

causes

 

it

 

to

 

start

 

frequently.

 

Please

 

do

 

not

 

open

 

the

 

door

 

too

 

frequently.

 

 

Ensure

 

the

 

refrigerator

 

is

 

located

 

on

 

a

 

level

 

ground

 

and

 

there

 

is

 

no

 

food

 

or

 

container

 

jarring

 

the

 

door.

 

See

 

“door/drawer

 

opening/closing”

 

in

 

section

 

“Problem”

 

 

Set

 

the

 

temperature

 

higher

 

until

 

a

 

satisfactory

 

refrigerator

 

temperature

 

is

 

obtained.

 

It

 

takes

 

24

 

hours

 

for

 

the

 

refrigerator

 

temperature

 

to

 

become

 

stable.

 

 

Clean

 

or

 

replace

 

the

 

door

 

gasket.

 

A

 

leakage

 

gap

 

of

 

door

 

gasket

 

can

 

cause

 

a

 

longer

 

running

 

time

 

of

 

the

 

refrigerator

 

in

 

order

 

to

 

maintain

 

desired

 

temperature.
