Improve its heat-insulation property. If the door has deformed or the door
seal is not tightly sealed against the case body, repair them, respectively.
5) Too much food is placed in the refrigerator, or is placed too densely,
resulting in poor ventilation or poor conditions for temperature sensing, and
hence no stoppage of the compressor.
6) Too
high
ambient
temperature
Proper
ventilation
and
heat
Dissipation make the compressor running without stop
F. Electric Leakage of regrigerator
1) Slight electric leakage
Electric
insulation
has
deteriorated
due
to
being
affected with damp,
thus resulting in slight electric leakage.
2) Serious electric leakage
Refrigerator
case
has
become
live
due
to
faults
occurred
in some
electric devices
or
the
erroneous
wiring
in
installing
power
cord plug or
outlet by the user.
This is very dangerous.
3) Electric leakage test
a) Slight electric leakage
A tingle sense
will
be
experienced
as
soon
as
you touch
the metal parts
of the refrigerator
with
your
hand
.When
you
test
them
with a test
pencil ,its
neon
lamp
will
come
on
.In
that
case
,the
first
thing
you need to
do is to
determine
whether
the
grounding
is
perfect
.If
the
grounding is no
problem
,turn
off
the
refrigerator
immediately
,then
check
the
insulation of
electric circuits
with an
Voltmeter
b) Serious electric leakage
Never
touch
the
case
body
of
the
refrigerator
,its
door
handle
or other
metal parts
with
your
hand
.Test
the
refrigerator
with
a
test
pencil ,it will
light up
intensively
;measure
the
resistance
between
the
power
cord plug
and the
case
body
with
an
Volt meter
,the
reading
will
be
zero
(0%); in the
worst case
,the
fuse
will
be
blown
.Check
the
3-prong
outlet
to
see whether
the live
wire
and
the
Neutral wire
inversely
connected
,this
makes the
ground protection lead-out from the power cord plug
being
connected to the
live wire
.Another
possibility
is
that
the
live
wire
&
Neutral wire
of
the outdoor
power supply
circuit
have
been
inversely
connected
accordingly ,this
makes the Neutral wire become a live
wire .
G .Stronger vibration and loader
noise
1)
Refrigerator
placed improperly
a) Uneven ground
Uneven
ground
will
cause
the
refrigerator
to
be
placed unsteadily
causing stronger vibration and noise during its operation .
b) Leveling screws not properly adjusted
If the leveling screws on refrigerator legs have not been adjusted
properly ,vibration and noise will still occur even if the refrigerator has been
placed on a level ground .
2)
Abnormal noise from compressor
