1.
When
there
are
SHORT-type
troubles
with
EVA-SENSOR
of
F
and
R,
do
not
charge
the
defrost-heater
and
retum
to
the
normal
operation
after
pause.
So,
if
the
period
of
non-operation
of
the
defrost-heater
is
accumulated,
troubles
with
freezing
and
refrigerating
may
occur.
2.
When
there
is
OFF
of
Thermal-Fuse,
a
kind
of
safety
gadget,
snapping
of
wire,
or
troubles
with
RELAY
on
PCB,
troubles
with
freezing
and
refrigerating
may
occur
because
defrosting
is
caused
by
the
increase
of
natural
temperature
and
thus,
COMP
OFF
time
becomes
longer.
3.
When
there
are
OPEN-type
troubles
with
Defrost-Sensor
of
each
F
and
R,
HEATING
does
not
come
to
be
terminated
and
Thermal-Fuse,
a
kind
of
safety
gadget,
becomes
snapped
after
some
time.
So,
since
HEATING
operation
continues
to
operate
and
COMP
ON
does
not
operate,
troubles
with
freezing
and refrigerating may occur.
