PROBLEM:
POSSIBLE
CAUSE
/
SOULTIONS:
Moisture
collects
inside
Door
gasket
is
not
sealing
properly.
Check
for
debris,
cracks,
and
items
passing
through
door
at
the
gasket.
The
refrigerator
or
freezer
is
facing
a
doorway
or
is
underneath
of
air
conditioning
vent.
Relocate
the
unit
or
redirect
air
vent.
Too
many
door
openings.
Minimize
time
door
is
open.
Hot,
humid
weather
increases
condensation.
Make
sure
there
is
a
water
trap
(U
‐
shaped
loop)
in
the
drain
tube
near
the
compressor.
This
will
“trap”
a
small
amount
of
water
in
the
loop
and
prevent
air
from
entering
the
chamber
through
the
tube.

MOISTURE
DURING
THE
SUMMER
SEASON
The
amount
of
moisture,
condensation,
or
high
humidity
related
issues
increase
during
the
summer
and,
in
most
cases,
will
self
‐
resolve
when
the
weather
cools
down.
Please
note
a
refrigeration
system
does
NOT
generate
moisture
or
water
but
simply
condenses
the
moisture
that
is
already
in
the
chamber.
Keeping
the
unit
in
an
air
conditioned,
low
humidity
space
will
resolve
many
issues.
Other
things
you
should
check
1.
Location
of
the
refrigerator
(See
Quick
Troubleshooting
Guide
above)
2.
Door
sealing
and
frequency
of
door
opening
event
(See
Quick
Troubleshooting
Guide
above)
3.
Make
sure
there
is
a
water
trap
(U
‐
shaped
loop)
in
the
drain
tube
near
the
end.
This
will
“trap”
a
small
amount
of
water
in
the
loop
and
prevent
air
from
entering
the
chamber
through
the
tube.
