TOPIC POSSIBLE CAUSE SOLUTION
OPERATION
Dehumidifier will not turn on
Electrical power cord may not be
plugged in, or connection may be
loose.
Make sure plug from power cord fits tightly into wall
outlet.
Make sure there is power to outlet.
Fuse could be blown or
circuit breaker tripped.
Replace fuse or reset circuit breaker. Do NOT increase
fuse capacity. Call qualified electrician to correct circuit
overload problem. Call local utility company to correct
power outage.
Dehumidifier will not run
(humidity is still present)
Overflow tank could be full (indicated
by full light being lit).
Drain bucket and replace correctly.
Humidistat setting may be too low.
Increase humidistat setting by turning clockwise. This
will increase the amount of humidity pulled from the air.
Frost may be present on coil.
Allow dehumidifier to cycle through the frost thawing
process. Normal operation will continue once frost has
been thawed and removed from coils. Do NOT remove
manually as damage may occur on the coils.
Dehumidifier is running, low
collection of water
Humidistat setting may be too low.
If humidity is present, increase humidistat setting by
turning clockwise. This will increase the amount of
humidity pulled from the air.
Unit is effectively removing humidity.
If dampness and odors have been eliminated,
dehumidifier is operating normally.
FROST BUILDUP
Light buildup of frost is present
First time dehumidifier has been
used.
Normal.
Air temperature could be too cold
(less than 65 °F).
Increase room temperature, if possible. Move away
from cold surfaces, such as outer walls or drafts.
Heavy buildup of frost is present
Humidistat setting may be too high.
Lower the humidistat setting by turning counter-
clockwise. Use lowest setting that controls dampness
and odors.
Frost thaw cycle may not be working.
If humidistat setting is already at low, this could be the
problem. Unit needs to be serviced.
Coils could be dirty. See Care and Cleaning.
HUMIDITY REMOVAL
Little collection in drain pan
(Humidity still present)
Air flow could be restricted through coils. Move dehumidifier to a better ventilated location.
Air filter could be dirty.
Vacuum filter with a brush attachment. Order new filter
for replacement if necessary.
Coils could be dirty. See Care and Cleaning.
Humidistat setting may be too low.
Increase humidistat setting by turning clockwise. This
will increase the amount of humidity pulled from the air.
Frost may be present on coil.
See Frost Build Up, above.
Little collection in drain pan
(Humidity not present)
Humidity is already within comfort zone
range.
Normal. Judge effectiveness by removal of dampness
and odors.
