Dehumidifiers will work only down to the temperature
for which they are designed. If there is no operating temperature
stated, then it is a 65 degree model, and it will freeze up below
65 degrees. In some models this will cause the compressor to shut
off, allow the ice to melt (could be an hour or so), restart, refreeze,
and the cycle continues with no water being removed and the electrical
costs mounting. And, unfortunately, in some units, the compressor
does not shut off and stays on and the frost on the coils becomes
ice that becomes a block of ice that blocks the airflow and eventually
burns out the motor. This is why we recommend a low
temp dehumidifier for areas of the country where the temperature
can fluctuate down to 40 degrees at night.

DEHUMIDIFIER PROBLEMS
There is little or no water in the bucket
If your dehumidifier doesn't seem to run frequently
and the humidity in the room remains high, adjust the humidistat
control to a drier setting. If the dehumidifier seems to run constantly,
but there's little or no water in the container, there is possibly
a problem with the refrigeration system. Try cleaning the air filter
and the unit itself, but if that doesn't work, you will need a qualified
appliance repair person or facility.
The indicator light is on, but the unit won't
run
The water tank may be completely filled. Most dehumidifiers
have a safety switch to turn the dehumidifier off when the water
tank is full. It is usually a float inside the tank to trigger this
switch and prevent the tank from overflowing. If the tank is empty
and the unit doesn't run, look at the inside wall against which
the tank pushes to see if there's a switch or mechanism present.
Sometimes just pushing in the bucket a little differently will press
the switch. Also, you may be able to activate or bend the switch
slightly with your finger to solve the problem.
The dehumidifier runs, but no air is coming
out of the machine
Your dehumidifier has a fan that draws the room air
over the coils. If there is no air movement from the unit, it is
possible that the fan motor may have burned out. If so, the fan
motor needs to be replaced.
There is frost on the coils
The coils you see on the back of your dehumidifier
are called the evaporator. When the unit is running, these coils
turn ice cold. As the fan draws the moist air over the coils, the
humidity in the air condenses on these coils. And if the temperature
of the air blowing over the coils is too cool, this condensation
will freeze on the coils.
Possible solutions might be:
- Add heat to the room in which the dehumidifier is located.
- Turn the unit off to allow the temperature in the room to rise.
- Place the dehumidifier on a shelf or table (the air is coolest
near the ground).
The container seems to fill up too quickly
When the container seems to fill too often, it means
your dehumidifier is working properly. However, if the container
fills quickly day after day, there may be additional moisture in
the air due to a pipe or water leak or an open crawl space. If so,
it would be best to correct this problem by stopping the leak or
closing off the crawl space.
