| The coils you see on the back of your dehumidifier
are the evaporator. When the unit runs, the coils get very cold. As
the fan draws the room air over the coils, the humidity in the air
condenses out of the air onto the cold coils. But, if the temperature
of the air the fan draws over the coils is too cool, the humidity
that condenses out of the air freezes on the coils. To remedy this problem, you can try any of these:
|
| Your dehumidifier has a circulating fan that
draws the room air over the coils. If there's no air movement out
the front or back of the unit, the fan motor may be burned out or
stuck, or the fan blade may be broken. If so, you need to replace
the fan motor or the fan blade. |
| The tank may be full. Your dehumidifier has
a safety device that turns off the dehumidifier when the water tank
is full. Usually the tank itself either presses against a switch or
there's a device connected to the tank that triggers a switch when
the tank is in place and full. If you've emptied the tank and the unit doesn't run, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger. |
| When the container fills quickly, your dehumidifier
is doing its job. If the container fills quickly for many days in
a row, you may want to locate the source of the humidity (for example,
is there an unsealed crawl space?) and see if you can correct the
problem at the source. |
| If your dehumidifier doesn't seem to run often
but the humidity in the room is high, try adjusting the humidistat
control on the dehumidifier to a dryer setting. If the dehumidifier
seems to run constantly, but there's little or no water in the container,
there may be a problem in the refrigeration system. Try cleaning the
unit. If that doesn't work, you can't repair the refrigeration system
yourself, you need a qualified appliance repair technician to do that. |

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.
