most units draw in the front and expel from the rear air , keeping filters clean (never run without one) is important for this function , frost on coils is a sure sign that air flow is low , or might be unit has lost [part of its gas charge due to heat build up from loss of cooling
MIKE - I have the same problem...previously, there was NEVER any frost, and the unit worked just fine. Now, all of a sudden in the last week, frost has been forming...water no longer traverses thru the tube into the sink...and the unit is basically useless/
I think when the original person said "frost", they meant ICE!
Hi,
The unit has leaking freon and is low on charge... not worth fixing...
Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.
Hi, Dehumidifiers freezing up can be causes by a few different problems. Here is a tip that I wrote to help people with the freezing dehumidifier problem....
if the room air is cooler than the dehumidifier then they will frost over. normally frosting over means loss of freon but because it is a closed system there probably isn't. if the air's moisture level [humidity] is low then don't even run the machine.
Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem
expected? of course!
this is not ur solution
try draining all the water to the sewerage
if u cant try to pump it out with a vacuum cleaner (that can pump water) or a pump
then turn on the Dehumidifier
every time it frosts turn it off untill it defrosts
or u can heat up the basement with a bellower and the Dehumidifier
wont frost
A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely.
1) Be sure the unit is set far enough from the wall so that airflow isn't restricted.
2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
