Under extreme humidity conditions the evaporator coils can get frozen causing a blockage in the ventilation, and instead of dehumidifying, it will freeze up like a freezer that does not have defrost capability.

Try a more medium dehumidifying setting % so that it won't get quite so cold.

If the fan is working in the shroud, then this can help the unit work, but maybe it's working 'too' well as far as getting too cold.

Wish you luck on it.

We have two Danby Premiere Dehumidifiers. Both have stopped picking up water. The filters are clean, the fans run and there is alot of moisture in the air? Any ideas on how to fix them?


I assume that you have already:
  • Emptied the water buckets.
  • Are sure the buckets are properly in place.
  • Are sure the bucket switches are not stuck in the full bucket position.
  • Cleaned the cooling coils.
  • Verified that the controls are set for a low humidity
  • Verified that there are no trouble lights or codes,
  • Know that the area to be dehumidified is well above freezing..
It sounds like they are both stuck in defrost mode or the compressors overheated and need to cool off. "Both" is a bothersome word. Both might imply a power surge that wiped out the controls. I would:
  1. Unplug them and let them cool off 36 hours.
  2. Check your manual for a control panel reset.
  3. Take off whatever covers I could, to let me touch the cooling coils to be sure they get cool.
  4. Plug in # one and reset the panel.
  5. Let it run and see if the coils get cold.
  6. Plug in # two and reset the panel.
  7. Let it run and see if the coils get cold.
And then decided what to do next. Hopefully the cool off and reset did it .

Good luckl.

Why does blower wheel stop on Frigidaire dehumdifier?


Good Afternoon Desi,

I understand that the blower wheel is not spinning on your Frigidaire dehumidifier, model# FAD504DUD. I also see that the compressor will stay on unless the dehumidifier is unplugged. I suggest you contact the manufacturer for further assistance. They can possibly clarify why the compressor stays on and why the blower fan is not working. If not, they should at least be able to point you in the right direction of having your dehumidifier working. Hope this is helpful.

-Best Regards-
WP

Moisture collecting at the top front when running, even at mid power, over the control panel, sometimes turns to ice. if I shut it off when it is doing this the problem stops for awhile


Well, sounds like you have a good cold section in the dehumidifier-- that is good!-- But I agree-- we don't want water condensing on the surface-- and we surely don't need it turning to ice!
A couple questions to help us get to the next level of trouble shooting this problem:
1.) How cold is the room you are running the dehumidifier in?
(Obviously-- the warmer a room is, the easier to remove moisture--
the colder the room, the easier to drop the air temperature well below the freezing point-- making ice.)

2.) Have the air filters been cleaned/changed recently?
A dehumidifier needs a steady fast moving supply of air across its whole condenser/evaporator surface, in order to remove the maximum amount of water from the air, and not freeze up. (I would winder if something isn't blocking the flow of air toward the top of the coil?-- so that the coil in that area is going well below freezing temperatures, and thus allowing water (or ICE!) to develop near the top of the coil?-- Can you check air flow for us?

3.) You have suggested a good solution,-- especially if the above problems can not be easily corrected: Turn off the unit every few hours, and allow the warmth of the room, to defrost the coil....
In fact-- just to make sure that the air flow is not being restricted by ice deep within the coil-- let it stay off over night-- or bring the dehumidifier into a much warmer room, to make sure no ice is still blocking air flow deep within the coil..

Let us know what you learn about air flow, and get back with us-- THen maybe we need to take the trouble shooting deeper insicde the device.

I hope this helps-- MB

(New Unit) Motor Runs, Does Not Extract Moisture


Try setting you temperature or fan speed lower this may help.
In order for the unit to remove moisture the coil has to be below the dewpoint.

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.

Ice on dehumidifier


A dehumidifier works by cooling the metal pipes on the back of the unit to create condensation (water vapor in the air). This then drips into the collector bucket. If the unit runs too long the cooling tubes can get too cold and freeze the condesing water vapor. Unplug the dehumidifier and let the ice melt, when u turn it back on, turn it down, it may be up too high. If you find this solution helpful please rate it.

Thanks - Tech101
