Hello, we are having some trouble with our Frigidaire dehumidifier model FDR30S1. It runs but is not pulling in any moisture. We've tried a few solutions but have not been successful thus far. What is...


Generally, most humidifiers work best between 60 -80 degrees . There is a model that is called a Low Temp model, that's designed for low temperatures in basements.

As far as your problem is concerned, there are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a manually
controlled unit, set the Manual Control Knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.


I hope this helps you troubleshoot and solve the problem. Thanks for choosing FixYa.

MY unit keeps on freezing up no problem with the filter dirty it gave me a problem after 3 months of use . i set it for 60% 50% it freezes up all the time i shut it off let it defrost and same thing all...


I think a part of the problem is that you have the humidity extraction level set to high. 50 to 60% is pretty much the humidity level throughout most of the year. Lowering it to 35%m should make a difference.

If you are using this in a basement application, the temperature at floor level can be 10 degrees cooler than at shoulder level. Most dehumidifiers don't work well at temperatures between 40 & 60 degrees F. Unless, they are Low Temp models designed for basement applications. Raising the unit up off the floor onto a sturdy table, counter top, etc. That can handle the weight of the unit, plus a full tank of water can resolve this problem.

If you can access the cooling coils, they may be dirty and need wiping off with a damp rag. Then flow with a dry clean rag to dry them. A light coating of WD40 helps to preserve the coils.

I hope this helps you to further troubleshoot and solve the problem. Thanks for choosing FixYa.

Coils freeze up. completely blocked. have to shut off to thaw coils. located in basement.


After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

Unit is in the basement. After 5 years the coils started to freeze up all the time and the compressor still runs


Dirty filter or coils would cause this problem, low charge would as well but clean the coils first. Or stat. setting could be set to low below 72 degrees can cause it to ice up.

I have a Fedders dehumidifer model # A70145D2A-A-R. It is a few years old and it's worked pretty great but now it just runs continuously and no moisture is gathered. What can I do to fix it? I was...


You'd be hard pressed to find a Fedders like yours. They've been out of business for several years.

There are several basic things that can cause what you described.

1. The humidity extraction level is improperly set. Lower the level to 32-35%

2. A dirty of clogged air intake filter. Turn the unit OFF unplug it and remove the filter for cleaning.

3. Obstructed air space. A dehumidifier requires a minimum of 12" clear air space around the entire
unit.

4. The ambient air temperature at floor level is between 40 & 60 Degrees F. Dehumidifiers do not work well in that temperature (Except low temp models). This especially true in a basement application, because the air temperature at floor level is colder than say, chest level. Raising the unit up off the floor onto a sturdy table, cabinet top, etc, that can handle the weight of the unit, plus a full tank of water, will normally resolve that problem.

5. The cooling coils are dirty and need to be cleaned.

Critical problems:
1 The humidity sensor has failed an needs to be replaced.

2.The compressor is low on refrigerant gas and needs to be recharged.

Sometimes the repairs (Time spent finding, the Parts & labor), if necessary, can cost almost as much or as much as a new unit, which would have a full warranty.

Hope this helped you troubleshoot the basic and solvable problems and you won't need to make any critical repairs. Please let me know. Thanks.

DEHUMIDIFER COILS FREEZE OVER, WHETHER MACHINE IS RUNNIG ON LOW OR HIGH. FILTERS ARE ALL CLEAN.


Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.

Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.

If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Coils freezing up


The largest culprits for freeze up are dirty filter, dirty coil behind filter....and on certain occasions, low on freon.

Doesnt take any water out


Most dehumidiers have a "Frost Guard" thermal protector on the condensor coil. This protector will turn the compressor off should the temperature fall below 65 degrees in the basement. The condensor fan will still continue to run anticipating the restart of the compressor.
Hence, 3 things could be wrong.
1. air temp.of basement is too cold
2. Frost guard could be faulty
3. Freon leak in condensor coil.
Assuring that basement temp. is above 65 degrees is about all you can do unless you have it checked out by a technician.

Iced up coils and will not dehumidify


I did a little digging around on the internet and found out that if the basement (or where ever you have your unit) is in an area where the room temp might dip below 65 degrees the coils may start to become "too efficient" in pulling the moisture/humidity out of the air and it begins to freeze on the coils before it can drip off into the reservoir. The site said to turn off the unit and let it thaw out, then restart it and see if everything works ok after that. If the temperature gets too low you might need to warm up the air in the room/basement before it will operate correctly again/not continue to freeze up. Hope this helps. Mine just did the same thing but we've had some pretty cold weather recently and the basement is fairly cold as well.
