You are taking too big a bite out of your humidity at one time ... plade the adjustment on a higher setting for now. When youe machine has achieved that goad, ower the setting a bit.

Alternatively, set a small fan to blow more room air on the coils ... you will probably still have to adjust the stting higher ...

IIt may very well be that the the air intake filter needs to be removed and cleaned. But, before doing this, turn the unit OFF & unplug it. Allow the unit to completely thaw, before removing the filter.Never operate the unit without the filter in place, As this could damage the unit.

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.

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.

Why is my dehumidifier icing up.


The room temperature is probably too cold, or there's poor airflow
Here's some info that should help you figure out what's causing the problem:

If the evaporator coil is frosting completely and evenly, the most common cause is that the room temperature is too cold. Most dehumidifiers are not meant to be used when the room temperature drops much below 70°F and certainly not below 65°F (depending on humidity). There are however some models called "basement" dehumidifiers which are.

Another possible cause on standard models is poor air flow through the unit. If the fan motor is not turning fast enough (or at all) or the evaporator, condenser or filter (if used) being plugged can also cause this symptom .

My dehumidifier model BHD-501-D is icing up. The fan and compressor are running, do I need a new thermostat?


You may, but more than likely, the air intake filer needs to be cleaned and the compressor coils wiped down and cleaned. After cleaning the coils, a light coat of WD40 helps to preserve them.

Before attempting any cleaning or service work, turn the unit OFF and unplug it from the wall outlet and allow it to thoroughly thaw. Keep in mind, a dehumidifier will freeze up, if the room temperature is below 40 degrees. Also, where you have it installed may be a problem. Particuarly, a basement. Where the air temperature is colder at floor level.

In case you have misplaced your Owners Manual, I have included a link to it that you can download & print for future reference. Be advised, your Model Number is not for a Sunbeam Dehumidifier, it's for a Comfort Aire dehumidifier that's manufactured by Heat Controller Inc.

My lg dehumidifier is collecting ice on top and no water is collecting in waste. Is it dead? this is a new problem but machine is not old


Sounds as if the air filter may be clogged, which causes the coils to freeze. Unplug the unit and allow it to thaw. Once thawed, follow the Owners Manual"s instructions on accessing, removal and cleaning of the air filter. That should solve your problem.

The dehumidifier isn't taking the moisture out of the air.


is the compressor in the unit hot to the touch,or are the coils freezing and thawing when it runs<if so you probably need to add some R-134a refrigerant,these type of units are notorious for losing all or part of their refrigerant charge,but unless you have the equipment to remove old refrigerant and vacuum the system down and recharge it it can get costly

Year 2005 cycling fan and compressor


Your unit is probably operating in defrost mode. When you use a dehumidifier in a cold room, the condensing coils can freeze water. The unit senses this and thus stops the compressor until the water frozen on the coils melts. Then it resumes its cycle. This is a problem you will have during the winter months. It makes the operation of the unit inefficient, but this is otherwise normal behavior.

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.
