How to clean coils on dehumidifier

How do I clean the coils? Remove panel and soap/water? It is freezing the coils when I run it on continuous setting and someone suggested cleaning the coils. I don't want to mess it up further so thought I would ask. I need it and can't afford a new one. Thank you!

SOURCE: Frigidare Dehumidifier will not turn off

Pressure and temperature is directly related with refrigerants in the system. Ice building on part of the coils shows that the pressure inside the system is low and the system has lost some of its charge. Very low humidity with a low ambient temperature will also cause such a problem.

Don, unless your dehumidifier is a Low temperature model, that very well may be the problem.
The air temp in a basement at floor level is colder than that chest level. Dehumidifiers don't work well at temperatures at 40 degrees F or less. Raising the unit up off the floor on to a sturdy table, counter top, etc, that is strong enough to handle it's weight, plus a full tank of water, will generally solve the problem. The higher up you can safely put it, the better. Also, lower the humidity extraction level to 35%. As 50% is just not low enough in a basement application.

Hope this helps you to solve the problem.

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.

Clean frigidaire dehumidifier cooling coil


Hello Friend, thank you for your post!

I see that you would like to know how to clean the coils on your Frigidaire dehumidifier and that it is no longer collecting water. The best way to clean the coils is by using a brush attachment from your vacuum. Typically there are one or two reasons why your dehumidifier is not collecting water. Either the setting might be set too high or not enough moisture in the room. I suggest changing the set point to a lower setting. As humidity drops in the room the amount of water will decrease and very little water may be generated even when in continuous mode. If these basic troubleshooting tips prove ineffective, then your dehumidifier may possibly have system issues. Is your dehumidifier still in warranty? If so, you might want to reach out directly to the manufacturer to determine the coverage on your dehumidifier and the procedures to any potential remedy in that regard. Best - Z

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

Coils freezing up..is this normal? Not sure how this is supposed to work. Could it be that it freezes the water, then turns off and empties into the pan?


The coils should not freeze up. If the fan is working, try lowering the setpoint to just below actual humidity. This will allow the dehumidifier to run and shut so water can drip off without freezing. If that works, slowly lower the setpoint over the next day or so. If the setpoint is too low, the unit runs continuously until it freezes, then never shuts down.

The coil is freezing up on my 2 year old Haier dehumidifier. The unit is clean and the temperature in the area it is used is 70 degrees. This unit is not suppose to freeze up. What is wrong?


If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. If your dehumidifier is freezing up then that probably means the unit itself is actually working well, and you probably just have the unit turned up too high for the conditions.

Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.

Also try using some warm soapy water to clean off any dust or oily residue from the cooling coils in the rear of the unit. Remember to also clean the air intake filter while you are at it.

The ambient temperature in the room may also be a bit too low, so you can try adding some heat to the room if necessary. A dehumidifier will not work properly if the ambient air temperature is too low. Basically, the warmer and more humid the room is, the better they work. Since warm air rises, you can even try lifting the unit higher up off the cold floor onto a bench or table where the air is warmer.

Sometimes the drain tube leading to the bucket is clogged. You can often clean this out by inserting the pointy end of a long heavy duty plastic zip tie and jiggling it around a bit. Do not insert anything metal or sharp into the tube or you may damage it.

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.

Doesn't collect water, freezes on top


clean filter and then check the coil behind the filter to see if clean. Biggest things that freeze a unit are dirty filter or coil...or low on freon.

If only the bottom part if your coil is geting cold or freezing, it's low on Freon.

ALL DEHUMIDIFIERS REQUIRE ROOM TEMPS TO BE AT LEAST 65 DEGREES AND A HUMIDITY OF AT LEAST 50 % TO OPERATE PROPERLY. ANYTHING LESS AND IT MAY FREEZE THE EVAPORATOR COILS. EVAPORATOR COILS WILL ALSO FREEZE IF THE COILS ARE DIRTY AND HAVE RESTRICTED AIR FLOW.TRY TAKING THE COVER OFF OF THE UNIT AND CLEANING BOTH SETS OF COILS INSIDE. THEY ARE COPPER OR ALUMINUM WITH FINS ON THEM.
ALSO CHECK THE FAN TO BE SURE IT IS RUNNING.
THAT WILL CAUSE AN OVERHEATING CONDITION AND WILL SHUT DOWN THE COMPRESSOR ALSO.
