You can try cleaning the humidity sensor, which is on a circuit board
housed in a nylon clip attached to the cooling coils.
The sensor is in a plastic clip, which can be opened up and cleaned.
Some report success. Didn't work for me.

I ended up rewiring the unit so that a 5v control
line from the lower relay board goes through the SPDT bucket full switch,
turning on the control board when full (so it beeps), but otherwise
enabling the compressor and fan. The fan and compressor
are controlled by relays, which are driven by a ULN2003AN
relay driver. I fed the empty side of the full bucket switch back into
the relay driver to turn on the compress and the fan on high.
I plan to put a dehumidistat in series with this control line;
now it just runs till the bucket is full. A Broan DH100W dehumidistat
is 20 bucks. Could also put in a rotary switch to control the fan speed,
but for me high is enough.

I think this machine is made by Goldstar for Kenmore and Delonghi.
Stuff is just made to break and through away these days, which is a shame.

This dehumidifier is built in such a way that the fan runs all the time;however the compressor works only when it is needed. These infos are not specified in the booklet. It does not work like the old ones.

Be Safe or don't do it....

On the side with the lint screen, remove the five screws holding the top panel in place. The sensor that needs to be checked in mounted on the radiator fins. Remove the sensor and 4 pin connector. With a pin, remove the loose fitting housing the "sensor"...a circuit board that "shorts" with condensation...check corrosion and look for component damage on the oft chance the circuit board was damaged by some inappropriate poking or mechanical failure. Reassemble and replace sensor...

For a short life span...or out of warranty and only at your risk (IF have significant other or kids or pets or human DNA... don't do this...) .. guide wire through screen notch and attach to outer screen. Build fortress around exposed sensor and talk to insurance agent for a special rider...seriously be careful.



Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)

Taking all appropriate safety precautions.

...


Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the power button (green button in lower center) and plug in the appliance.

Watch the LCD screen as it conducts a self test...and wha...lah!.

Should have a working humidifier!

(your welcome).

no really..."de nada". :"don't touch your moustache" "Doye toche moche"(?), "prego".

No water collected


check to see if the fan is blowing across the condenser. there should be warm air blowing out the back. if there isn't, the fan may need to be replaced so the heat exchanger can cool down. may be running too hot. also check the condenser in the front to see if the air flow is blocked with dust. if so, change the filter if it has one. if there is cool air blowing, the compressor may not be turning on.

Older Haier model...hd074cw (?) Does not pull water from air into bucket. Just stopped working this summer. Compressor and fan both working. What else can I check??


If the compressor and the fan are working then the next thing is to make sure The entire unit is cleaned . This may require you to diassemble the unit . The refrigerant Coils must be clean in order for the compressor to shed heat and propperly function. Once the unit is cleaned out thoroughly, if you still have problems you could be low or Out of refrigerant. If so it usually does not make financial sense to replair these unless It is a very expensive(over$500) model. You would be better off to replace it.

Compressor and fan both kick on when starting. Frosts up (normal for this time of year) but then compressor stops but fan continues to run but compressor does not start up again....


From what you have described, it sounds like the defrost sensor may be bad. However, if you're operating the unit in a temperature of 40 degrees or lower. That's the problem. If in a basement application, keep in mind the floor temperature is lower than the air temperature.

Also, cleaning the air intake filter on a regular basis will help.

Hope this helped you. Please let me know.

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.

It runs but there is no water coming out. We have checked the hose for a blockage. What else could it be?


If the compressor is running but no air is blowing out, then your fan motor is shot. If the fan is blowing air but you don't hear the click and vibration when you turn it on, then your compressor needs replacing. Those are the most likely culprits.

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.

E3 is flashing on display panel


Calling two service centers, they both indicated that the main circuit board needed replacing. This would need shipping the unit!!, part and then labor. I figured over $120 - not reasonable. I then took the unit apart and followed the wires from the compressor to the back of the unit. This is where the moisture sensor was located - upper left. You'll see this when you take the filter off. Anyway, I cleaned the face of this part with a old toothbrush, used some compressed air to remove any dust. I then followed the wires with the black sleeve that went to what I think is a temperature sensor - also on the left. The wires go to a sensor that is pushed into a copper tube that is part of the cooling tubing. Gently pull this out, wipe it down and re-install. I then plugged the unit in, set the humidity level and it now works. I just put the unit back together and the compressor is turning on and collecting moisture! I will run it a few days and keep checking on it to make sure it doesn't go into the 'E3' Mode. By the way, the repair shops I called really didn't have a clue what the E3 code was. Dennis
