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".

How do I determine reason that my Danby Dehumidifier isn't cycling on to compressor for more than 3-4 seconds at a time? Fan always runs but compressor only kicks in for 3-4 seconds then back off.


I would say low on gas or bad switch/thermostat.
The compressor probably has a shutoff for low freon. You would need a set of gauges to check for that.
Bad thermostat? You'd need a ohm meter.
User error? What kinda settings or controls do you have on the control panel?
There was a recall on these in 2014 for catching on fire.

Just purchased a Danby dehumidifier (model # DDR6O11R). I was wondering when the dehumidifier reaches the programmed level of humidity (example: 40%). Is the unit suppose to shut off completely? I believe...


Depending on which mode you have the unit set on, will determine if it shots OFF entirely or the fan continues to run. In the Constant or Continual mode, the compressor will turn OFF, once the humidity extraction level has been reached. But, the fan will continue to operate, in an effort to keep the air circulating, so that if the humidity level rises, the compressor will turn ON and start extracting again.

In Timed Mode (usually 2 hour or 4 hour) , when the compressor turns OFF the fan does too.

Hope this helped you. Please let me know. Thanks.

I have a Danby Silhouette and the fan works but the dehumidifier doesnt.


Bryan, it may imply be a case of the humidity extraction level being set to high. Lower the level to 35% and see what happens. As far as the fan running is concerned. Most dehumidifiers are designed for the fan to run, even if the compressor doesn't turn ON. It's designed to keep the air circulating and if the humidity rises above the setting you have it on, the humidity sensor will pick up this change and turn the compressor ON.

Also, remove the air intake filter to see if it's clogged and needs cleaning. Maintain at least a minimum of 12" of free air space all around the dehumidifier. Poor air circulation will prevent the unit from working properly. As will, to low an ambient air tempeature. Most unit struggle to work at temperature between 40 & 60 degrees F.

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

It runs, the fan works in Hi and Lo, the compressor seems to work, it seems to blow warm air if the compressor is running and cold air when it is not. The mode switch does something but I am not sure...


Take it to a metal scrap yard and turn it in the copper and buy a new one. Buy a different brand.
Sorry to be so blunt but dehumidifiers are very cheap and disposable not many people work on them. If this help please rate me and do a testimonial.

Compressor stops at proper humidity % but the fan keeps running.


Dehumidifiers are built that way. They keep moving air so it is able to keep any change of conditions moving around the room. On a dehumidifier, it the fan stops, your unit will short cycle becasue water will naturally evaporate from the water tank and it would turn on, then off, then on then off. The way it runs now is fine. Running the fan 24 hours on your dehumidifier cost nickels a day. Just let run.

I just bought a Danby Dehumidifier model: DDR6009REE The fan runs constantly even when the humidity setting is reached and the compressor is off. has anyone patched the power for the fan by putting...


All new generation dehumidifiers are designed to have the fans run all the time and the compressor comes on when the relitive humidity rises above the setting that you have chosen. I spoke with the company and asked them why this is so, and they told me that it is more energy efficient to have the machine on all the time so that when the compressor kicks in there is a small draw on electricity.
Apparently when the old dehumidifiers came on it was the compressor that turned on immediately, and the fan, and this caused a very high current draw. The new design has the fan on all the time and this helps to circulate the air evenly around the area being dehumidified - thus more efficient overall coverage.
I understood their explanation, but still do not like this new method of operation.

Dehumidifier


Most dehumidifiers these days have a built in defrost control, which turns the compressor off when the coils frost up while the fan continues to blow to help melt the frost off, so if it is frosting you may need a new defrost control, but first check the following: If your model has an air filter, clean it, as restriction of air flow will contribute to icing. Try to move the unit to a warmer location. Usually the best way to do this is to get it above the floor as far as possible, as the air temp is warmer closer to the ceiling than it is at the floor. Make sure there is plenty of room for air to circulate. (don't push it against a wall)

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
