SOURCE: Can't get our dehumidifer to

Bonnie, there are 5 basic, but solvable reason 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%.

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.

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

SOURCE: My Zenith dehumidifier model #zd300 will not work.

I had the very same problem with my Zenith ZD300 dehumidifier. After getting no help from the manufacturer and realizing that it was going to cost $45 just to figure out what was wrong with it, I dismantled the dehumidifier myself in search of a solution. I suspected it was the humidity sensor, so I ordered the part off Repair Clinic website (repairclinic.com). It cost $18.20 plus shipping. AND IT WORKED!! I was so relieved that I wouldn't have to buy a new dehumidifier. It's been running for a day now, so we will see. Here's the website link:

My dehumidifer is not drawing any water, but the fan continues to run.


There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture. humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

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

The Danby Millennium Dehumidifer goes not condense any more. Have unpluged the unit, cleaned all of the filters. Is there a way to reset the unit from the controls?


If you unplugged the heater for 12-15 minutes, after turning OFF the Master On/OFF Switch, the electronics should reset themselves. Also, be sure that you don't have the humidity level set to high. Anything above 60% wont' extract any moisture to speak of. If your unit doesn't have an LED display, set the unit on Minimum.

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

The dehumidifier runs, cycles on and off, but there is almost no water in the receptacle. I haven't had to empty it since it started cycling on & off this season. I usually have to empty it at...


You may have the humidity setting to high. Try lowering it to 45%. Or if yours doesn't have an LED Screen, set it for minimum. Also, check and clean the air intake filter, if you haven't already. Keep in mind, most dehumidifiers have a fan that may seem to run constantly, but the compressor doesn't turn ON. The fan is circulating air, in a effort to detect humidity levels that are higher than what you have the humidity removal set on.

Hope this helped you.

Dehumidifers runs but doesn't pull the water out air. I purchased this at Wal mart on 2/23/07.


There a couple of things you can do to hopefully solve this problem. Most of the time, the air intake filter is clogged and needs to be cleaned. In addition, the humidity level you have it set to, must be in direct correlation to the humidity in your home. Keep that in mind when setting the extraction setting.

Before you attempt to remove the filter, be sure you turn the Master ON/OFF Switch to OFF and then unplug the unit from the wall outlet.

If by the slim chance cleaning the filter doesn't solve the problem, the unit's compressor may need to be recharged with cooling refrigerant. This is something that is best left to a pro or a service center in your area.

Hope this helps you to continue to troubleshoot and solve the problem.

Dehumidifier runs but does not remove moisture.


If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defost over night.
Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

Dehumidifier Error?


Same problem with Goldstar model DH404EY7 -- stop code 01 on startup, bucket full light blinks (drains to floor).

Replaced the main controller board to fix it.

For my model dehumidifer the part # is 6871A20888A, and cost $77.44 (not counting shipping) from Appliance Factory Parts. The Appliance Factory Parts web site also provides parts breakdown (exploded parts diagram) diagrams and service manuals in PDF form.
