Question about LG DH404E Dehumidifier

1 Answer

I would appreciate if you could suggest some solution to this problem. I inadvertently pressed the temperature control minus button so the lowee reading went from 35 til ON. I would like to change it back up to 35 or possibly 40. When I press on the Minus buttoni it does not respond, and now the humidifier will run at least for the next two hours. I just did some maintenance on it, like cleaning the filter and the coils. In advance. Thanks

Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 30 minutes and plug it back in. Turn the Master ON/Off Switch to ON. The controls should have reverted back to the original factory settings. You can now, set the controls as you like.

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

    Thank you so much for getting back to me. I followed your instructions but am sorry to report it did not help. The setting still came back as ON. However, there is something else malfunctioning. Cold air escapes the groove where the front cover meets the top of the dehumidifier, condenses on top and turns to ice. I noticed that about a week ago. When removing the ice (I have not had the unit working for that period), I am afraid I might have damaged the "control panel'. I had it running for a while earlier in the day, the same thing happened, condensate on top and I switched the unit off. Perhaps I better place a service call to LG,or get a new unit.. Again, many thanks for your help.

    Sorry that didn't help. But, I now can say, that the Defrost Cycle is not functioning as it should. That probably was the problem from the start. I just didn't know that , at the time. I think you're wise to contact LG Tech Service. Thanks for the 4-Thumbs Up Rating. I really appreciate it.

How to set the controls


Since your Danby, discontinued model has several features that require a picture to understand how to set the controls, as well as how to use the remote control. I have provided a link to your Owner's Manual (in case you have misplaced yours) that you can download and print, for future reference.

http://www.danby.ca/cms/uploads/products/en_manual/DDR586R%20EFOM.pdf

The one thing I would suggest, that you keep in mind is that the lower the percentage of humidity extraction you set it on, the more humidity it will absorb. Which is what you want in the summer. Do Not press and hold the arrow down button. Press it down in increments, until you reach the level you desire.

Hope this helps you.

Hauier dehumidifier HDN305 suddenly won't turn on. No motor goes on and no red or green lights go on either. It's properly plugged in to a functioning electrical outlet which has a functioning...


You have already checked everything I would have suggested, so the only other thing I can think of is the temperature in the room, may be affecting it. If the ambient room temperature is above 112 degrees or below 32 degrees, the unit will shut OFF and not restart, until the temperature is within that range.
If you continue to have problems starting the unit, contact Haier America Customer Support 877-377-3639.

Hope this provided some help to you.

SETTING THE MACHINE TO TURN ON
1. Make sure the dehumidifier is plugged in but turned off.
2. Press the button with the clock symbol below it.
3. Press the up arrow to set how many hours until you want the machine to turn ON. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours.
4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity.
5. After the above steps are completed the dehumidifier will turn ON in the number of hours that you have set (programmed).

COMES ON BUT WON'T STAY ON


On dehumidifiers there are typically two sensors/switches that shut them off:

  1. One for when the drawer is removed; and
  2. One for when the drawer is full.
I would inspect those sensors/switches to see if they are being inadvertantly activated.

Kenmore Dehumidifier Won't Power On - No Lights, No Action


It sounds as if this may have electronic controls on it. If so, the problem could be related to too low of an ambient temperature or too low humidity in the air. If this design has a temperature sensor built into it, you may be experiencing "hibernation mode", where the unit will appear to be dead, when it is actually awaiting the proper temperature to employ itself.
The following statement is a parameter for all dehumidifiers and some of the control issues may vary, but the theory is the same.

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.

Humidity Control


Sounds like the button may be broken. However, it could be a loose wire. Take the front off and see if any of the wires connecting the control panel and the unit are loose or disconnected.

If there is a ribbon cable connecting the control panel, see if any of the contacts are exposed when you disconnect it. If they are, you may be able to use a pencil eraser to clean them off. A service man from Sears did this on the control panel for my ceramic-top stove. He said if that didn't work then I would have to buy new control panels, which were almost the cost of a new stove!

Will not power on after the electricity came back on in the house!


That capacitor is a run cap for the compressor. Your problem sounds like a faulty connection in the circuit which supplies power to the solid state electronics. The electronics will have a 115 VAC supply from the rest of the machine's circuitry, most likely running to a small transformer. Check for 115VAC when you attempt to start the machine. Trace the circuit until you find the point where the power disappears when the start is pushed. If this does not reveal the problem, replace the board that has the transformer on it. There is a faulty connection somewhere which is opening when power is drawn. It is also possible that the compressor is locked & drawing enough power to disable the rest of the machine. Try it with the compressor disconnected, before replacing anything.
