Question about LG Dehumidifiers

3 Answers

Our dehumidier runs, all the buttons respond, but no water is produced. We had a hose atached for a year , well last Summer, and i thought all was ok but i never saw water running. i figured it was because of the hose, it ran too slowly to see, but now i think it has not been producing water for a long time. i have detached the hose.

    i HAVE TRIED RUNNING IT WITH IT'S OWN WATER CONTAINER, BUT STILL NO WATER.

    HOW CAN ICHECK TO SEE IF THE COIL IS BAD/

    I took the rear cover off. I see one large black coil, which is clean and free of dust.

    I have an 18-Range Multitester. One of the measurements is for ohms.

    On the selector knob their are numbers that it can be set to for OHMS : RX1, RX 10, RX 1K.

    On top of the coil itself, there is a red wire attached to a loose fixture on one side and attached to a second fixtue are 3 , maybe 4 wire.

    What are the exact steps i need to do now to test/ what setting do i switch the tester to/

    Do i actually detach the wiring from the coil or just their covers. ? Do i plug in or unplug the Dehumidifier?

    I disconnected the connectors from the coil,plugged the Dehumidifier back in and turned it on. I attached the black and red probes from the multitester to the disconnected wires, but got no readings.??

  • johnnyde26 Sep 03, 2010

    I am afraid i must go out now, but will return in about 4 hrs. Please advise how i should proceed then

    thanks

    is the coil the black cyclinder about 6" high?

    Is it supposed to be cold when it is working properly?

    What about the short copper tubing, what is their role?

    So is it that I disconnect the wiring from top of black cyclinder and whith the unit plugged in and power turned on , i put the multitester prong to the connections on top of it? does it make any difference whether it is the red or black prong i am touching to a particular connection?

Here is part of a customer review on Amazon.com:
Cons: To get proper operation must set unit to 2 hour timer cycle. Unknowledgeable customer support.
Here is another review that describes the problem, and lack of support LG is providing:
tomeske's Full Review: LG DH504EL Dehumidifier Same story as another review I read. LG DH504EL Dehumidifier (Product number 3850A20500F) worked well, fairly quiet. Bought it June 10, 2005 from Home Depot. It is now May 18, 2006 and appears to be running. I can hear the compressor running, but it collects absolutely no water. Used only in my basement and was never moved or bumped. I cannot find it now on the LG website, they must know it is unreliable and discontinued producing or selling it. The LG Customer service put me on hold and then after 20 minutes, hung up. I'm sorry, but Life is Not So Good.

Lastly, but probably foremost, some of LG's humidifiers are on a recall list. Here's an excerpt from the web recall site:
Sold at: The Home Depot, Walmart and Heat Controller Inc. nationwide from January 2007 through June 2008 for between $140 and $150.
Manufactured in: China
Remedy: Consumers should immediately stop using the recalled dehumidifier, contact LG to determine if it is included in the recall and return it to an authorized LG service center for a free repair.
Consumer Contact: For additional information, contact LG toll-free at (877) 220-0479 between 8 a.m. and 7 p.m. CT Monday through Friday and between 8 a.m. and 2 p.m. CT on Saturday for the location of an authorized LG service center for the repair, or visit the firm’s Web site at www.30pintdehumidifierrecall.com

I think this is just a poor product, from the numerous reviews. Maybe your unit is on a recall list, hope so.
Good luck, hope this helps, and thanks for using FixYa.

You can try running the hose in a bucket or pan. The hose must be lower then the unit to properly drain. Make sure the filter is good as well so it can absorb the moisture.
The dehumidifier removes moisture from the air by passing the moist air over a cold dehumidifer coil. The moisture condenses out of the air on this coil and goes to the drain. You may have a bad coil

    you can use a voltmeter and test power to the coils. Make sure coils are clean and free of dust. You can also disconnect the wiring to the coils and use an ohmmeter and place one probe on each coil connection. You should get a reading, if not it's bad. If you do get a reading, then coil is good and refridgeration system is faulty and a tech with equipment would have to service it.

    Disconnect the coil. Set meter to RX1. Place a probe on each connector and check reading. Do this to all connectors.

    Not testing the wires, just the coil connections itself. The wires would have to be tested with a voltmeter, however it is peculiar you didn't get any ohm readings on the wires with the power on. May have a defective control board unit. Does all the lights and everything works except no water pickcup? If that's the case, board should be ok, coil is likely the problem. Test the coil with ohm setting RX1

    That would be the coil. It should be very warm when the machine is on. The tubes carry the liquid. The coil should be warm.

I have a danby dehumidifier...when I turn it on the fan goes on, but the actual dehumidier does not...the light about the first button does not light up. What Can i do?


It's probably in the wrong mode. This could be from a number of causes including you have not emptied the water chamber.

The dehumidifier is running constantly but no water is being collected


Sounds like you're in a wintery environment. Most people operate a humidifier in those locations because the air is too dry. If that is your situation, I suggest you turn the dehumidifier off until Summer and save electricity. If will pull moisture out of the air in the summer.

My dehumidier is not pulling any water into the bucket. Runs fine. About 1 year old.


If the unit is not pulling water into the bucket its probably not that humid in that area anymore. If it aint broke dont fix it.

The dehumidifier runs all day but there is only a little water being produced. We have humidity set at 35%, and the actual readings are much higher. This is only a year or so old. The last machine worked...


coolant may be low - warranty should be 5 years

If the room temperature 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 defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

Goldstar dehumidifier model DH305Y6 is there an outlet on this model for a hose so can drain into sump pump?


I have a Goldstar dehumidifier, Model DH305Y6. I bought it about 5 years ago at a local Walmart. During the summer I run it in the basement, here in south-central Pa. When it was brand new it worked very well, for about 2 yrs. Then it began turning on & off very irregularly. At first I thought it was the sensor on the front of the coils. So I moved it to the lower left side of the coils, and had the same results. The other day the water heater in the basement developed a leak. About 300 gals. of water covered the floor. After sumping/wet-vac'ing down to a wet carpet, I pulled out the dehumidifier and plugged it in,(the filter was cleaned before put away last summer). It began its on/off cycling again. It runs for about 2-3 mins., then shuts off for about 5-10 mins. So, I took the On/Off switch apart and read the resistance. It read 48k, for the 50k switch. I turned the switch all the way left to all the way right and it went from 48k, down to about 8k. The two wires to the switch were attached to the #2 and #3 poles,(only 3 poles). I did some testing, then removed the wires and re-soldered them to the #1 and #3 poles. I put everything back together, and now it works. It runs constantly, but it works/runs just fine. I need to get the basement dry, so I will let it run until the job is done. In the Spring I will get a new 50k potentiometer,(on/off switch), and see if that works. I will post results if I remember to.
