20 Most Recent Goldstar DH3010B Dehumidifier - Page 5 Questions & Answers

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.

what ever you doo just stand it back up for 24 hrs after work is done

Hi,
the bearing have siezed up on the fan... some WD-40 and then some oil may get it going agian...

Hi,
There are many reasons why a dehumidifier will not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier

Dehumidifier is running but no water is in bucket

The first thing I would check is to see if turning the humdity switch to lower the humidity turns the unit on. Then if that does not work, I would check to see if the bucket is making contact with the switch. It the switch that shuts the dehumidifier off when the bucket get full of water. Sometimes you can hear it click when the bucket hits the full state.

Not sure how technical you are, but if you are familiar with how to use a meter, I would check the bucket switch. I would check to see if the switch changes open/close depending on whether the switch is pressed.

If the switch is good, listen for any kind of hum from the unit. That could mean that the compressor, is unable to start. That could either mean you need a new compressor of a capacitor.

Hope this helps you.

Since you didn't post the manufacturer and model, this will be generalized.

Check the filters on the unit. Pay attention to presence of dirt on the coils of both the intake and the exhaust. They need to be clean and shiny.

Check your water level sensor. It may be choked with scale, and not able to move freely.

If you are using an extension cord, try plugging the unit directly to a wall outlet, or use a heavier guage cord (compressor overloading due to reduced voltage).

Post back the make and model if you can.

Hi,

Thanks for contacting Fixya.com

There are a couple of things that you can do. First try to use the needles on a meter to " meter out " continuity on the plug end. Just to see if the circuit isn't broke. Next open the case there should be at least a loose contact somewhere. it may not be visible but its best if you use continuity testers. Make sure the water bucket is in right and the little door is closed right. most of them won,t work otherwise.

Let us know if you have something more to know else please accept the suggestion.
Thank You.

Hi,

By trying to start do you mean the unit hums then clicks followed by a pause for a few minutes then repeats the process until it finally starts?

If so, this is an indication of a sealed system problem.

-It could be a restriction in one of the refrigerant lines causing a very slow equalization of pressures in-between cycles. If the unit is pulling good moisture from the air when it does run then this would not be the problem

-The compressor is weak and hard to start, this is more likely the cause, if it is not under warranty the cost of repairs would out typically out weight the value, as it is about a $300.00 repair to replace a compressor on a dehumidifier.

Let me know if you have questions.

put in the a new battery it should work fine

Don't pull too much or the will dry, squeak, crack - not less than 50% humidity

Check the voltage to the fan motor. More then likely the fan motor It is either frozen or burnt out.
Good Luck,

remove water bucket from cabinet. filter is above,pull down fitter will come out wash with soft brush and warm soapy water slide filter back in groove above. waa laa.....!

A few things you could try are to make sure the float isn't covered in gunk and moving sticky-like, make sure air filters are clean and the compressor isn't overheating, and make sure the humidistat (probably a knob that says drier with arrows) isn't turning the machine off because it's reached the set level.

normally the problem is either your evaporator is dirty or may be your systems isover charged,

you need a competent person to cean your systems and check gas pressures on the discharge and suction sde of your compressor.

Hi,

The humidity switch (Hydrometer sensor) may be at fault or compressor or fan is not running.
First You could go directly to the compressor and make sure it is or is not getting power first. If the compressor has power then the compressor is suspect (sometimes when 1 wont start it gets hot to the touch) In any case the fan(s) should run with it on and trying to dehumidify.

2 KINDS of CONTROLS for your DEHUMIDIFY
If it has an electronic display the sensor will be a small probe close to the inlet of the air inlet circulation. Maybe its not in place.This type control is not something that can usually be checked without an ohm meter, thermometer, and Hydrometer or Psychometric measuring device to arrive at the wet-dry bulb temperatures thus determining the humidity and charts to determine the resistance value of the sensor(s). So replace the board and sensor on this type

If everything is clean on the coils and the filter is clean it should work.
I would recomending you to contact LG because they have a 5 year warranty on LG GOLDSTAR dehumidifiers. Make sure that you have your reciept. Usually what they will do is locate a shop near you and it can be serviced there. LG will pay the bill. Or if there is no local shop they will send you a service tag for your old unit and ship you a replacement unit. Contact LG and explain this problem to you. Everything should be covered under warranty still

Please leave me comment, if you need further assistance

Replace the fan motor. Common problem on this model. Should be a cheap fix. Try ebay...

I assume the dehumidifier was working fine at some point at this is a new development.

First cause could be insufficient air flow through the unit. Make sure it is not backed up too close to a wall or drapes, etc. It needs sufficient airspace around it to be able to flow the correct amount of air through itself.
Also related to airflow, your model has a filter on the top rear of the unit; check it for clogging. It ll cause the same condition, insufficient airflow, if it is clogged.

Second, make sure you are not using it in too cold of an environment; You should not be using the dehumidifier in a room that is reaching temperatures of 70F +/- a degree or so. If you keep your temperature in the low 70s and must use the dehumidifier, try putting it on a dresser/etc to get it away from the cooler temperatures on the ground.

Last possible cause is a slightly undercharged unit will frost up as well. If the system is older and has developed a leak, as the refrigerant level decreases it will begin frosting up the coils and eventually fails to work normally. At this point your unit would require professional service as they contain toxic gases and require special equipment to discharge/charge/leaktest.
