Open Question

Goldstar part no. 3850A20500F

The machine is year old or less. Does not condense water. Does not freeze coils. Machine starts up gets loud banging kind of sound gets louder then after while entire machine shuts down. I opened back up to watch. SAme procedure. Compressor is making the noise. Ratling around must not have any freon in it I assume. Will it be more to repair leak and fill or buy another brand. Or is goldstar maker liable.

SOURCE: Dehumidifier runs but does not condense water.

It sounds like an issue with the control bord. This dehumidifier should have a 5 year warranty through LG. You will need to have this serviced. If it is under warranty by LG they will either refer you to a local repair shop and they will pay for the repair or they will replace it if you do not have a repair shop in your area. Call them and explain the problem to them. Make sure that you have your reciept. Here is the contact information for LG:

clean filter and then check the coil behind the filter to see if clean. Biggest things that freeze a unit are dirty filter or coil...or low on freon.

The room is 70 degrees f but the coils still ice up. What is the problem?

Most of the time, the most common reason is a dirty or clogged air intake filter. Turn the Master ON/Off Switch to OFF and unplug the unit from the wall outlet. Put some old towels under the unit and allow it to thaw completely, before removing the filter for cleaning. Also, if you can access the cooling coils, wiping them down with warm water and a mild detergent (dish washing liquid is fine) rinse and dry completely. A light coating of WD40 after they're dry helps too.

Worse case scenario is that the compressor is low on refrigerant gas and needs recharging. Or the defrost sensor has failed and needs to be replaced.

Depending on the age of the unit, will determine if it's worth repairing. If it's over 5 years old, get a new one. Less than 5 years old, it's worth considering to have it repaired. Contact Goldstar Tech Service (800) 243-0000 for an idea on the cost of repair.

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

Product Goldstar Dehumidifier GHD30: Machine runs when red button is depressed by hand. Return water bucket and machine stops. Set theromstat controller on max, and when button is depressed it works and...


You need to check that the bucket is clean and that the sensor for the water level in the bucket is clean.

An old toothbrush and some warm soapy water can sometimes achieve a great result.

Failing this you may need a new sensor, be careful and either draw or photo the old wiring route with your cell phone to make it easier to fit the new sensor

Hope this helps

Is Part # 3850A20500F one of this model? my unit

I found the model # on my Goldstar DH304 at the top of a sticker on the inside of the unit behind the bucket. Mine has stopped working too. I'm awaiting an answer to my problem but after some research it seems that unless the filter and/or coils simply need cleaned, there is lttle that can be economically repaired. Good luck.

It is defective. The coils are not getting cold enough to condense water in the air. If you have the receipt and the unit is less than 5 years old, give LG a call for warranty repair.

GHD30 dehumidifier completely dead

If any machine is completely electrically dead it is a sign that there is no electrical voltage getting through to operate it. Using an electric meter it is a relatively easy task to find the point of differential voltages which would indicate where the open circuit is located. The blue green fluid found is from copper oxide and is not necessarily indicative of a refrigerant leak. Oil present would be an indicator of a refrigerant leak.

Dehumidifier runs loud

What is the temperature in the space where you are operating thsi dehumidifier? When you first start a refrigerating system some refrigerant may have condensed into the compressor oil. When the compressor starts the pressure in it drops rapidly. The oil boils and some passes through the compressor valves. After a few minutes of operation this condition normally corrects itself.
