Question about Goldstar DH504EL Dehumidifier

Open Question

I have a Goldstar Dehumidifier DH504ELY6 power turns on but it does not start. I have moisture in the room but still does not start the cycle can it be the sensor??

As I stated the dehumidifier would start to work when I hit power button or when I emptied the water resavoir and put it back. It does not do that anymore. The power is on. I have cleaned the sensor and the coils.How would I check to see if the sensor is working anymore?

I took my dehumidifier apart and I found why the unit no longer would start.

First, there is a fuse inside the metal compartment that houses the control circuit board.
However, the fuse was not blown. Instead I found the relay that controls the compressor,
(circuit diagram calls it RY-COMP) was not functioning and was left in the open position.
The relay must switch the compressor on/off based on humidity, full water hopper, and
maybe other factors like temperature.

The RY-COMP is a large black plastic component on the circuit board with two
wires (blue and black) connected at the top. I tested the contacts and they remained
open when starting up the dehumidifier. Doing a small bit of rewiring so that the blue and black wire
were connected and also wired to RY-COMP terminal 3, the dehumidifier came back to life.
However, this is good for proving what broke but without an electronic control to cycle the
unit on and off and to halt when the water hopper is full it's not a valuable alternative and
it risks a burnout of the compressor from constant use.

I think the RY-COMP relay is a solid state relay which could have gone bad from a spike
in voltage when plugging the unit in or cycling on/off.

I certainly don't want to buy another unit where the circuitry is not robust enough to survive
plugging in every couple weeks. I was thinking I could try replacing the relay with a magnet relay which would probably survive spikes much better.

The hose connector does not drain the bucket, it drains the condensate before it enters the bucket. Tube passes through back of dehumidifier by the cord wrap area. (you may have to remove a small cover)

Take cover off. First check the fuse on the circuit board. If it's blown replace it. That should get the motor running, the motor might be or is going out. If the motor is bad you'll have to replace the motor. If the fuse is good and the motor is good, unhook the wires on circuit board that go to the humidity control switch. If the unit comes on with the humidity control switch unhooked, you'll have to replace the humidity control switch. Sears has them for about $11.50. Hope this helps.

Stopped working

Does it act the same as if the bucket was removed? Likely your fill bucket switch is not connecting. Remove the bucket, press the switch and try to run the unit. If it powers up and "works" then you need to make sure the bucket has a good connection with the switch. If this did not work, remove the connectors to the switch and electrical tape them together and try running this again. If it works, your switch is bad. Replace. If you leave it electrical tape connected, the unit will not turn off when the bucket is full.

The dehumidifier runs and collects water. The issue is with the controls. None of them are working. In order to turn the unit off it must be unplugged.

My only guess is that there must be a relay inside the control panel that (like many relays) arced ar one time and partially welded itself in the on position. Good quality relays are plated with a high temperature melting point metal to prevent this. Being LG is Goldstar (a Korean company) they most likely use the cheapest relays. To solve this issue the relay needs a hard knock to it. (Don't hit it so hard as to break the circuit-board) :)

follow the instructions below on how to use your dehumidifier:

Prepare the room for the dehumidifier by vacuuming, dusting and cleaning the room. Be especially careful to have all mold removed prior to using the dehumidifier.
Plug in the dehumidifier into a grounded outlet.
Set the dehumidifier to high in order to remove excess moisture from the room.
Wait for the dehumidifier to run several cycles, removing all undesired moisture from the air. This may take days or even weeks in especially damp rooms.
Adjust the setting of the dehumidifier when the air has reached your desired comfort level. Make the setting one that will maintain the current conditions.
Good luck.

It seems as if the unit makes the room warmer. Is this normal?

Yes the heat is a byproduct of the compressor running....there will be a slight overall heat gain...this is very normal and nothing to be concerned about....the dehumidifier passes the air over a cold coil to pull out the moisture but also discharges the heat into the the net result is heat gain in the amount of electrical energy the dehumidifier is using...

The coils keep freezing on my gold star dehumidifier

Try turning the setting down lower in order to help the unit cycle on and off, rather than have to run constantly.

It could be that your situation requires more than one dehumidifier for the space you're trying to cover with this one unit. These units are not designed to operate 24/7 without cycling on and off frequently.

The situation you're experiencing tells me that you have either an extreme amount of moisture where the unit is placed, or the area is much to large for just one unit to handle. If you can issolate the unit to one area by closing a door, etc. if that isn't possible, you'll likely need another dehumidifier to help reduce the load on this one that's freezing up while helping reduce the amount of moisture in the area.

If that doesn't help, please provide more details about the area the unit is being used in and the size of the room, etc., so I can further assist you in solving the problem. Thanks!

Dehumidifier throws off hot air making the room very warm. Is that normal?

Yes! A dehumidifier is an entire AC system in one box. First the air passes thru a very cold coil causing moisture in the air to condense and run away. Then the air is re-heated thru a hot coil (the other half of the AC) and blown back into the room. The net result MUST be a net increase in temperature because of the heat added by the mechanical process.

Dehumidifier not collecting moisture

Normal 0 When you push the power button, the blower fan comes on. In a few minutes you should hear a second "click"--that is your compressor starting. Do you hear that second click?

Dehumidifier freezing up, is it the de-icer control? can it be replaced ?

Could be the tempurature of the room you have it in. Make sure it is not operating in a room below 65 degrees F or 18 C
