Question about Goldstar DH504EL Dehumidifier
Posted by Anonymous on
SOURCE: NO POWER TO MY DEHUMIDIFIER
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.

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.

Only available for DjVu reader (download link on LG site). You'll need to download and install the plugin then close and relaunch your browser. I was only able to get it to work in IE in the end with Firefox and Chrome not working. IE objected I had to "allow" the plugin to run then once again close and relaunch the browser then it finally worked. Good Luck!
