Question about Goldstar DH304 Dehumidifier

1 Answer

Compressor runs but fan will not come on.

I have checked the switch and it works. I have also checked the power coming out of the control board going to the motor and there is continuity. How do I check to see if it is the motor that is bad?

Disconnect the motor leads for the fan motor, check the resistance through the motor when an Ohm meter. If you get no reading on the meter the motor is bad and needs to be replaced. also check the motor by rotating the fan. If it rotates with resistance the bearings may need lubrication. If it is a sealed bearing motor and no points for lubrication are there, replace the motor.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.

If you have a dehumidifier that is not producing any water then you are wondering what you need to do to get this thing to work for you. In some cases you may be able to do something and in other situations there may be nothing that you can do.

If you do not hear the compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.

A few things that can cause this are:

The circuit board relay has gone bad…replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.

The compressor has failed…if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.

If the compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.

If the compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.

If the compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.

If nothing is running, then you may also have a control board failure. Or the humidity sensor or humidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.

Also if nothing is running check the float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.

There are some parts available for a few brands, but with the prices for most of the parts that you can replace running anywhere from 40.00 – 80.00 dollars, replacement parts with labor to install them, makes a repair more then the few hundred dollar cost of many of these dehumidifiers.

As you can see there are quite a few things that can cause your dehumidifier not to work. Systematically go through the list and eliminate things to get to the bottom of the issue causing your problem and then decide if it is worth spending the money to try to fix the old unit. Only you can make that decision.

The compressor runs, but the fan doesnt work when we trouble shooted it. we found out it has power when we bypassed the switch and tested it. we pulled out the control box and it doesnt look like anything...


Hi, after reading you're problem, I found that you did the right thing.If you bypassed the switch and now you have power to the condenser motor but it doesn't operate, the motor is faulty, as you are eliminating the switch sending power to the fan motor. If you have power going into one side of the switch and you jumped it over, and the motor starts, the switch is at fault. So, you did the right thing! Sometimes you cant tell by looking at the switch wiring to no if it is at fault.In the field, we use jumper wires everyday to bypass components to check them out.In you're situation, both the compressor and condenser fan motor operate from this same switch, and the compressor was running. So, that tells me without having to bypass it that the fan motor is the faulty one, or the compressor would also be off. You may have to find one at a appliance parts house, or order one online. Sounds to me that you will have no problem changing this out. Best of luck to you, and Sincerely,

Dehumidifier won't run


After all that testing you have diagnosed the problem. It is the main circuit board. So there is not reason to do any more test. I would just get a new control board and off you go

The main switch is broken off and it does not turn on


You have to remove the entire wrapper to get to the control circuit board, make sure you unplug unit!! Locate the small white wires that plug into the board and go to the humidity switch.Unplug the connector at the board and plug the machine in and see if everything runs. ps make sure you reinstall the bucket or unit will not run. If machine runs replace that humidity control. The plug on the board is usually white. The other white wire is 4 the light. I hope this helps./

DH30 Dehumidifier Compressor Does not Operate


I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.

Normal operation, the unit has sensed icing and is in the defrost mode (compressor off and fan on high). When the ice melts normal operation will resume.
