Question about Goldstar DH3010B Dehumidifier

1 Answer

Fan motor stopped working, replacement went out too!

My fan motor quit working so I replaced it, I installed the new motor and it seemed to run fine. About an hour later I checked on things and the whole dehumidifier was hot, the compressor felt very hot and the motor was also extremely hot. The motor was inoperable. After letting the machine cool for a day, I tried it again, the compressor kicked on but the fan motor failed to start. Any ideas?

    Fan motor ran for a short time but at a very low speed/level. Everything then just stopped and it got very hot to the point where I unplugged it.

I would look for another outlet for you to plug it in before you start anything elaborate. I assume you've done this already but spin the motor/blade. If it spins and there is little or no play in the shaft or blades causing a blade to bind up the mechanical part seems ok.

Now if you have a volt meter First check the motor for voltage, Then if you have voltage, compare it to the rating on the motor. Usually a voltage within 10% is ok. Next test resistance on the wires of the motor any resistance and the winding is probably okay. If not then the motor is out again. If you have lost voltage the control board is your next part to test. No voltage out to the motor there on the board plug and the board is the problem Power there woudl mean the motor has too high a resistance and Id check the resistance on a differant known good motor before replacing it. just so you know where you started.

Hi,


There are many reasons why a dehumidifier will not work or collect water.

I just replaced the thermal fuse as described by several of your people for a fan motor on a Kenmore dihumidifier 580.54701400. The unit ran fine for about an hour and then stopped with a burning smell...


Your call on the $39 replacement replacing the whole thing.
did the TCO you put int have the same specs (temperature) as the one you replaced? I've replaced a lot of these and they'll keep running.
The burning smell points to a failing coil which creates the heat which opens the TCO. you already know how to get the motor coil out so I think the $39 options is better.

I have a Kenmore 54701 Dehumidifer that quit working is there any thing to look for or just throw it out and buy a new one


Is it not powering at all? Remove cabinet and check glass fuse on power supply board

Is it running but no water?
Check to see if fan is blowing; if not then thermosenser on fan motor blown

Fan and compressor running but no water? Maybe the room is already dry; if not than probably have coolant leak - not worth fixing

Fan will not come on.


The fan has to run if the compressor is running as the fan assists in removing the heat from the condenser coil. Can you spin the fan by hand? If there is full power(120 volts) to the fan and it isn't running then the fan motor is bad. Also, if the fan motor has a run capacitor this could keep the fan from running(if the capacitor is defective) so look for this first.

MY unit has become increasing noisy and the fan is the mane cause. The fan is now making different noises at differing levels high and low of loudness, and it often quits running all togetger. It is also...


It sounds like the bearings in the motor are worn out, especially as you said it quits running at times. You should be safe in just replacing the fan motor, but check the fan blade to make sure it isn't out of balance for any reason(dirty, missing a balance weight, or bent). Hope I was of assistence!

After about 5 minutes the unit stops working. No sound or even a fan noise. I just cleaned the filter to see if that helps, but it didn't.


Is the fan running and stopping before the unit completely quits?
If the fan quits the compressor won't run very long.
I would start with the fan motor or capacitor.
Shut the power off to the unit, spin the blower wheel to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.

I wonder if a little squirt of WD40 would go a long way in preventing the rust problem?
