GE dehumidifer fan making loud knocking noise


possibly have to take motor and fan out as a unit to get fan off .

Dehumidifier started making a loud noise. Is this something we can fix?


a change in tone of the noise from a working unit indicates to me that a bit of dust/dirt has built up on the internal fans blades and has caused a imbalance in the fan now , this usually requires a complete disassembly and cleaning out to remedy

The fan in the dehumidifier makes an awful lot of noise.


It may not be the fan, as much as it the compressor vibrating. This occurs if the unit is not sitting on level flooring or on a carpet. Why I carpet? I do not know, but my LG unit does the same thing. I have found that smacking the sides of the cabinet simultaneously with my open hands, stops the vibration and the noise.

if however, it is the fan making the noise, it too can be affected by an UN-level surface. In addition, the fan shaft made need lubricating. WD40 works well for this or light machine oil (like sewing machine oil) will work too.

Hope this helps you & thanks for choosing FixYa.

Can you please help me find out what makes my fan motor slowly stops running after about 30 minutes. The unit runs fine but after about 30 minutes the motor sounds like it slowing down and wants to trip....


mcdevito75 here, It could be the capacitor if you can replace with same size do so. The Armature or communtator in the motor could be shorting also, do the capacitor the change the motor.

The dehumidifier's fan does not turn and makes a humming noise


first,make sure the fan blade hasn't gotten stuck on the shroud and cannot turn,then shut off machine and by-hand rotate fan and see if it spins to a stop after several rotations,if it stops quickly there is a bearing problem with the motor,this is normal after many years of service,then replace the motor

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 have a LG LHD45EL and the compressor works, fins chill but fan won't turn at all. I took it apart and cleaned the armature of the fan, Used a non-contact device to ensure electric is present in the...


let the unit cool down
with power on try sticking something in there to spin the fan blade
if it spins and continues to work it is a bad capacitor (little shiny metal can sometimes oval or round)
if it doesnt spin i would have to guess the motor is bad
hope this helps

Unit is noisy and rattling (70-pint) .....


There is nothing caught in the fan.  I have the same problem.  When taking the back off; unscrew and there our 2 tabs on the to edges about 2 inches in and on the bottom about 2 inches up on each side.  I can't seem to find an answer.   It appears that it could be the motor.  The fan spins freely when I spin it by hand.  I've tried to make adjustments from the fan side.  It looks like I would have to take the condenser coils off to get to the motor  potentially from the front.  Currently, I'm going to live with it because it is in the basement.  It looks like extended warranties are the way to go with dehumidifiers.  My Kenmoore has worked great at pulling water.  The problem has appeared after using a hose set up affecting the drainage.  When I buy another, even though this is my 2nd in 5 years.  But, I am buying the extend warranty this time.   These things break.
