SOURCE: 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.

It is defective. The coils are not getting cold enough to condense water in the air. If you have the receipt and the unit is less than 5 years old, give LG a call for warranty repair.

My lg 65 pint dehumidifier is set at 40%. however it is turning on and off every 30 seconds or so. is this worth fixing considering it is 3 yrs old?


if thats where you run it at 40 i suspect it's overheating and shut off possibly broken now , one should never set a humidistat less than say 66%rh as a normal house is 70%rh and asking anything more of a home unit is just not possible if moisture is that much a problem try running two units about twenty feet apart , they will cycle more to cool down and will run longer , might even be more efficient than running one harder

I have a DDR7009EE and the fan runs continuously even when the humidity in the room is below the setting on the machine. Shouldn't the fan stop when the desired humidity is reached?


Lyle, your particular model is designed for the fan to function constantly. However, the fan running doesn't mean the compressor is always running. The reason the unit was designed this way, is for the air to be continually moving, and when the humidity sensor picks up a rise in the humidity level (above where you have it set) the compressor will turn ON and extract that humidity.

Your unit is working as it should. Thanks for choosing FixYa.

When the mode button is pushed, I only receive the option of dehumidifying, or just fan. The manual claims it has a heat option but it is not available. A friend of mine has the same one and they have the...


Sorry to read about your problem, I hope this helps you out.

Their has to be a model difference issue . I have checked the Manuel and have put a copy of the section, for modes. and their is no heat only mode.

Your unit uses heat anyway, so i really do not know how, heat only would help you. I would say to look at the sticker on your friends model, and see if the numbers are exact.

Default Setting:

When the unit is first connected to a power supply, the electronic circuit board will automatically default to the following factory settings;
Mode: Dehumidifier Humidity Set Air Value:60% RH Fan Speed: = Low

NOTE: In the event of a power failure or the unit is switched 'Off', the most recent settings are retained and restored once the power is switched "On"/resumed.
IMPORTANT NOTE: Depending on the ambient humidity conditions, when power is restored or switched 'On' the dehumidifier may not start automatically under the factory or custom (see page 7) default setting. This is an indica- tion that the ambient RH% level of the surrounding envi- ronment is lower than the current default setting and it may be necessary to select a lower set RH% value.
DRY MODE SELECTION: 1. The unit does not have to be switched on (opera- tional) to select/set a program. All programs can be selected with the unit in the "off" position.
2. Press the MODE button until the Dry symbol is shown in the mode area of the display. Note: Each time the MODE button is pressed, the setting will alternate between DRY (dehumidifier) and FAN (only) mode.

3. Press the or cursor buttons to select the desired RH% operating value. To select CONTINUOUS operation,pressthe buttonuntilthesymbol"--" appears in the SET AIR display. During CONTINUOUS mode operation, the humidistat (control) will be by-passed and the compressor will operate non-stop regardless of humidity conditions.
FAN SPEED SELECTION:

4. Press the fan symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options. The fan speed you select will appear in the LED display; either a 4 blade fan symbol for 'high fan' or a 3 blade fan symbol for 'low fan' will be shown in the display area.

5. When all settings are complete, press the I/O button to start the selected operation (MODE) and the blue opera- tion light will illuminate.

FAN ONLY MODE SELECTION:
1. Press the MODE button until the fan blade symbol is shown in the mode area of the display. 2. Press the "Fan" symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options.
3. When all settings are complete, press the on/off button to start fan mode operation and the blue operation light will illuminate.

I have Haier DE45EJ-L I am confused at what the setting should be. The Temperture is 68, when I put the humidity setting at 50 it shuts down, if I put it to 38 moisture is removed from the air. All the...


The unit shuts down when set at 50% because the controller is sensing that the humidity is below 50% RH. It comes on when set at 38 because the RH is higher, so it will try and dehumidify down to 38% RH.
According to the EPA the ideal RH in a conditioned space is 48 to 54%. You can set it and leave it at 50% if you are comfortable there and the dehumidifier will automatically come on when the RH is above 50% and will automatically turn off when the RH is 50% or below.

My new Danby dehumidifier never shuts off


This unit is designed with the intention of the fan running all the time. The compressor cycles on and off with demand, however the fan runs continuously to provide constant room circulation.

Humidifier Fan Doesn't Stop


RH at 70 % seems to me a little excessive you really should be working somewhere around 50 to 56% the fan has to move Air through the system.
I would like to know your room Air temp what is the Air temp comming off the system. what are your parameters.

LG LD65E humidity variance


Is the compressor running or is it just the fan? If its just the fan it is because it is cycling the air and it uses that air flow to check the humidity in the air. If the fan runs non-stop and the compressor does not turn on or the fan does not shut off there is a problem with this unit and you will need to replace it. Since it is brand new you should still be able to return it to the store.
