SOURCE: dehumidifier

IS THE ROOM HUMIDITY LOW. IF IT IS BELOW 30% THE HUMIDISTAT WILL SHUT DOWN THE UNIT. THE AMMBIENT TEMP SHOULD BE ABOVE 65 DEGREES AND THE HUMIDITY SHOULD BE ABOVE 50 %.

SOURCE: runs 5 min then quits

Had the same problem and I too cut the white wires leading to the himidity level switch. The unit came on immediately and has worked ever since (with same limitations as mentioned in the first solution post).

Lg dehumidifier lhd30 normally removes an almost full bucket of water from my basement every 24 hours. Now in July it stopped doing so. I get about an inch of water per day now. If i turn the control down...


There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1& 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a mechanical unit,
uni, set the control knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor may have failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helped you to troubleshoot & solve the problem.

Model GHD30 dehumidifier-runs for a few minutes then shuts off. Will start again after a few minutes then shut off again, and so on. Does not seem to be "dehumifying" when operating.


As I have told many questioners, There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If your unit does not have an
LED screen, turn the control to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

My whirlpool dehumidifier fan runs, but no water is being taken out of the air; cleaned the filter and still no change; dehumidifier was purchased in August 2008.


Hello,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.

LG LHD30 the compressor does not cycle on


Compressor won’t Start
The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

Runs great but no water in bucket ,whats wrong


either there's no moisture in the house (especially if you have an air conditioner), the coils are not cold enough, or there's no air flow across the coils. if the latter is the case, clean off the rear coils, clean off the front filter (or if no filter, the fins), and see if the fan is working. cleaning the condenser coil fins in the front would also help with it not getting cold, if that were the problem.

Power lose


I have a 45 pint. I have to slide the bucket in and out of the unit multiple times. Make sure to wait a few seconds after each time to see if it will recognize no water (sometimes the red light comes on, but then changes it mind). Also, I've found that leaving the bucket a little crooked will make it respond. It sucks, I know. Mine is only a year old too. Should not be a problem like this!

Runs for a couple of minutes and then stops


Try cleaning out the air filter using cold water. I did not even know the unit had one until I had the same problem. Pull out the bucket. The filter is located where the front top edge of the bucket would be located if it were in the instrument. Remove it by pulling straight down. It may be taped to the instrument for shipping purposes. According to the manual, this should be done every month. I have had the machine since Katrina and this is the first time I have had a problem. Hope this helps.
